1) Living organisms arose from non-living matter by a purely natural mechanism…
- 7. Since the alternative is neither falsifiable nor scientifically proven.
…that is well understood.
- 4. There are plausible mechanisms, but the actual one is not known (yet).

2) All organisms alive today share common ancestry at some time in the remote past.
- 7. The molecular data supporting this are overwhelming. The viruses share also a common ancestry with all other organisms; they use our genetic code.

3) All organisms alive today reached their modern form as a result of mechanisms that are well understood by science (e.g., mutation, natural selection, drift, and the other elements in the modern theory of evolution).
- 7. That’s the current theory of evolution.

4) Supernatural intervention has played no role in the development of living organisms as we see them today.
- see 1)

5) Supernatural forces are not required to account for the development of living organisms as we see them today.
- see 1)

6) Human beings are related to other species.
- 7.

7) The physical form and behavior of human beings have been shaped by natural selection.
- Not completely true regarding our morphology: 4. You need to add the genetic drift. If you do: 7 (no other mechanisms of evolution are known).
- Regarding our behavior (and culture), its heritability (essentially through learning) does not meet the requirements for natural selection to act: 1.

8) Supernatural intervention played no role in the rise of human consciousness and culture, including moral and religious impulses.
- See 1). AFAIK, none of the godly interventions mentioned in the bible has been scientifically proven.

9) Supernatural forces are not required to account for human consciousness and culture, including moral and religious impulses.
- See 1).

10) Natural selection is responsible for the rise of human consciousness and culture, including moral and religious impulses.
- Regarding our consciousness: 6. The biological material for human consciousness is not precisely known, but it resides certainly in our body, which evolved through natural selection and/or genetic drift.
- Regarding our culture, see 7).

I hope this helps.

Even if there were a truly massive extinction event, are there any sufficiently unspecialized lifeforms that could give rise to another Cambrian Explosion?  What's left?

I don't think this is related to specialization, which mainly refers to the ecological niche. Humans are not so specialized after all. ;)

Ecological specialization is often seen as a dead-end, because of the competition between species (niche assembly). It's no longer the case if this competition (including predation, etc) disappears.
For example, the modern sponges could be seen nowadays as ecologically "specialized" species (which is subjective). If the other animals dy in a cataclysm, I'm pretty sure that the absence of predators/competitors would allow the modern sponges to explore new niches and produce new body plants, as their ancestors did before the cambrian.

I've been following this guy Davison for quite some time and I have to tell you he is no dummy. He has a mastery of the classical evolutionary literature. Quite frankly I believe he has put forth a darn convincing scenario that evolution is finished and probably will not ever resume. He is also convinced that sexual reproduction can't perform even speciation at least in the lab.He keeps putting out challenges and nobody responds to him. I am no expert but I have the feeling he is onto something pretty darn revolutionary. From what he said over at his blog I doubt if he would return to Panda's Thumb even if you invited him. He seems pretty hostile to me. I think it would darn interesting if he did. Hells bells - why not ask him?

"Evolution is finished"
What about speciation events and natural selection currently observed in the wild? What about artificial selection in the lab or in the farm?
What about you're children being slightly different from you? Even this is evolution.
If he thinks that evolution is just the rise of new body plans, by other mechanisms than mutations and selection (+ genetic drift), then he is missing something.
And what's this argument anyway? Evolution is finished, so now the Great Designer is in charge? Does Mr. Davison support ID?

"...and probably will not resume"
Did Mr. Davison calculate some probability?

"Sexual reproduction can't perform speciation"
Is this Davison's argument? I doubt it because this is just nonsense. Species can only be defined via sexual reproduction. There is no concept of speciation without sexual reproduction. And I like the "at least in the lab" part that clearly demonstrates that this process is not possible in the wild. Anyway this is wrong since species of Drosophila have been separated from single populations in lab conditions, and a few years. Also, many plant species are produced via hybridizing (even in the lab).

It is commonly held that speciation processes are largely, if not totally, independent of natural selection.

This not commonly held.
Speciation often seems independent of natural selection, yes ; but selection can also boost the process. You can search for "ecological speciation", (a concept pioneered by Dolph Schluter) or "sympatric speciation in cychlids fishes" for example.

 I'm talking about the specializations that give rise to phyla - having skeletons, having diversified tissues, having exoskeletons, bilateral symmetry, etc.  My understanding (which may be incorrect) is that once certain features are developed by organisms, they can no longer follow a different "pathway", since the changes necessary to remove major features are so large that they're essentially impossible.

I don't think that mammals could ever lose their skeletons and develop exoskeletons, regardless of the niches they might expand into.  The process of evolving into mammals from less differentiated organisms is irreversible.

Fine, but your conception is not referred to as "specialization" in the scientific community (I am a PhD student). It may be called complexity.
Anyway, you're right. Humans probably cannot give rise to a new body plan without some macromutations (in development genes for instance), and viable macromutations never were revealed in the wild, AFAIK.
But maybe humans can evolve in something quite different in morphology and "ecology" even if the body plan remains the same, the same way some dinosaurs evolved into birds.

However, it is plausible that a sponge (as I said before) could evolve in something like a cnidarian, through mutation, drift and selection, IF its environment (including its competitors) allows this.

I'm sure that is the generally accepted view, Caledonian. Which is why JAD's assertion that evolution only takes a species to eventual extinction may have a ring of truth. Once a species has found its niche, rapid environmental change will leave it "high and dry" and less developed species can take over the territory.

"Is ecological specialization a dead-end ?"
"The jack-of-all-trades is master of none"
Theses two sentences have been the subject of manny debates in the scientific world. You can find hundreds (if not thousands) of papers on that topic. ;)

Edit: it is not scientifically correct to say that a species "finds its niche" since the concept of niche is defined by the species itself. A species always fits in its ecological niche.
You could say "a species becomes specialized" or "a species fits in its new environment" or "a species changes its habitat and resources"...

Thank you for the terminology correction.  It's been a long time since I studied biology, and quite frankly I've forgotten most of the technical terms.

My impression is that even sponges are far more complex than whatever ur-creatures gave rise to all of the strange body plans we see from the Cambrian.  I suspect that life may have lost the flexibility needed to produce complexity from scratch.

Would modern bacteria ever develop into multicellular organisms if all other forms of life were destroyed?  Algal mats might be able to start over... maybe.

Well, I don't think that modern sponges are so different from cambrian sponges, but I'm not a paleontologist.

Was the ancestor of all the animals something we would assign to the porifera phylum? Or something else much simpler? I think no one knows.
But remember, animals are just very tiny branch in the tree of life.

You may be right, but we don't know anything about this.

The question Mivart asked was "How can natural selection possibly affect a structure that has not yet appeared?" The answer is it can't because natural selection never had anything to do with evolution any way and neither did sexual reproduction

No, the answer is it can't because natural selection doesn't produce new structures, mutations do.

In my mind, this turns out to be something of a semantic question. Obviously, Darwin wasn't opining about changes in nucleic acid sequences; he was looking at observable differences, and in that area I'm not so sure natural selection doesn't still reign supreme.


Dawkins's answer to the question echoes that sentiment. Nevertheless, the fact is that natural selection does not account for most evolutionary change.

... at the molecular level.
This is the neutral theory of Motoo Kimura, indeed.
It is my opinion, but substitutions of billions of non-coding nucleotides don't represent any "evolutionary change". They don't have any impact on the phenotype.

Who said that they are all non-coding? Neutral is not synonymous with "silent".

You're right. "Neutral" doesn't refer to mutations that have no effect on phenotype (silent), it refers to mutations that don't affect fitness.
However, as toejam has just pointed out, I don't think we can assert that most phenotypic changes do not affect the fitness of individuals.
And we would have to assign some relative weight to the “evolutionary changes” we measure. Should we consider a mutation in the junk DNA as important as a mutation in a hox gene, which could cause a major morphological change?

'Neutral evolution' seems a bit pedantic to me - a bit like saying that the main change in Wesley R.

Technically correct to say this the 'main' form of change - but in terms of importance in any other sense? - perhaps not.

That is a fair remark Dean, but we are talking about "evolutionary changes", changes that can be inherited.
Metabolism, maturation, growth, phenotypic plasticity... don't belong to this category.

Seems like a pretty empty invitation.

Actually, we can't asnwer their question. No one can prove that random mutations + selection is responsible for the rise of the eukaryotes.
For this, we would have to test most of the intermediate forms from prokaryotes to eukaryotes (which disappeared more than a billion years ago), detect wich mutations occured and measure their benefits on fitness (not in the lab since it does not perfectly match natural conditions).
Of course, we do have evidence that eukaryotes evolved from prokaryotes, and natural selection is certainly the factor acting here (since we don't know any other evolution mechanism, except drift), but we can't prove it nor test it, AFAIK.

There millions upon millions of uncataloged species alive today and they represent only 0.1% of all the species that ever lived.  We haven't even begun to glimpse the bounds of genomic diversity and probably won't ever be able to as 99.9% of all the genomes that ever existed are irretrievably destroyed beyond any ability to sequence or even weigh them.  The first life on earth could have been what someone (somone who unfortunately seems to be a moderation victim and so I cannot ask directly) called a phylogenetic stem cell.  This just another way of saying life on earth began as a seed, if you will, designed to unfold in a more less planned manner much as a human egg is designed to unfold into a human.

If you ignore the question of where the first cell (or cell comes from) which I might remind you is what neodarwinian evolutionary theory does regarding abiogenesis then one can presume it was any size at all of any arbitrary complexity.   Ontogeny and phylogeny have many striking parallels.  Why refuse to consider that one more parallel is that both ontogeny and phylogeny start from a cell programmed to diversify in a defined sequence of events with the environment serving only as a trigger to initiate the next programmed stage?

This theory (front loading?) is neither scientific nor productive. It is just a  new parade of IDers who can't deny common descent anymore.

First, it requires a programmer that could be supernatural, which is not falsifiable, or natural (extra-terrestrials, time travelers), which only pushes the problem further.

You are talking about the majority of species that have disappeared. This is correct, but did they disappear because they were programmed to or because they didn't fit their environment anymore? In this case, it would sound like natural selection, doesn't it?

If there is no natural selection, how are the living species so magically adapted to their environment? Did the Great Programmer, when He programmed LUCA with all the required genes for the future, anticipate all the interactions between organisms and their abiotic environment that would occur billions of years later, given that the biosphere was disturbed by several accidental events (asteroids, etc)? Or was He just very lucky? Maybe Bill can calculate His luck in terms of probability here, and compare it to the probability of adaptation by natural selection. ;)

Given that LUCA should have been a huge cell in order to contain the genes required for all the future living beings, why are the oldest fossils only small bacteria than can only contain a small chromosome? Where are LUCA’s huge descendents that are supposed to contain all these genes?

Also, when has such a pre-programmed evolution stopped, because we don't see it acting nowadays? However, we do have some strong evidence of evolution by mutations, genetic drift and/or natural selection. Just check the last week issue of Nature, you can see two striking examples of adaptive sympatric speciation.

And the analogy between ontology and phylogeny is only observable in animals, which represent a tiny branch in the tree of life.

She says ID is unscientific because-
"First, it requires a programmer that could be supernatural, which is not falsifiable,"

And so this is a kind of circle that is going on. If the scientist decides that evidence simply cannot point to the supernatural, even indirectly, then what are we to do if our universe was indeed caused by an intelligence or self-existing entity? Science would forever bar itself from discovering truth.

You don't quite understand what "falsifiable" means.

It doesn't mean we cannot prove the existence of a supernatural, it means that we cannot disprove (falsify) it.

Examples: if we find some clear hidden message in our Junk DNA (a paragraph from the Genesis or whatever), if we find this kind of message written on the rocks of Mars... these could be seen as evidence of God.
However, you will never provide a natural fact that could disprove the existence of a supernatural. Therefore your theory involving a supernatural (ID) is not falsifiable because absolutely anything could support it.

If design = supernatural, and supernatural= nonscientific then we have a problem if evidence points toward design.

As far as we know, nothing in biology points to design. The DI has yet to provide some results that prove irreducible complexity.

If we find evidence for design, the first thing to do is to search for the designer.

Design != supernatural, however design = intelligence.

There are also two cases of sympatric speciation reported in Nature, 10 days ago: one in cichlid fishes, one in palms.
Sympatric speciation involves disruptive selection, this is an adaptive mode of speciation.
Speciation without isolation (except hybridation) has always been controversial, but the last discoveries provide some indisputable evidence of its existence.

“Darwin’s famous book was called ‘On the Origin of Species,’ but it was really about natural selection on traits rather than species formation. Since our study suggests that natural selection is a general cause of species formation, it seems that Darwin chose an appropriate title after all.”


They have to be careful with such a claim. What is “a general cause of species formation”… > 50 % of species formation, > 5% …?
Their published results show an association between ecological divergence and reproductive isolation in all the tested taxa, at the same level of genetic distance (= time of evolution in generations). From this, we can suppose that ecological divergence (= adaptation) accelerate reproductive isolation, hence speciation. This is an important result but it doesn't demonstrate that natural selection is involved in most speciation events.
Example: in angiosperms, they show a high positive correlation between species' habitat and post-mating isolation (r=0.43). Ok, in this phylum, ecological divergence seems to accelerate speciation. However, we can still imagine the possibility that most species pairs (90 %) developed reproductive isolation very slowly through allopatry and genetic drift, and that only a small percentage of angiosperm species diverged rapidly through their adaptation to different habitats. This would produce a highly significant correlation as well.
Nevertheless, their huge dataset should easily provide an answer to my interrogation. Maybe a more complete paper is on its way. :)

I'd like to comment my own imprecision.
Actually, estimating the role of ecology in the speciation process is not so trivial. When two allopatric sibling species occupy two very close niches (i.e. small ecological divergence), what exactly is the impact of natural selection in their reproductive isolation (in the case of a secondary contact between both species)?

Taken together, we present astrong case where only sympatric speciation can account for the origin of a new species from a more widespread one in Lake Apoyoin, 10,000yr (Supplementary Table2). The Lake Apoyo population of the Midas cichlid and the  Arrow cichlid form a monophyletic assemblage (Fig. 2andSupplementaryFig. 3); they are reproductively completely isolated as shown by mate-choice experiments and the analyses of three sets of molecular markers (Table1) ; they are sympatrically distributed, no genetic structuring was detectedin A. citrinellus and A. zaliosus, and even individuals from opposite sides of the crater lake show no sign of differentiation (SupplementaryTable4, SupplementaryFig. 4). The recent volcanic origin of Lake Apoyo, its small size, its degree of isolation, the homogeneous habitat and the sympatric occurrence of both species throughout the lake, as well as the absence of genetic structure in each of the two species rule out the possibility of micro-allopatric or parapatric differentiation.

Well, dog races belong to the same species, and diverged from wolves only 12000 years ago IIRC, they can still interbreed. Human and chimp lineages diverged millions of years ago.

However, I don't understand JAD's comment:
Quote
You may also tell him why they are all the same species. It is because their karyotypes are basically identical and all the differences that they exhibit are due to Mendelian alleles, none of which ever had anything to do with organic evolution. You see as long as chromosomes can pair properly at meiosis I they will separate to form balanced functional haploid gametes at the end of meiosis.

Does he mean that dog races never evolve the phenotypic differences they show today?
And he is referring to a particular barrier in sexual reproduction: gametic compatibility. I think he overestimates the importance of meiosis in speciation. Sure, gametic incompatibility is a particular form of pre-zygotic isolation, but there are many forms of reproductive isolation, including pre-mating and post-zygotic barriers.

Ok, it's my turn to post the answer I posted on PT:

The maximum level of divergence between two gene sequences is 75 %, which is the average divergence between two random sequences.
Of course natural selection can impose constraints to mutations and the maximum level of divergence between two sequences may be lower, but I’m not certain of that.
Gene sequence comparisons between distant taxa are almost exclusively used in phylogenetic studies, AFAIK. A gene that has reached its maximum level of divergence between different given taxa is useless for the phylogenetic inference regarding these taxa. That explains why you never saw a phylogeny that puts mammals, bacteria, and yeats at the same distance, in what we call a “rake” (not sure whether the translation from French “rateau” applies here).
Lots of genes do not qualify for large scale phylogenetic studies, some of them do not even exist in all taxa and others have reached their maximum level of divergence (75% or less).

My message is clear enough to most experts in the field. ... First, I mean protein sequence homology not DNA.

Well, your message wasn't clear enough even for experts because you were talking about genes, not proteins.


Anyway, I don't see the difference. I suppose that lots of proteins are not suitable for large scale phylogenies based on amino acid sequences, because they evolve too fast and have reached their maximum divergence between distant lineages. Cyt b and COI maybe...?

But you raised an interesting point, it could be very instructive to compare the maximum level of divergence (if there is any) for several proteins found in almost all living beings.

However, "Darwinism" does not predict a minimum level of identity between too homologous proteins since a protein doesn't have keep the same function forever.

Shi,

Cyt C transfers electrons from complex n° 3 to complex n° 4 in the microchondrium internal membrane, IIRC. That's its function.
So cyt c co-evolves with these two protein complexes (at least) and these complexes also co-evlove with other proteins.

I don't see the reason why there should be a minimal level of identity for homologous cytochromes C just because ATP is produced at the end of the reaction chain.

EDIT: thank you Mr Cox, that was a better answer than I could ever give in English (or even in French after all ;)).

EDIT 2: Shi, phylogenetic inferences are not based on sequence identities anymore (phenetics). We identify precisely all the mutations that occured in each lineage, regardless of the distance between sequences (cladistics).

Author: jeannot
Shi, the neutral theory of molecular evolution only applies for neutral mutations. If you think that all amino acid substitutions in Cyt C are neutral, you are plain wrong. Therefore I suggest that you read some books or papers on protein evolution before arguing with Mr Cox who knows far more than you do on this topic.

The theory of evolution does not rely on the molecular clock (which does not very well apply to amino acid sequences). I fail to understand why you think it should. The mutation rate of cyt C is just an average between lineages.
And you seem to confuse genetic distance with mutations.

[BTW, the neutral theory is NOT Darwinism (= evolution by natural selection).]

After a very long time of evolution, lineages that share a common ancestor will become too much different for scientists to infer their common descent therefore... huh... there is no common descent?  ???

Darwinian explanation 1: time is not enough and there is no limit on minimal identity.
...
The phenomenon of conserved domains also invalidates such assumption.  So, the reason that the pattern in paragraph 3 has not been observed is not because time is not long enough or because of no limit on minimal identity.  
Well, we don't know if the bacterian lineages we have today diverged 3 billions years ago. Most of them are probably extinct. But if you compare bacteria with archea, their level divergence appears pretty huge. Wich proves that only two very ancient prokaryote lineages have survived.
Quote

Darwinian explanation 2: proteins in advanced species gain extra functions
(The concept of "advanced species" is not supported by any objective fact.) This hypothesis should apply to a very limited set of proteins. We told you that proteins can evolve through co-evolution with other proteins. I don't see any extra functions here.
Quote

Even if time is enough and there are limits to diversity, Darwinism can try the following explanation.  The reason that human shows 35% identity in cyto C with bacteria but not any lower is because 35% is the minimal identity allowed and will stay unchanged forever once reached.  The reason that human shows 60% identity in cyto C with yeast but not any lower is the same.  
Why do you think it should be the same reason?
Quote

If this is true, Darwinism must assume that a protein in yeast has gained some extra functions compared with its homolog in bacteria.  So more portions of the protein are resistant to change.  This may be true for some proteins.  But it is hard to believe that all proteins in yeast have gained extra functions compared with their homologs in bacteria.  This explanation requires us to believe in an ad hoc hypothesis that is unlikely to be true.
I don't quite follow you. You say that yeasts proteins should have gained extra functions because they show higher identities with ours?
Anyway, your two hypothesis are not mutually exclusive. If you compare DNA sequences (I don't know why you stick to amino acids sequences since DNA is the material of heredity, not proteins), you will notice that non-coding sequences reach the maximal level of divergence (75%) very fast in their evolution so that we can detect homologies anymore. That is your first hypothesis. Genes show different levels of divergence, depending on their function. Fundamental genes such as 16 S rDNA can be used to build the tree of life. Cyt b cannot because its level of divergence between lineages increases too fast. So maybe there is a minimum level of identity for 16s rDNAs, but we don't know it for sure and we don't know when lineages will reach it.
Quote

The alternative:
One possible alternative interpretation of all the facts is that maximum species divergence is set up at the beginning and stay unchanged during evolution.  The 35% identity between bacteria and eukaryotes in cyto C was established already 1000 myr ago and stayed largely unchanged during evolution and will remain unchanged in the future.  The 60% identity between yeast and multicelluar eukaryotes in cyto C was established in the beginning.  The more recent the species split, the less diverged versions are used.  We may yet to have a mechanism for how this may occur.
Indeed, you have to. Since you refer to Cyt C, should this mechanism take the theory of endosymbiosis into account?
Quote

But there exist many facts at the level of phenotypes that show that maximum phenotype distance is established at the beginning of species split and remains unchanged during evolution. The lack of intermediate transition species in the fossil record and the persistence of the same fossil structure over millions of years are examples of maximum distance at the beginning that stays unchanged through evolution.  
You should also learn more on fossilization. I recommend you to check talkorigins.org
Quote

The 5 finger pattern of land vertebrates has stayed unchanged for 400 myr since its arrival on earth.
And I didn't know that birds and cetartiodactyles had 5 fingers. Anyway what's your point? Does this disprove Neodarwinism?

The distance between land vertebrates and fish in the 5 finger design has remained at the same level since the design appeared...
Sorry I don't get your point.
Quote
...and is likely to remain unchanged forever in the future.
Why?
Quote

It is only logical to conclude that the genetic distance responsible for such phenotype distance has also remained the same since the appearance of the 5 finger design and its related genes.
The probleme is: what mutations in what genes are required to modify the number of fingers? We don't expect a single gene controling the number of fingers with one allele for each number.  
Quote

A self-destructive flaw:
The simple thought experiment on protein homology reveals a self-destructive flaw with the present theory. Both change and no-change or stability are fundamental facts of past life history on earth.  If change/mutation explains both sides of the coin, i.e., change and no-change in phenotype, it explains neither.  A living fossil has remained phenotypically unchanged for millions of years. But Darwinism plus its ad hoc hypothesis the neutral theory...
The neutral theory have been confirmed by many experiments and studies (which also involve micro-evolution that IDers can't deny anymore). You should read more about it.
Quote

... requires us to believe (without any facts) that its genotype has changed dramatically. The theory has no way to explain how phenotype stability is maintained by changes in genes.  If change in phenotype is explained by changes in genes, the same theory is self-destructive to say that no-change in phenotype is also explained by changes in genes.

If you've found a link between 16 S rDNA or Cyt C and morphology, you should publish, indeed.

Depending on the genetic sequence you use, you can easily show the same distance between humans, yeasts and bacteria.

Shi, we all fail to get your point.

"Darwinism" makes NO prediction about any minimal level of identity between nucleotids or amino acid sequences in genes or proteins (above the typical 1/4 and 1/20 respectively).
As we told you, a protein may change its function, gain new ones or co-evolve with other proteins while remaining functional. Anything is possible as long as it doesn't alter its organism's fitness.
If you think that some proteins should have some minimal level of identity across distant lineages (maybe this is true in some cases, I'm not a expert in protein evolution) it's your concern, not ours, because it as nothing to see with the falsification of common descent.
You can go to NCBI or genebank, get some proteins sequences and perform all the distance comparisons you like. Maybe you'll find some interesting things that confirm or contradict your thoughts.
Good luck.

Okay. But you still need to explain why human, plant, insects, and fish all show equal identity (equal distance) to yeast in cytoC.  The present explanation, as examplified by the Elsberry paper, is the molecular clock idea.  That is that all these vastly different species share the same constant mutation rate in cyto C.  This is pure fancy.  As I said earlier in this thread, the clock is proven invalid now.  So, essentially, we dont presently have any explanation for the equal distance phenomenon, which plainly means that the present theory is inadequate.

Plants and animals show equal distance to yeasts in Cyt C? I doubt it, though I may be wrong.
And why do you think insects, fishes and human should have different distances to yeasts in this protein? What are your arguments?
If you can explain this observation with another hypothesis, can you share your insight with us? You were talking about a distance not increasing between lineages but set from the beginning. Could you be more precise?

You state that the molecular clock has been proved wrong, in a sense I agree. The molecular clock is not applicable in lots of cases (conserved domains in proteins come immediately to mind), but this doesn't imply that it's not applicable to neutral susbstitutions.

Well, I'm afraid you have not convinced me (yet), Shi.

You haven't provided any clair evidence of a comparable identity between human-yeasts and bacteria (which was the ground of your argumentation). You have not adressed Russel's critiques on your argument.
And even if true, you know, Shi, that the divergence between eubacteria and mitochondria began long before the separation between fungi and animals. Not to mention the divergence between protostomia (insects, molluscs...) and deuterostomia (vertebrates...), that you were taking as example, which is even more recent. Think about it and realize that most of the difference between human-yeasts and bacteria in cyt C accumulated in the common ancestors of animals and fungi, not in their two lineages separately. Moreover, this is considering our lineage only because, we don't know (AFAIK) the amount of mutations that accumulated between the common ancestor of bacteria-mitochondria, and modern bacteria in Cyt C. Maybe it's huge, maybe not. Maybe the ancestor was closer to our mitochondria, maybe it was closer to E. coli.

You know that the molecular clock does not apply in lots of cases, therefore it is not used for phylogenetic analysis anymore. The good old UPGMA is obsolete. We don't use distance matrix to build phylogenetic trees anymore.

Then you lead me to an article (the PNAS papper I suppose) where the evolution rate of different genes is discussed. (Note that I took the time to read the summary.) So you believe it rules out the molecular clock hypothesis for all genes? The molecular clock is not a requirement of Neodarwinism anyway...
So you assert that the molecular clock hypothesis is wrong in all possible cases--without telling us why--whereas your haven't provided any coherent explanation of the pattern you described in Cyt C.

Shi, if you can produce an alternative scientific theory for evolution, we sure like to hear about it. But for know, your arguments against the current theory are rather unclear, to say the least.

But have you wondered why no textbook is saying anything about the second thesis of Darwin being also vindicated by the sequence data.  The second presentation of the same data set is the molecular equidistance phenomenon: human, rat, frogs, and fish are all equally related to yeast.  You will not find this presentation in any mainstream textbooks.  

You can do the test your self.  Ask people to answer a simple question such as: given orangutan being the common ancestor of both human and chimp, which is more related to orangutan, human or chimp, or are they equally related?  Most people would say chimp is more related to orangutan because they look more similar.  But they are wrong, human and chimp are equally related to orangutan.  You can also ask them, is frog more related to fish than human is?  They would say yes and be wrong.  Human and frog are equally related to fish.

If you do such a test, I believe 99% of non-specialists would fail the test.  It is also clear from this thread.  People like Russell seems to know a lot about evolution and is clearly a biologist but in fact knows little about the equidistance phenomenon.  

This is what I mean that most biologists are casual believers of evolution (including myself for 25 years before I decided to truly know something about evolution).  They only know the story that is selectively presented to them by the specialists.  To truly know something, you need to know both the plus and minus side of it.  You need to know that while the specialists are touting the clock in books for the layman, the same specialists are calling the clock a mirage in specialist journals.

(Shi, we told you that distance is not used to infer phylogenies anymore.)

Of course human, rats, frogs, and fishes are all equally related to yeasts, these animals all have the same common ancestor with fungi. You find it in any book about phylogeny.

And your last examples are just wrong. Orangutan is the ancestor of nothing, human and chimp are not equally related to orangutan (in fact, chimps are closer to us than they are to gorillas). You are wrong again regarding frogs and fishes.

Oh yeah? This looks like a pretty strong claim at first sight, but it's not very meaningful without a clear way to quantify both genetic and phenotypic similarity. Sequence matching and cladistic analysis come to mind. Can you name two living species which are "vastly different" phenotypically, and "nearly identical" genetically?

My apologies for the dodgy quoting. Could somebody spare me a clue?

Well, his claim could be true, since most genes used in phylogenetic studies don't control morphology.
Anyway, I don't see how it contradicts the theory of evolution.
It would tend to rule out the current models of gene expression (traduction in proteins and so on). Thus it could as well contradict common design or prescribed evolution.

If I understand correctly, Shi, we have the same problem.
You regret that a simplistic vision of evolution is still dominant among believers in the theory, even biologists. Most of them only see living beings as more 'primitive' or more 'evolved', which leads them to wrong conceptions: the primitive should be closely related to each others, and the evolved 'advanced' species should belong to different groups.
Well, it's our job to change this old vision of life, but we'll rely on the current theory of evolution for that.

Edmund,
The clock idea is based on the assumption that two species split with nearly identical sequences and accumulate mutations gradually.  Based on this assumption, the whole field of clock is built. Under such assumptions, the odds of no clock may be zero, as you may calculate.  But what if this assumption is wrong?

It's not wrong, from the evidence we have.
See in a recent article in Nature: two fish species (Amphilophus citrinellus and A. zaoliosus) recently diverged in a crater lake (Lake apoyo). Basically, the genetic distance between both species in the lake is less than the distance they show with populations of A. citrinellus living outside the lake.
I assume you know how to interpret a haplotype tree.
 
You have a comparable genetic situation in the polar bear and the brown bear.

Biologists Are Not Design Experts

Biologists are not design experts. In fact no scientists are design experts. Engineers are design experts. The crew at Panda’s Thumb ought to follow their own advice and step aside where they have no expertise. Complex specified information is digitally encoded along the spine of the DNA molecule. Are biologists information experts? Nope. Information science is a branch of mathematics. Evolutionary biologists should stick to putting the phylogenetic tree in the proper order. Lord knows they still have their work cut out for them with just that.
Filed under: Intelligent Design — DaveScot @ 10:52 pm


I guess DaveScot thinks that the only thing biologists do is taxonomy.

Of course BIOLOGISTS ARE EXPERTS in detecting design. They are experts in detecting the design of evolution. They are quite adept at detecting the signs of evolution and hence would be experts of detecting whether or not something is the result of evolution or not.

Well, everything in life is the result of evolution. Some biologists discuss the results of natural selection (adaptations). This is not the same thing.

Shi,

The example I provided involves two true species, not varieties or subspecies. In fact, all the studied models of speciation show a high genetic identity between the new species (in gene sequences) according to the molecular clock, and rely on random mutations, drift and selection.

However, you suggest that sometimes, a major instant split creating very different species could occure.
Your hypothesis would rely on unknown mechanisms (genetic remodeling...). I have a few questions about it.
When should this process take place? When two genera split ? Or two families, orders, classes, phyla, reigns? Would this process have different magnitudes depending on the phenotypic changes that are needed in order to create a new phyla vs a new genus?
For example, do you think that birds or mammals originated in a single major mutational event, or several?
You also imply that humans were... designed by this unknown process. Could you be more precise regarding the species involved: do you think all human species (H. habilis, erectus, ergaster, neanderthalensis, sapiens) and pre-humans (Saelanthropus, Ausrtalopithecus...) appeared this way, or did some of them appear through the known speciation process? You know that the difference between H. neanderthalensis and H. sapiens is more subtle than the difference between the two fishes above.

All the evidence of evolution presented in scientific papers are merely cases of micro evo.
Please define micro evo, speciation has been observed in the wild and in the lab, and advances in molecular biology help us to understand how larger jumps have occured, ape to man is not really much of a problem anymore. You're right it is not fair to dismiss the claims of intelligent people without hearing them out, luckily the claims of the ID movement are ludicrous. Many people have examined the claims of Dembski Behe et al and found them to be utterly without merit, so it is not fair to say we insult their intelligence by ignoring them.

AFAIK, there is no evidence of "larger jumps" in the evolution of life, if by "jumps" you mean changes occurring in one generation.
Evolution can be very fast sometimes, but it's not instant (one generation), except maybe the well understood process of speciation via hybridization and polyploidy.

For Shi,
The gaps in the fossil record are not evidence of evolutionary "jumps", and Gould & Eldredge never mentioned such processes. They refer to fast evolution associated with speciation events (which is self-evident since fossil species are defined by their morphology).
The two fish species I showed would probably support the punctuated equilibria if we only got fossils.

People keep touting the lack of transitional forms as an evidence against evolution. They should know that maybe one fifth (my estimation) of the 2 million identified species are fossils. Since they existed for at least 3 billions years, we've identified only a fraction (1/10,000?) of the billions of extinct species that existed.

All around us, we see beautifully adapted things, yet we envision a time when there were barely motile flagella and 7% wings. Wouldn't that be a funny world, if we could go back in time?
You can see a funny world now. What you think is perfectly adapted could also be seen as imperfections. Talking about wings, have a look : http://www.nature.ca/calendar/images/m_marmota_monax_p186_250.jpg Does it have completely formed wings? Is it perferctly adapted? Well nobody can tell. If it comes to disappear, as too many species do nowadays, that means it wasn't so well adapted afer all. Adaptation is relative, the environment (Nature if you want) selects the working forms, that doesn't means they are perfect.
Quote

You speak of parts A, B, and C evolving together, so that the subsequent removal of one part would of course cause nonfunction. But all this is speculation until we can understand systems closely enough to know if it is plausible.
Protein coevolution is a well known phenomenon in phylogenetics. A mutation occuring in one subunit of a protein complex is followed by mutations in the other subunits. This pattern of evolution can be detected nowadays. Here is an article I just got after googling "protein coevolution" http://rana.lbl.gov/papers/Fraser_PNAS_2004.pdf

So I didn't get a clear answer on the chromosome question. Apparently if there are different chromosome numbers, hybridization is possible, as in horse and donkey. But hybrids aren't viable.
That's not always the case. AFAIK, within some species (the mouse, I think) you can have different karyotypes between reproducing individuals. It even happens in humans. IIRC, there is a case where one chromosome 21 is fused with one chromosome 15. After the "digestion" of the separate 21th chromosome in the gametogeneis or meiosis, the zygote can inherit from one parent, the fused chromosome (15-21) with no separate chromosome 21, and a normal gamete from its other parent. Thus, the zygote gets a odd number of chromosomes (only on chromosome in the 21st pair + one fused chromosome in the 15th pair) but the child will be completely viable and normal. You can imagine that in one population, this fused chromosome becomes dominant (for some reasons), resulting in a human population having 44 chromosomes.
Quote

And I am wondering how the chromosome number change happens in the first place. If there is a fusion of two, it must occur during one meiosis.
I'm not sure that it has to occur there. It could occur somewhere in the gametogenesis.
Quote

How does a chromosome know how to fuse itself with another and come out with a beautiful and coherent result?
Beautiful... it happens to be viable that's all. If it doesn't work it's lethal. Nobody can claim that the chromosome fusion in Homo sapiens has anything to do with our adaptation.

I'm leaving the religious questions to others.  ;)

To find human and fish are equally related to another fish in genotypes is unexpected for Darwin, for Mayr, for me, and for 99% of casual believers of the theory.
I'm not sufficiently knowledgeable about taxonomy and phylogenetics to be sure that there aren't different lineages of fish that diverged before one of those lineages split off our ancestors.

You're absolutely right Russel. And the fossils confirm the molecular data. chondrichtyans (sharks...) and osteichtyans (other fishes) diverged before actinopterygians and sarcopterygians (us) split.

I doubt that Mayr haven't considered that ; and casual believers in the theory have to open their minds and stop considering basic shape only.

I don't get your logic Shi, the molecular clock is just the description of an observed pattern. It's not a process. The biological process is mutations + natural selection. Mutations are random, so on average they're expected to happen at a regular timescale (depending also on the generation time). If almost none of them are beneficious, but neutral or deleterious (no positive selection), a molecular clock pattern is expected in DNA or protein sequences.
It works in a lot of cases where it doesn't have any particular reason not to do so, and sometimes it doesn't works (probably because of selective pressure).
So you consider this observation and assert that, since a molecular clock pattern is not observed in some cases, the other cases where it is falsify Neodarwinism. (???)
You'll have to clarify your reasoning here.

The genetic distance between sharks, troots and human may have been surprising for some that didn't think enough about the expected data. They had no reason to think that the lineage leading to human should have accumulated more mutations in Cyt C. Or they didn't consider the paleontological data. Yet, anthropocentrism still influences us.  :(

EDIT: I'm pretty sure that cladistic analysis on morphological data produced the correct topology regarding fishes and tetrapods. So the molecular phylogeny certainly wasn't a suprise for experts in cladistics.

Russell,
Then, perhaps you can enlighten me why human, rats, frogs, and fish are all equally related to yeast, given that these different species all are proven to have different rates of mutations. If you cannot, then perhaps you can explain why it does not falsify the current theory.
I, and others have tried, repeatedly. Here. Let's give it one more go.

Humans, rats, frogs and fish diverged from one another - and developed their different rates of mutations - at some point in the last relatively short period of time, before which they shared a common ancestor that had already diverged so far from yeast as to retain only the minimal sequence resemblance dictated by the functional demands of the gene products. I expect any truly neutral sequence inherited from an ancestor common to both yeast and humans to be long since scrambled to complete randomness - i.e. unrecognizability.

Do you expect your great-great-grandfather's DNA to be measurably less divergent from a chimp's than your own?

Yes Shi, what about the genetic distances between humans, rats and frogs, compared to their distance between fungi?  That should give you some valuable information.

Does current research indicate any possible function for non-coding DNA. One might expect redundant DNA to be lost over time, but not only is it retained but the sequences are highly conserved.

Some non coding regions have a structural role, especially near the centromere, AFAIK.
Evolution does not predict the reduction of size for non-coding DNA, otherwise it wouldn’t exist. In fact, an important proportion of non-coding DNA is made of transposable elements, which replicate themselves in genomes, like parasites. Transposable elements represent 70% of the maize genome for instance. This is a case of selfish gene that can increase its fitness (replication rate) without (apparently) increasing the fitness of its owner. This clearly does not support Intelligent Design.

Author: jeannot
Generally, non-coding DNA is not so stable in amount or sequence, AFAIK. I remember the case of the fugu fish (I think) that seem to have lost a large amount of its non-coding DNA. Also, the amount of non-coding DNA in prokaryotes is rather low.
And non-coding sequences have a high mutation rate.
Also, some junk DNA is the result of genome duplications (common in plants) followed by gene silencing. The variation in genome size among angiosperms is pretty huge.

“Parasitic DNA” cannot expand indefinitely since it would certainly reduce the fitness of its owner at some point. Then you might ask “so, even a low level of transposable elements in a genome can be counter adaptive?”. It could be, but sometimes transposable elements can be adaptive; some of them carry resistance genes. Barbara Mclintock (Nobel price in the 80’s) demonstrated that transposable elements in maize are “activated” by abiotic stress. (I’m not an expert on this subject.)
Also, remember that transposable elements derive from viruses (and vice versa), so maybe they can move from “host” to host and replicate inside genomes even if their replications are counter adaptive for their hosts.
Actually, transposable elements cannot exactly be qualified as non-coding DNA, since they can be “activated”, but I think some of them can be completely deactivated at some point.

This comparison cannot be made with a new born because you can’t begin with “I am a conscious new born”.

Using an in silico representation of the metabolic network of Escherichia coli, we examine the role of contingency by repeatedly simulating the successive loss of genes while controlling for the environment. The minimal networks that result are variable in both gene content and number. Partially different metabolisms can thus evolve owing to contingency alone. The simulation outcomes do preserve a core metabolism, however, which is over-represented in strict intracellular bacteria. Moreover, differences between minimal networks based on lifestyle are predictable: by simulating their respective environmental conditions, we can model evolution of the gene content in Buchnera aphidicola and Wigglesworthia glossinidia with over 80% accuracy. We conclude that, at least for the particular cases considered here, gene content of an organism can be predicted with knowledge of its distant ancestors and its current lifestyle.

What IDers must understand is that evolutionary biology doesn't make future predictions (except at a short timescale). First, they would be useless since they cannot be verified within a researcher's lifetime. Second, as J. G. said, there is far more than one evolutionary path for a given lineage. Third, we cannot predict future selective pressures (environments).

However evolutionary biology produces predictions on what we can observe or detect, like transitional fossiles, the origin of Homo in Africa (Darwin's prediction), phylogenetic trees, the trace of a chromosomal fusion in Homo...

The selective pressures I mentioned rely on the selected traits, since these traits could not be predicted, these selective pressures cannot either, even if we know the precise selecting environments (which we don't).

The concergence between certain eutherians and maruspials is nowhere near incredible. This is just rough morphology, like the wings of a bat and a pterosaur. The anatomy is quite different.

I could speculate, but I am clueless. Actually, I threw the question out there but I haven't read up on the genetic similarities. I'd like to know more about that.
We don't know any particular genetic similarity between convergent marsupials and eutherians. First, we have to identify the genes responsible for a given morphology. But since these genes interact and co-evolve with others, we don't expect any genetic similarity between analogous forms.

I guess I would lean to the idea that those animals were not really separated for as long as we think they were. and yet, they've got this completely different reproductive strategy.
They were indeed separated a long time ago and we have a remarkable convergence. Yet, this is rather common in animals and even in plants.

So basically because "homosexuality" exists it must be due to an evolutionary pathway?  We just make this assumption because...?  Even though it seems, on its face, to contradict evolution?

Why do you conclude that?

Because homosexuality exists, we can go back through time and predict it, like any fact or event. The evolutionary pathway is your own interpretation.

Davetard doesn't think the life we see here on earth began here?
He's neither the smartest guy nor the dumbest guy to entertain that notion. Read Francis Crick's "Life Itself".  Conceivably, the planet was seeded - either intentionally (yes, space aliens) or accidentally - by hardy spores that arose from a start somewhere else. Unfortunately for Dave, moving the origin to a different place and time doesn't make Intelligent Design any more sensible.

But the fact that life got all the way to cells with DNA, ribosomes, genetic code, hundreds of coordinated metabolic pathways presumably associated with the bacteria-like creatures dated to within a 1B years from the planet's origin - including a lot of what must have been pretty inhospitable years - has caused some sane people to speculate on the possibility it got a jump-start from a lineage that had more time at its disposal.

Scientists can only speculate about the probabiliy of evolution of the first life forms on Earth, since they don't know much about the environments, mutation rates and generation times (which may have been as short as a few seconds) of the first replicators.
And most important, no one can compare this probability (which we don't know) with the likelihood of evolution of life in space. (I'm not even considering the seedings by aliens).

I'm disappointed to see that Crick's big numbers tend to look like Dembski's maths. I even saw once his calculations beeing taken as example by a "rational creationist". ???

This whole argument about the conservation of information, or that evolution cannot increase information is just full of sh**.

Life as nothing to do with information intrinsically, because information is only relevant to an observer. It doesn't mean anything on its own. I've never seen any biology textbook discussing information.

You have several identical replicators. A mutation occures in of them, which increases its replication rate. Therefore this mutation is selected. If the increase depends on the environment, this can lead to different types of replicators.
Wether that increases or decreases information entropy or whatever is just intellectual masturbation of pseudo-scientists like Dembski in order to fool the ignorant or the skeptic.
Needless to say that none of them has been able to point a specific evolutionnary process that should be impossible, according to their law of 'conservation of information'.

From the IDEA site: intelligent design theory is not merely a negative argument against evolution. Intelligent design begins with positive predictions based upon our observational experience of how intelligent designers operates.
What are these predictions besides "things are expected to look designed"? And most important, what predictions does ID make that can falsify its hypothesis? Can it predict things that cannot have been designed?
And don't you understand that the argument of comparison cannot scientific? Following such comparison, every ecosystem, snowflake, planet... must have be specifically designed. Do you think that plate tectonics was designed?

Darwin's argument for natural selection was an argument from ignorance, because he was so utterly ignorant of what he was dealing with.

WHAT? Have you read his book?
When the current theory about the origin of species was just "poof" (like ID), do you think that a verbal model based on evidence and able to produce predictions was an argument from ignorance?
Quote

Darwin justified the theory not because he could make observable predictions in the laboratory – after all he was trying to reconstruct the distant past – instead he justified it because it provided a better explanation of the evidenced than the main competitor hypothesis, and that’s precisely how the theory of intelligent design is formed, framed, and justified.
In which way is ID different from the old argument from Paley?
I'm sorry, CSI and IC don't constitute a theory, they don't explain why things are what they are, unless you're satisfied with "poof".
Quote

We argue that our theory provides a better explanation of some of the critical pieces of evidence of biology, namely the irreducibly complex molecular machines and circuits that we seen in cells and the presence of this informational software that drives everything in the cell as it’s embedded in the DNA molecule.
This argument from comparison is useless, see above. And BTW, the genome is not a program. Is was not written before its execution, and the the genetic code is part of the genome (as if the programming language was part of the program).

Genetic shuffling during meiosis? It was not meant as an argument for CSI, just as something pretty impressive, hard to imagine it evolving via luck.

"Because homology implies community of descent from...a common ancestor it might be thought that genetics would proovide the key to the problem of homology. This is where the worst shock of all is encountered...[because] characters controlled by identical genes are not necessarily homologous...[and] homologous structures need not be controlled by identical genes."
A gene is not a phenotype. If you change its environment, the same gene can produce very different traits. A gene alone is meaningless, this is just a random string of symbols. Nothing in the gene for insulin says 'this is gene for a 7 amino acid peptide designed for the regulation of glycemy'... nothing.
Quote

   * If evolutionists agree that there are other possibilities for the origin of homologies than common descent, then they should also agree with us that this makes the use of homologies as evidence of common descent null and void, since homology can be just as much evidence of other mechanisms.
There is a term for homologies that are not inherited from a common ancestor. These are called 'homoplasies' and have been a parameter in phylogenetics for decades.
Quote

   * The idea that the same set of beneficial mutations can occur randomly twice is astronomically low.
Who said that an homoplasy should be caused by the same set of mutations in two lineages? Do you think that wing developments in birds and bats are based on the same mutations?
Quote

First of all, the chances of getting one beneficial mutation is astronomically low.

Every drug resistance, adaptation to abiotic stress... that have been observed in the lab and in the wild are the results of beneficial mutations.
Quote

The chances of finding a sequence from point A to point B with all containing beneficial or at least non-lethal configurations is astronomically low.

This calculation is flawed because the mutations don't have to happen simultaneously or to follow a singe pathway. Anf most important mutations don't have any direction to follow. '... to point B' is just meaningless. I know you consider yourself as the product of a purpose, but I'm afraid you are not.

It seems to me that science once again is playing politics.

Eugenics WAS an branch of science, rather popular before World war II and nazism.
Now eugenics is a thing of the past. There is no research in this field.

Yes, I just mean that two pieces of double stranded DNA will line up to preserve the 3'-5' direction. I think AiGs argument was that if the chromosomes joined up face to face half of the new chromosome would run in the opposite direction and the codons would be backwards. I was just pointing out this wouldn't happen.

I think we’re not talking of the same thing. Yes, transcription can only occur in the 5’ -> 3’ direction. But as far as I understand, AfDave was not referring to that. He was unconsciously implying that there was one definite master strand for a whole chromatid, since all genes were supposed to be read in the same direction, for some odd reason. If it were an absolute rule, the way chromosomes join would matter a lot. They would have to fuse both master strand and coding strand with their analogues, and not a master strand with a coding strand.
The fact that DNA has two strands in both direction doesn’t change anything.

Is the issue that individual codons can be in either DNA strand as once the strands are unwound the RNA polymerase attaches to whichever strand is the master at that point, so it would not matter which way chromosomes fused as it is individual codons that are transcribed, and which strand is the master can swap from codon to codon?

I'm not sure about the question (your sentence is a bit too complicated for me), but for one gene, there is one physical master strand.
Of course, in a chromatid, different genes can have different master strands (that is they are read in different directions).

I hope it helps.

Indeed, even if the RNA polymerase could transcript the complementary strand of a given gene backward (it can't because this strand lacks a promoter) the resulting mRNA, if translated, would be completely different. Just try it on a piece of paper and see.

And the polymerase can't swap the strands during transcription, they are oriented in opposite directions ( 5'-3' ) (and certainly for other biochemical reasons).
A gene or an operon is read all in once (not sure of the expression). If the polymerase fails before the end, it has to start again from the beginning.

It's always important. Replication and transcrition only occurs by 'reading' the master strand from 3' to 5' (therefore, DNA and RNA are synthetised in the opposite direction 5' -> 3';).

In a (possibly vain) attempt to prove I am not quite as stupid as my few earlier posts might indicate:

My main error was to confuse codon (which I did know - but forgot when posting - refers to a triplet of nucleotides coding for a particular amino-acid) with gene (meaning that  to indicate a nucleotide sequence staring with a promoter, containing exons and introns, finishing with a stopcode, that is transcribed by mRNA polymerase to produce mRNA,, which, after any necessary snipping out of introns, becomes the template for the translation of the encoded sequence into a particular protein.)

Very simplistically, then, could one imagine genes as extension leads with a 5' plug and 3' socket. Imagine  two leads of identical length laid out so each plug is next to each socket and twist  together, and pairs of leads can then be joined to extend the line infinitely, plug connecting to socket, socket to plug. The process can be carried on infinitely. Take one pair of leads, unplug both pairs of  leads, reverse (flip over end to end) the pair of leads by swapping the ends over and reconnect, no problem. Imagine one lead of the pair is blue and the other red, blue represents the coding or master strand of DNA and red the complement. Flipping one pair of leads means instead of a continuum of red and blue leads there will be a section where red plug connects to blue socket etc and the two runs of connected leads will have one section of lead of the opposite colour. When the particular gene is unwound to be transcribed the mRNA polymerase will attach as indicated by the promoter so will automatically find the coding strand and read off in the right direction. So in a chromosome, is the coding strand continuous or can it alternate from one individual gene to individual gene?

Tom Ames' link  seems to indicate this is so for yeast at least.

(Ducks head under parapet hoping not to appear even more stupid!;)

Ok, I didn't get what you meant by the RNA poly using different strands between two codons.

But you're not reading. ;)

Since the chromosomes are always ‘read’ in the same direction, this means that the same ‘sentence’ would be read backwards, and would make no biochemical sense!

If a chromosome fragment cannot be read backward, how could two chromsomes fuse head to head?

Several flaws here.
- Thanks to sexual reproduction and recombination, mutations don’t have to be ‘fixed’ at each generation (which is a nonsense), but can occur in different genomes.
- The divergence between chimps and human occurred 15 My ago, IIRC.
- Most mutations are neutral

But seriously, I think that the molecular evidence favors the more recent date, and my (American!;)) paleontologist friend says he's comfortable with that, too.

Molecular datation can't contradict geological datation. It is calibrated from geological datation (fossils or other biogeographical data).
About Sahelanthropus tchadensis:
Quote
The search for the earliest fossil evidence of the human lineage has been concentrated in East Africa. Here we report the discovery of six hominid specimens from Chad, central Africa, 2,500 km from the East African Rift Valley. The fossils include a nearly complete cranium and fragmentary lower jaws. The associated fauna suggest the fossils are between 6 and 7 million years old.

It doesn't confirm the 10 Mya, but if their datation is correct, -6 Mya is the upper limit regarding the split between our lineage and chimps.

Well, being evolved is not a scientific attribute. We don’t have any measure for that. All currently living lineages have evolved for the same exact time. Maybe some have undergone more mutations, maybe some have undergone more phenotypic changes… This is moot. The fittest in its environment reproduce more efficiently, that’s all we have to know.

Well, here are my answers to your questions BWE.

Brittany (where I live) is an old mountain chain, the Armorican mountains. It's the result of the Hercynian (or was it Caledonian?) orogenesis which occurred during the Paleozoic era. Since then, it has been eroded to its impressive 400 m of maximum altitude.

Fossils: well not much since this is a granitic region, but during that timescale (from Paleozoic to present), a lot of species lived and died.

Species live in a particular places for:
- Ecological reasons: they are fit to a particular niche (habitat, resource, other species) that prevents their migration where it doesn't exist. That's why, if a climate change induces a displacement of their optimal habitat, their individuals that migrate in the correct direction are selected (habitat tracking) therefor a hole biota migrates.
- Historical reasons (seed dispersion, accidents, speciation events...)
(this is a very incomplete answer, it would require a whole book)

A top-level predator regulates its preys which themselves affect the lower levels of the trophic chain and so on. Therefore they are often considered as "key species".

Scientists think dinosaurs existed because they have found fossils. The time required for fossilization and sedimentation is important. Absolute dating by radionuclides confirms this.

Ridges and trenches in the ocean are caused by tectonic plates divergence and subduction.

Mollusks and echinoderms belong to very different groups. Mollusks are protostomian and echinoderms are deuterostomian. But within each group, taxa share ancestral traits, like the balstopore evolving into the mouth or the anus.

The magnetic orientation of some sediments indicates the direction of the magnetic poles, which are frequently inverted. (I think)

You guys are the biology experts ... you should know this.

No, the gene we are discussing is not part of the DNA that IBM researchers have studied. In fact, most of our DNA, contrary to GLO, doesn't show any recognizable genic structure. But it can have a structural function for instance.

And we are aware of the latest discoveries before you, Dave.
However, I would point that there isn't any evidence yet for a biological function in the patterns recently discovered by IBM scientists. Even if it were, it wouldn't contradict evolution in the slightest.

But if you want a proof of common descent, I suggest you google "endosymbiosis" and "nucleomorph" or even "buchnera". (An evidence that is not discussed at talkorigins, afaik.).
Of course, it requires some basic knowledge in biology and doesn't falsify common design (nothing can).

Is it not just as plausible that both ape and human GLO "broke" independently?   So I think the following possibilities exist ...
(1) Pseudo-GLO is NOT "broken GLO" and is found throughout the animal kingdom (either ubiquitously, randomly, or in nested hierarchies).  This type of scenario, where a species has a functional gene and a pseudogene is not uncommon.
You’ll have to explain why the species that carry a pseudo-GLO gene are the ones that can’t synthesize vitamin C. Coincidence?
 
Quote

(2) Pseudo-GLO IS "broken GLO" and is only found in species unable to synthesize vitamin C ... this is because the gene "broke" in the ape-like ancestor, then this "broken gene" was copied throughout the evolutionary path to humans.  If this is true, however, you would still need to explain how the gene broke independently in the guinea pig ancestor, but wound up in modern guinea pigs looking "36% similar" to modern human pseudo-GLO.  You have the problem of the appearance that humans are more closely related to guinea pigs than to the pro-simians! (who have functional GLO)
The 36% similarity is in fact a powerful evidence for common descent, given that the absolute minimal level of similarity is 25 %. 36 % is extremely low, and proves that this pseudogene is not subject to stabilizing selection. What is the similarity between human and other apes, out of curiosity?
 
Quote

(3) Pseudo-GLO IS "broken GLO" and is only found in species unable to synthesize vitamin C ... this is because all animals were designed with a functional gene, but now some have independently lost function because of mutations.
Hundreds of primate species losing a gene function independently with the same mutations? Do you know the concept of parsimony?

They use the term 'lesions' instead of 'nucleotids', which is misleading since most of the homologies are not due to convergent mutations (lesions), but common ancestry.

Anyway, I fail to get their logic. Even if  '36% of identical lesions' were the correct expression, their tree clearly supports common descent : human and other apes belong to a clade where similarities between taxa are far higher than 36%.

EDIT : I didn't notice the question marks after the apes names. But I'm pretty sure that the tree built with GLO will look the like this.

Agree with what, Dave? that 36% of the point mutations in the two broken genes are the same? Sure, we agree. Now, will you read our answers, and the links we gave you?

It would be more accurate to use the term 'nucleotids' instead of 'mutations', because mutations are changes of ancestral states. 36% of similar point mutations would imply that 36% of the changes in GLO since the human and rodent lineages split are convergent, which is not the case(I'm sure the percentage is just the basic distance between the genes).

So Dave, since 36% of similarity between the broken GLO genes in guinea pigs and human are very low and support our view, what is your interpretation?

I think they are also pointing out that evolutionists agree that guinea pig GLO broke independently from the simian line, so why shouldn't we expect ape GLO to break independently from human GLO?

We should.  At the very least, we cannot dogmatically say that the GLO gene definitely broke in the common ancestor, then was copied to apes and humans.

Do you agree?

No.
We use the principle of parsimony. All copies of the GLO gene are broken in the same way in primates, which besides were known to share a common ancestor way before (that's why they constitute an order).The pylogeny (tree) made with that pseudogene reflects the phylogenies based on other coding genes.
Parallel loss of function, resulting from the same mutations, are extremely improbable. Do you know how many primate species exist?
And the pattern of mutations confirms, alongside the fact that those organisms can't survive without vitamin C, that GLO is not coding and evolves by genetic drift, not NS.

According to common design, the creator would have put broken copies of a gene in each species, copies that reflect the current phylogeny, built with coding genes. Why would he? A broken gene is not part of a design, it's useless.

You said you would readily accept any evidence for common descent. I don't think you are sincere. What kind of proof would convince you?

And what are your thoughts on the fact that AIG only referred to the 36% homology between guinea pigs and humans, but forgot to mention the 97% identity between us and chimpanzees? Silly mistake again?

mmm actually, I spoke too fast. :O
Faid, you were right.
There indeed seems to be a convergence between human and guinea pig for some substitutions in GLO. I should have read your post, and the abstract that Russel provided more carefully.        
Quote
A comparison of the remaining human exon sequences with the corresponding sequences of the guinea pig nonfunctional GULO gene revealed that the same substitutions from rats to both species occurred at a large number of nucleotide positions.

I don't have access to this paper, but to another by one of the authors.

I'm not an expert in molecular biology, but these 36% of convergence are not very disturbing. Convergence increases to a value of 25% as mutations accumulate. Some mutational 'hot spots' (I don't know much about them) may account for the difference.
Anyway, the percentage of identical substitutions between human and chimp is certainly well above 36%.

However, their sentence puzzles me: "from rats to both species occurred... ". Since when are modern rats the ancestors of primates and other rodents?
That could be misleading. One must not consider that GLO in rats is the ancestral state of the borken copies in guinea pigs and primates. The 36% of convergent substitutions might be an overestimation. Some neutral substitutions may have occurred in the rats lineage only.
EDIT : I already see IDers coming. For every gene showing some convergence between lineages (and there are several) they'll be claming "See? Darwinism is doomed, this one gene contradicts comon descent, ah ah...ect." ???

I suspect that's exactly the problem.

I don't have access to the paper, either. But I do have access to GeneBank. What do you want to bet that most of that 36% will turn out to be rat-specific mutations from the consensus?

I won't bet because that's what I think too (except for the "most"). In fact, I edited my post in that way just before I read yours.  ;)

To check that, we should gather several sequences from rodents, primates (and maybe other mammals), if available, and build a maximum likelihood our parsimony phylogeny. The three sequences alone (rat, guinea pig and human) won't do.
But the number of mutations is expected to be much higher in the broken genes, so I don't expect the level of convergence to be much reduced.

Maybe we could write a paper together?  ;)

That's what Inai et al. measured. The substitutions between rats and guinea pigs (not from rat to guinea pigs, and that's their mistake), which they compared to rat-human substitutions, necessarily occured after their lineages diverged.
The apparent convergence of 36% could be significantly reduced, only if several substitutions accumulated in the rat lineage only, which is not likely since the active GLO is subject to purifying selection.

I know, that's why I'm speaking of substitutions that do not affect the gene's function. Now, I think such are possible to occur (although much, much less than all the kinds of mutations that accumulate in broken genes, of course)... Otherwise, the GULO gene should be 100% identical in all animals that can make their own vit. C- And I think that is not the case? Or is it? Does anyone have a relevant source?

Did I mention that this is fun?  :)

Sure, synonymous mutations, for instance, are essentially neutral. You can also have some beneficial mutations.
And as you said, the number of neutral substitutions is far higher in a non-coding sequence, since 100% are neutral.

Indeed Russel, most of the mutations that seemed convergent between guinea pig and human are not, but are specific to the rat lineage. (I did a quick comparison using sequences from rat, pig, guinea pig, human and cow.)
In fact, this doesn't mean that evolution was faster in rats, since lots of mutations occured in the guinea pig lineage only (therefore are not shared with human). I should have thought of that.
In a segment of the gene, I counted 9 mutations in the rat lineage and 10 in the guinea pig lineage, after their divergence. A was expecting the latter to exceed to former by a higher margin. Maybe the loss of function of GULO in guinea pigs was rather recent, but still...

Now, the abstract you posted (Inai et al.) was actually misealding. They clearly imply (unconsciously?) that the gene copy in rats was the ancestor of the copies in humans and guinea pigs, which was a unwarranted assumption.

Dave, no one understand why you want GLO to be 100% identical between human and chimps, since that's precisely what evolution doesn't predict. This pseudogene is not selected, so it can freely accumulate mutations at a high rate.
But if you want a 100% identical gene between human and chimpanzee, I can find one for you. Would you take it?

PS:  I already posted the 97% homology between human and chimps in GLO. You could have said that a convincing evidence for common descent would be a 98% identity.  ;)

Dave, you don't seem to undestand what common descent really implies.

Only one mutation broke the gene function. After that, the pseudo-gene underwent a lot of mutations that could also have altered its function (deletions, stop codons), and most of them are shared by humans and chimps (and other apes).

I'm pretty sure the cytochrome c gene is exactly the same (all codons identical, not just the amino acids they code for) in humans and chimps.

mmm, not Cytochrome C... but I'm pretty sure that the mitochondrial 16 S rRNA gene (and all rRNA genes after all) is 100% identical between human and chimp.

Dave, imagine God designing apes and man. Ok, he would use the same tools (genes) with only slight differences (mutations) that happen to reflect a common ancestry because all primates look and work the same, but not exactly. For instance, chimps are closer to men in their design compared to gorillas and other apes.
You can hold that argumentation, but it falls as soon as the common features, which he is supposed to have used when designing his creatures, are useless.
Everything that has nothing to do with design (protein production) - third codon position, pseudogenes - reflect our common ancestry and confirms the current theory of evolution.
Moreover, why such neutral loci (loci=pieces of DNA), not subject to selection (typically, the third positions of codons), are more variable between species, as our theory predicts?
You could argue that, since these loci are not important for design, the designer placed them randomly in his creatures. Ok fine. But their distribution is not random actually. The non-coding (ie non-designing) features also reflect common ancestry.
The case of GULO is particularly striking.
You have to imagine that the designer decided to equipped primates with a broken gene (why put a broken gene instead of nothing?) having different errors that (tadaa!;) reflect common ancestry (ie Human closer to chimps than to macaques). And he is also supposed to have inserted a broken GULO in guinea pigs, but a very different copy, with BTW looks like the working gene in rats.  
Why in the world would he do that?
I await your explanation.

Dave, we can see you coming. You're about to argue "why don't you accept that the same mutations could have occurred independently in primates, since you admit some very improbable event (like the apparition of the first cell for example)".
But you argument is flawed.
To explain the apparition of the first cell for instance, we also have different hypothesis:
- it was the product of an extraordinary event. Creationists like Dembski believe this is our position. (???)
- Goddidit.
- it evolved from less complex life forms (our position).

You have several options:
- claim that common ancestry inferred from the mutations in GULO is in fact the product of an extraordinary chance. Most mutations are random, they may be some 'hot spots', but the probability for them to reflect the exact phylogeny built with dozen of gene is basically zero.
-  explain how common design predicted that the designer would place errors in GULO in several species, errors that reflect the phylogeny we can infer from working parts of genes.
- admit that mutations were inherited by different species from their ancestors, though genetic mechanisms known for decades.
- another hypothesis from your imagination.

Which one will you choose?

And if you're about to assert (like JAD) that all mutations are harmful, I'm afraid you don't have the knowledge to back up this argument.

1)  You assume that the ONLY reason human and ape GULO does not work is because of this single deletion.  Am I correct?
2)  You are assuming that pseudo-GULO is in fact "broken GULO".  Argystokes has not yet demonstrated that to me.  To me it is a possibility that "pseudo-GULO" has some as yet undiscovered function.  Remember the good old "vestigial" organs that turned out to have function after all?  Why wouldn't "vestigial" GULO turn out the same way?
Dave, scientists can demonstrate that a gene has lost its function. GULO lacks many portions (exons) in primates, it has STOP codons a different loci (signals that stop the translation) and the fast accumulation of mutations confirms this.      
Quote

4)  You assume that this "C deletion" occurring independently in apes and humans is a highly unlikely event.  Why is it so unlikely?  
The convergence for this deletion may not be unlikely, but primates share dozen mutations. And these mistakes in the broken GULO produce the same phylogeny built with other working genes. This cannot have happened by chance. Would you drop this argument?

A somewhat greater than expected proportion of those substitutions (36% observed vs. 25% expected) ...

For a given couple of mutations occurring independently in two lineages at the same locus, the expected convergence is indeed 25%. But the overall probability of convergence is much lower, considering the probability of occurrence of two mutations at the same locus, which is far lower than 25% if mutations are rare (recent divergence).
25% is the expected convergence, only if mutations are so frequent that the homology between two diverging sequences cannot be detected. (ie : 100% chance of mutating at the same nucleotide).

2. Of the remainder, what overall degree of convergence do we expect for neutral substitutions in the 75-million-plus years since the LCA between humans, rats and guinea pigs, and non-neutral substitutions since the gene "broke" in humans (~40 mya) and guinea pigs (?unknown?)?  How does this compare statistically to our revised estimate of convergence (i.e., after we have removed the rat-only substitutions)?

3. How would mutational "hot-spots" at some of these loci, if they occur, change our expected convergence in (2).

These questions are difficult to answer precisely.
It depends on the percentage of mutations per locus, which could be estmitated by: the number of mutations from an ancestral sequence / the length of the considered sequence (I guess).
To estimate the number of mutation that have accumulated since an initial split, you have to build a phylogeny using parcimony or likelihood.

But hot spots, and the possibility for a nucleotide to mutate more than once, further complicate calculations.

Evolution of an obligate social cheater to a superior cooperator

Francesca Fiegna1, Yuen-Tsu N. Yu1, Supriya V. Kadam1 and Gregory J. Velicer1

Top of page
Abstract
Obligate relationships have evolved many times and can be parasitic or mutualistic. Obligate organisms rely on others to survive and thus coevolve with their host or partner. An important but little explored question is whether obligate status is an evolutionarily terminal condition or whether obligate lineages can evolve back to an autonomous lifestyle. The bacterium Myxococcus xanthus survives starvation by the social development of spore-bearing fruiting bodies. Some M. xanthus genotypes defective at fruiting body development in isolation can nonetheless exploit proficient genotypes in chimaeric groups. Here we report an evolutionary transition from obligate dependence on an altruistic host to an autonomous mode of social cooperation. This restoration of social independence was caused by a single mutation of large effect that confers fitness superiority over both ancestral genotypes, including immunity from exploitation by the ancestral cheater. Thus, a temporary state of obligate cheating served as an evolutionary stepping-stone to a novel state of autonomous social dominance.

What is Jeannot referring to when she says "And these mistakes in the broken GULO produce the same phylogeny built with other working genes. This cannot have happened by chance." ??  Is she switching back to apes and humans, or is she still talking about humans vs. guinea pigs?

I was referring to primates, but you could add every mammals. Most of the "shared mutations" between us and guinea pigs are not mutations, actually, but ancestral nucleotide states that have not mutated in primates and guinea pigs, but in rats only. Humans and guinea pigs inherited them from their common ancestor, without modification.
But that doesn't means guinea pigs are closer to us than to rats. They share more 'mutations' with rats. Thus, a phylogeny built with GULO won't put primates and guina pigs in the same clade (group).
For the last time, you can't consider the loss of function alone as a valid evidence for common descent, because hundreds of mutations can break a gene.


And BTW, I'm not a female.

Dave, primates don’t share just one error in GULO. They share many errors; and each one could have broken the gene. They all lack, for instance the same exons. Since mutations appear one at a time, one mutation broke the gene (we don’t know witch one I think), and others freely accumulated after that. Some occurred in the common ancestor of all primates, some occurred only in hominideae (human and chimp) for instance.
Thus, primates don’t share all these mutations. What is particularly sticking is that the primates that share more errors are precisely the ones that were already known to be the closest, i.e. chimps and humans. Then comes others apes and monkeys, who share fewer errors with humans and chimps, as predicted by previous phylogenies.

No.  According to YEC theory, organisms were designed perfectly in the beginning.  The Creator then put a curse on all of nature to remind humans of sin and the need for a Saviour, and to remind us that this world is not our true home.  God will at a future time RE-create the heavens and the earth and they will once again be perfect.  Humans who choose to believe God will be with Him eternally in the newly created heavens and earth.  Those who do not will be eternally separated from Him.  Mutations are assumed by creationists to be a part of this "curse."

Dave, you're going to surpass our friend paley.  :)

So god decided to break GULO in all primates, and produce a nested hierachy of shared errors in this peudo-gene, which matches the phylogenies of perfectly designed working genes? Or did it just happen by chance?

I seem to recall that at least two other people said they were NOT claiming that all the breaks are the same.  I think what may be going on here is that you guys are saying that (1) both are broken and (2) they are 95% similar.  From this you conclude that the gene was broken in a supposed common ancestor, then transmitted along two separate lines of evolution.

Now what I am saying is this:  If both are broken and they are 95% similar ... big deal.  Fiestas are 95% similar to Aerostars and their alternators are also 95% similar, and guess what ... they are both susceptible to breaking ... maybe even in the same way!  But they share a Common Designer!  Ditto for Apes and Humans!b

Dave, how many times do we have to rehash this? I you don't want to hear, say it right now, it'll save us some time.

This is the LAST time, read my words carefully.

The data : primates can synthesize vitamin C and all they also have a broken copy GULO. Guinea pigs have also a broken GULO a can't live without vit C.
Now, since GULO wasn't broken in the common ancestor of primates and guinea pigs (otherwise, all rodents would need some vitamin C to survive), common descent predicts that it broke independently in primates and guinea pigs.
However it is highly probable that the gene broke in the common ancestor of primates. Do you know how many primates and mammals species there are? If you did, you could have calculated the probability for the inactivation of GULO in primates as a result of chance. This is, if I am correct : 1/the combination of (number of primate species) from (number of species that have GULO, ie at least all mammals). Think hard Dave, you can understand. If not, get a book on probabilities.
Guess what, this probability is ZERO, even excel can't give the precise result because the computer can't handle it.
Well, you could say it proves nothing and that a probability of a single event is meaningless. True, but primates were already known to share a common ancestor, before the GULO story. Think about it.

Anyway, if you still want to maintain that this is the result of chance, read the following. There are thousands of ways to beak a gene : insertions and deletions at any site, stop signals, etc.
As predicted, primates share lots of common 'errors' in GULO like the deletion of the same exons (portions of gene) by which they differ from guinea pigs.
However, mutations are not frequent (something like 10^-6 per site per generation), they can only happen one at a time in a given copy of a gene (in a gamete).
Hence, a gene inactivation is the consequence of only one mutational event, not two or ten simultaneous mutations. Can you follow this reasoning, Dave? Think hard, until you get it, then you may go on.
So, theory predicts that most detected 'errors' freely accumulated after the inactivation of the gene.
Thus, some mutations accumulated in the common ancestor of different primates species, and other occurred after their divergence (speciation), this process is the same regarding neutral mutations in working genes.
That's why we expect the nested hierarchy (phylogeny) based on errors in GULO to reflect the phylogenies built with data from other genes. [And we certainly don't expect chimps and humans to be 100% identical in GULO.]
Guess what? the prediction is verified. The probability of this observation resulting from independent mutations, is so small you can't even imagine. Not to mention that we have hundreds of peudogenes like GULO in our genome.

Now tell us your alternative. Common design of broken functions, God playing with us wicked primates?

Or if you don't understand, feel free to admit it.

And BTW Dave, a gene is nowhere near a car alternator. A gene doesn't do any job by itself, it's translated. Get a biology textbook, then try to express correct arguments, thanks.

Sir TJ - I don't take issue with anything you said. All I'm saying is that the definition of "species selection" as laid out in Wesley's piece:  
Quote
PE asserts "species selection" as the way in which major adaptive trends proceed. Closely related species are often likely to overlap in niche space (5 above). Ecological processes may cause the displacement and possible extinction of certain species due to competition with other species. If adaptive change in large populations is largely inhibited (6 above), then each species represents a "hypothesis" that is "tested" in competition. This is one of the more controversial points in PE.
doesn't seem incompatible with the H. neanderthalensis - H. sapiens story. I.e. are we talking about something deeper than semantics here?

I think we could consider species selection only if species fitness (which remains to be clearly defined) can produce better predictions than those based on inclusive fitness (allelic fitness). I don't think that is the case.
For instance, when the reproduction rate of a gene and the fitness of its bearer conflict, models and observations indicate that the former always outweigh the latter.
It's certainly the same regarding inclusive or individual fitness vs. species fitness. For instance, I study aphids, and lineages often become completely asexual. When there is no forst during winter, asexual forms are selected for their higher reproductive rate (they don't overwinter in eggs for three months, as sexually reproducing lineages do). So, you can very well imagine that, with global warming, these clonal lineages will outcompete the sexual ones. This would lead to the end of the initial species, since species can only be defined for interbreeding individuals. And of course, all these clonal lineages would be killed by the first winter frost.

Am I clear?

Quote (Russell @ May 25 2006,11:39)
This way of looking at it seems to make a clearer distinction between "species selection" and "individual selection", and you can sensibly distinguish between them. In the definition I quoted, I don't see the two as mutually exclusive.

I have seen this discussion framed as "what is the unit of selection: species or individual? And I think the answer to that is individual. But if the issue boils down to "what is a better predictor: the reproduction rate of a gene or the fitness of its bearer?" I would have thought that it would be the latter (which I would visualize as the reproduction rate of a combination of genes). But that's what actual data is for.

Well, the concept of species selection might work as well as indivual or gene selection most of the time. But what's important is to define a concept that always works
That's why this discussion arround the units of selection is completely on topic. If the real units of selection are closer to genes or individual, then there is no need of a 'species selection' concept. Lower level units are more suitable, because we can apply models based on 'harder sciences' (like biochemistry) to their evolution.
In fact, the concept of gene fitness would also be useless if we had the knowledge and computing power to apply equations from quantum mechanics to biology (I think that was Shrodinger's or Eisenberg's dream).

Inclusive fitness is a better predictor than individual fitness. Gene combinations are broken by sexual reproduction. And between two sexual generations, the fitness of any gene and the fitness of its bearer are indistinguishable (a perfect example is parthenogenesis in aphids during summer).
The reproductive rate of individuals can't account for observations like segregation distortion on chromosmes, male sterility and cytoplasmic incompatibilities caused by organelles, sterile castes in social insects (Darwin's big concern), etc.

To use technical terms, many lineages undergo stabilizing selection. According to Wright's adaptive landscapes theory, they've been occupying their 'top of hill' for millions of years, and the adaptive landscapes haven't been modified. Species are competitive in their own niches, and some of their descendants will significantly change only if they find a new vacant niche, in a speciation event.
For instance, tetrapods originated from fish when some had the opportunity to exploit the firm ground (is it the correct term?) in the Devonian, but there wasn't any reason why their ancestors couldn't fill their niches (marsh) anymore.
And of course, our ancestors have experienced the same amount of mutations, the genetic distance between sharks and trouts is greater than the distance between humans and trouts (got that AFDave?).

In fact, skeptic's objection is equivalent to "if we come from apes, why are there still apes?"

hat I'm really trying to say is that the process reduces down to chemistry.  All this talk about selective pressures, stabilizing seletion, yada yada must be impacting upon a physical process in the organism.

Of course, why do you think they can't?
That's precisely the strength of the current theory, it's completely compatible with other sciences. Do you think 'Goddidit' is? Is there a branch of quantum mechanics that explains miracles, like the apparition of Adam? Is God a scientific theory?
An organism is the result of the interaction genotype * environment, through a process of chemical reactions. Some organisms with particular genotypes can reproduce more efficiently than others in their environment. That is natural selection.
For instance, some mosquitos (Culex pipiens) can produce more offsprings in some areas because they have a point mutation in the gene coding for acetylcholine esterase. The mutated protein can't be inhibited by insecticides, it's been chemically tested.
Every selelected trait could be explained at the molecular level. It's just hard to do most of the time, because we have to identify the precise mutations and genes involved. Peacocks with longer tails have a better reproductive success, and even if we don't know which mutations affect the size of their tails, this doesn't mean that this trait could not be explained at the molecular level.

Author: jeannot
What happens at the molecular level is under environmental selective pressures. If you can simulate a whole population of organisms and their environment, using the equations of quantum mechanics, do it.
None can. That's why we rely on the theory of evolution.

For instance, the precise mutations and chemical pathways leading to the development of legs say nothing on why tetrapods appeared.

EDIT, I just saw your latest post. Glad to see we're reaching an agreement.
Quote
Random mutations would seem to favor chaos and in cases were there is no selective pressure and variations are generally equivilant shouldn't there be a more equal distribution within a population and not a bell curve?

What do you mean by chaos? Deleterious mutations are eliminated. Most neutral mutations have no effect on the phenotype of their bearers.
A more equal distribution... I can't tell since I don't know which variable you are referring to (allele, fitness, body size) ?

This is not correct, Tyranosaurus is not an ancestor of birds, but your message is clear.

Nevertheless this argument is not sufficient. You have to assume common descent first. A fossil alone doesn't prove that it is transitional.

Eric, you raise an interesting question.
LUCA may have been a population of organisms exchanging some genetic content (via strict sexual reproduction or not), but at the end, its first ancestor was the first self replicating structure of its lineage.
Note: I'm not saying it was the first replicator of the Earth, life may have appeared several times before, but only one lineage survived.
Anyway, the first replicator probably appeared among a population of similar non-replicating molecules, but its descendents may have recombined with similar replicators of independent origin, i.e. we don't come from a single living being.
But we'll probably never know.

 Whether 1% or 100%, what matters is millions of data points examined and p<0.001.  This is what Davey doesn't get.

What's also matters is the relative time of divergence between humans and chimps (homininae and gorillinae to be accurate) compared to chimps and gorillas.
And it's not based on homology, but on difference. The last common ancestor of chimps and gorillas is 40% older than the LCA of chimps and humans, not 0.5% (assuming a molecular clock).

MarkCC argues that CSI is an oxymoron.

MarkCC needs to be invited onto Panda's Thumb.

I don't agree with his argument that CSI is an oxymoron. Complexity refers to the parts of a system (lots of different parts) whereas specificity refers to its function.  So, a lot of info is required to describe the parts of a system and a few info to describe its function.
To me, the concept is more a tautology very similar to IC : if something looks like it couldn't have evolved (complex) and looks designed for something (specified function), it may have been designed.

He even doesn't know that, until radioactive dating, people were thinking in terms of hundreds of millions of years, and the idea of a billions-of-years-old earth was a surprise to most everyone, geologist and biologist alike.

Plus, how does a 4.5 billion year old earth really impact biology? Not much unless you're studying the very beginnings of life, and that only happens in the area before 550 million years ago.

Huh, no.
See the latest nature: scientists have discovered 3.5 billion year old stromatolites whose origin is probably biological.

But I agree that nothing in the current theory in evolution says that 3.5 Gy are required to produce the current life forms. And it certainly doesn't require the universe to be 13.7 Gy old.

About 14C...
I'm note an expert, but you can't use 14C to date fossils that are more than 50 ky old.
When the level of 14C in a sample becomes close to zero, it just can't be measured with accuracy. The smallest error in the measure, or contamination, can completely alter the results. If one measures 0.00000000001% of 14C were one were supposed to detect 0, the error is indeed infinite. This is just obvious, but AIG takes this as an argument that the Earth is 6000 years old. They're pathetic.
And 14C can only be dosed in organic mater. Dating 1.5 My old fossils with this method is nonsense, and refering to this is just stupid. We have other radionuclides for that (Uranium, Strontium...). And of course, the author from AIG don't mention it.
He alos forgot the fact that fossils older than 6000 years have been precisely dated with radiocarbon.

Hello Folks.
I'm watching a documentary on what I may call our cultural channel ("Arte" for those who know it). It is about the ethnic groups that were considered as inferior in our western civilisation.
In this film, they claim that this racism culminated in "On the Origin of Species...", where Darwin described these people as primitive and missing links (between ape and civilised men, I assume). They even used the term 'evolutionist'.
I haven't finished to read the Origin Of Species, but I don't think Darwin said anything of the sort.
Can you confirm this?
See, I'm not used to hearing such things on TV, but you might be (Foxnews et al.). I'm wondering about writing and email to that TV channel. Do you think I should?

EDIT: In fact this is ambiguous. I recall Darwin using the word "primitive" in his book. But I don't think it had the meaning it has today.

It's true that mutations may occur at different rates in different genes. It's also true that some genes are more conserved in a population than others, and that this will generally be true for beneficial genes.

I think you are actually referring to *fixed* mutations (sometimes referred as substitutions, although they can involve insertions/deletions).
Mutation rates in genes doesn't depend on there functions, it mostly depends on the DNA polymerase environment (repetitive motives in particular) when it replicates a chromosome. It can also depend on the activity of transposable elements...
Substitution rates may indeed depend on gene function. If most mutations are deleterious, they won't be fixed in a population. That's why the substitution rate of the rDNA is very low (it isn't translated, so there can't be synonymous mutations).
What do you mean by "beneficial genes"?

Consider the choices for the mass of the population... You can  spend your money on bread and circuses until the end comes and you die horribly, or we can offer you the option of spending the short remainder of your life with privation to make possible the escape of a select few, with at least less bread and fewer circuses to amuse you before you die horribly. Take your pick...

I don’t think the mass population will be given this choice. And even so, I’m convinced it’ll choose your second option.
Anyway, space colonization won’t begin abruptly. We spend billions of cash so a couple of people go to Mars. Aren’t there research projects exploring possibilities for the development of new propulsion techniques? Unless I’m mistaken, nothing profitable will be done on Mars that can’t be done here for less cost. This isn’t only fundamental research, but a first step towards space colonization. That’s what NASA’s engineers and directors basically say on TV. And I really don’t think their project is motivated by the economic profit that their grand-grand-grand children may get.
And the mass population would buy more bread and circuses with those billions spend in space exploration.

And here's something else to think about: my understanding is that bacteria in general have better error-correction machinery, and less non-coding DNA, than eukaryotes (bacteria are generally the pioneers when it comes to biochemistry). If true, this would go some way towards accounting for the fact that bacteria have in some sense evolved much more slowly than eukaryotes

Evolution refers to heritable changes.
We like using the term “evolved” for lineages that have undergone more phenotypic changes compared to other “primitive” lineages, since their divergence. Using this criterion, we would be a lot more “evolved” than bacteria, but not more adapted.
We have a definition of adaptation though it’s not quantitative in the absolute sense, and I’m not sure it can be used to compare very different organisms.

Well, it's not very well written and it contains mistakes (wrong interpretations of the fossil record, etc).
The increase of mutation rates under stress is a known phenomenon, that doesn't mean that mutations are not random, in case you think so. They say:  
Quote
Since the cause of cell function disruption is random, the resultant mutation's effects on the regulation of development and its ultimate phenotypic expression are also random. In short, if a newly emergent phenotypic property does not kill you, you have it.

They refer to macromutations, but don't discuss their effects on survival and fecundity (fitness), which is contradictory.
I don't think their is any evidence of stress induced macro-mutational changes, leading to new animal and plant species, except their misinterpretation of the fossil record (plant polyploidy is something else). They completely ignore the current theory of speciation, which is well supported.  
Quote
geographically isolated subspecies become true species by accumulating minor genetic changes that eventually lead to reproductive incompatibility. Nowhere, however, in these or subsequent formulations of evolutionary change resulting from accumulated genetic modification is the cellular “target” of inferred mutation identified.

this model does not require scenarios of reproductive and/or geographical isolation for the emergence of novelty.
This is just stupid. No one said that isolation was required for novelty, but without reproductive isolation, speciation is by definition impossible. Hence, their model don't achieve what it was meant to: explain the origin of (some) new species. It could merely account for phenotypic evolution within a lineage, but as long as you don't have a mechanism of reproductive isolation (which they don't provide), cladogenesis is impossible.
In fact, this is a reminiscence of the old school of speciation by mutations (Bateson, Goldshmidt) whose arguments were debunked by Dobzansky and Mayr 50 years ago. The fact the the authors ignore the recent literature on speciation (although they quote Mayr, 1942) makes me wonder how they got published.

Yes, heat shock proteins are involved in the expression of mutations, but I’m not sure whether their inactivation under stress has been proved to be adaptive (not sure of the syntax either). However, I don’t know much this topic, and recent info would be welcome.
We could see that phenomenon as a simple disorder in the metabolism of stressed organisms, where HSP can no longer do the job it was selected for. Using this line of reasoning, the production of monsters under high exposure of radiations could also be an adaptation.
If the production of mutant phenotypes under stress is adaptive, it was favoured at some point. This implies that variants bearing “defective” HSP under certain conditions were selected because it increased the probability of survival of their lineages. That’s quite possible, and it would be completely compatible with Darwin’s ideas.

Genetic evidence for complex speciation of humans and chimpanzees

Nick Patterson1, Daniel J. Richter1, Sante Gnerre1, Eric S. Lander1,2 and David Reich1,3

Abstract
The genetic divergence time between two species varies substantially across the genome, conveying important information about the timing and process of speciation. Here we develop a framework for studying this variation and apply it to about 20 million base pairs of aligned sequence from humans, chimpanzees, gorillas and more distantly related primates. Human–chimpanzee genetic divergence varies from less than 84% to more than 147% of the average, a range of more than 4 million years. Our analysis also shows that human–chimpanzee speciation occurred less than 6.3 million years ago and probably more recently, conflicting with some interpretations of ancient fossils. Most strikingly, chromosome X shows an extremely young genetic divergence time, close to the genome minimum along nearly its entire length. These unexpected features would be explained if the human and chimpanzee lineages initially diverged, then later exchanged genes before separating permanently.

As I said in another thread, in sexually reproducing populations, recombination breaks the interactions between genes, hence the phenotypes. A phenotype can't be selected if it can't last through generations.
On this basis Dawkins (and before him, Williams) defined his concept of gene : a replicative element that is not broken by recombination.

If a gene can increase its replication rate while decreasing the fecundity of its bearer, it will be selected anyway. Nothing can prevent it, that's the definition of selection.
The main examples of this are altruism, segregation distortion, male cytoplasmic sterility... which BTW completely disprove any Intelligent Design.

ahhh, but that doesn't mean there still couldn't be genes acting to increase their own reproductive rates, either in conflict or in concert.
Sure. In fact, the examples I gave often involve conflicts between genes (on different chromosomes or organelles)
Quote

besides which, one could easily argue that increasing the fecundity of the host would have a long term benefit to increasing the frequency of whatever gene contributed to it, yes?

The fitness of an individual can explain most of the observations but not all, and those exceptions matter a lot. Meanwhile, the concept of gene fitness has never been contradicted, AFAIK.
You could also say that increasing natality in a population benefits the alleles contributing to it. True, but can you explain the sex ratio of 1:1 in panmictic populations, while it should be biased towards more females for an optimal growth rate? You certainly has the answer.

playing devils advocate, extend the idea of sex ratio bias beyond what you just mentioned.

If you're a self-interested gene, why have sex at all?

wouldn't asexual cloning be faster and cheaper?

I realize this overlaps with the recombination issue, but since you brought up the idea of ESS and sex ratios, I thought it would be worth approaching from that angle as well.

Sexual reproduction is currently unexplained (or at least no one provided a consensual explanation).  It doesn't contradict the idea of selfish gene more than it opposes the concept of indivual or group selection, the latter being falsified by the sex ratio.

I want to stress that gene selection-or mutation selection to be more accurate-is the natural consequence of DNA replication, which is the basis of reproduction. I think it's the most fundamental conception of natural selection, hence the best we have, by the principle of Occam's razor. We don't need entities like individuals, populations, species, etc. It is also explains observations that the other theories couldn't.

A nucleotide can only be said to have a certain phenotypic effect within a given DNA sequence. Cytosine cannot be said to have a certain phenotypic effect on an organism compared to adenine except in a given sequential order of nucleotides.  However, it is meaningful to speak of the phenotypic effect of, say, a gene for green eyes as opposed to a gene for blue eyes, for a gene can be said to have a consistent phenotypic effect which is for the most part independent of its location in the genome, which is not true of a nucleotide

I don't completely agree. A single gene doesn't have more effect than a single nucleotide. If I follow your reasoning about the nucleotide (that I find correct), a gene alone is also meaningless, without the hole genome and the environment (which includes the cytoplasm and translation mechanism that is present in the zygote).
For point mutations that have a significant effect on fitness (typically, some cases of resistance to antibiotics or insectisides), the mutated nucleotide is the fundamental unit of selection : the gene where the mutation occured can be broken by recombination (even if a similar gene is reconstituted), but the mutated nucleotide can't. We can assimilate it as the replicator which increase its replication rate.

Oh, and since you like dumping AIG's garbage here, I feel free to post an appropriate quote from Why I believe the Earth is old  
Quote
"Flood geology" has been dead ever since leading Christians scholars in geology at Cambridge and Oxford rejected it, and that was before Darwn's Origins was ever published.
By the 1850s, Christian men of science agreed the earth was extremely old.
For some of their reasons, see, "Reasons Why 'Flood Geology' Was Abandoned in the Mid-1800s by Christian Men of Science".

Such men included:
Reverend William Buckland (head of geology at Oxford)
Reverend Adam Sedgwick (head of geology at Cambridge)
Reverend Edward Hitchcock (who taught natural theology and geology at Amherst College, Massachusetts)
John Pye Smith (head of Homerton Divinity College)
Hugh Miller (self taught geologist, and editor of the Free Church of Scotland's newspaper) and,
Sir John William Dawson (geologist and paleontologist, a Presbyterian brought up by conservative Christian parents, who also became the only person ever to serve as president of three of the most prestigious geological organizations of Britain and America).
All of these giants of the geological sciences rejected the "Genesis Flood" as an explanation of the geologic record -- except for possibly the topmost superficial sediments, though Adam Sedgewick and Buckland later abandoned even that hypothesis.
Neither were their conclusions based on a subconscious desire to support "evolution," since none of the above evangelical Christians were evolutionists, none became evolutionists, and the earliest works of each of them were composed before Darwin's Origin of Species was published.
The "Flood geology" of Henry Morris (founder of the Institute for Creation Research), was a revival in the 1960s that even failed to convince the American Scientific Affiliation -- a longstanding group of Evangelical Christians and scientists whom Morris fled to form his own little group of strictly young-earth creationists, the Institute for Creation Research. Henry Morris' book that sparked the "Flood geology" revival, The Genesis Flood, is filled with so many errors that it appears to be more a work of "Satan" than of God, since it lies about so many things, from the Paluxy manprints (that ICR and Answers in Genesis have since backed away from); to the "human skull found in coal" (the "Frieberg Skull" that two articles in the Creation Research Society Quarterly later debunked contradictions.darwin.ws/skull.html; to the "Lewis Mountain Overthrust," the world's largest overthrust and reversed layer formation in geology that Morris said would turn the world of modern geology upside down (but later, two ICR scientists, Steve Austin and Kurt Wise, admitted that the evidence that the "Lewis Mountain Overthrust" was a genuine overthrust was reliable, so they have ceased using the world's largest overthrust as evidence of a topsy turvy geological record). In fact, Answers in Genesis has backed away from nearly all claims that "pre-Flood" human bones or artifacts of "pre-Flood" civilizations have been found, and suggested that no such evidence may ever be found. Answers in Genesis has even produced an article at their website concerning "Arguments that Young-Earth that creationists should NOT use
Makes one realize how many Young-earth arguments over the years have added up to cases of embarrassment for creationists far greater than"Piltdown man" and "Nebraska man" were to evolutionists.

The evidence for an OLD earth presently includes:

1) Individually dated tree-rings in two or three separate tree-ring series, stretch back 12,000 years. (Even Young-earthers like Aardsma, formerly with the Institute for Creation Research, have admitted that the evidence from individually dated tree-rings in two totally separate tree-ring series on two different continents, demonstrates the reliability of C-14-dating stretching back 12,000 years in time).

2) Individually (C-14)dated varves in a lake in Japan, stretch back 40,000+ layers. (Green River varves have not been individually C-14 dated, but that would be an interesting experiment to perform since there are over 2 million layers per ancient fossil lake in that region, and all toll, when you count the layers of all the fossilized lakes in that region, noting the lowest and highest layers in each lake and how the time overlaps in each lake, there are over 6 million layers.)

3) Deep ice cores feature 100,000 layers of ice -- each layer having its own distinctive isotopic signature (and other types of layer-distinctive signatures as well), stretching back over 100,000+ layers.

4) Evidence of extremely slow sea-floor spreading over a 100,000,000 years. New sea floor is seen forming today from molten rock that emerges from a ridge that runs right down the middle of the Altantic ocean. On each side of that mid-Atlantic ridge, new molten rock continues to emerge, then it cools and hardens, and the date of cooling (as well as the direction and strength of the earth's magnetic field at the time it cooled) is sealed inside the rock in the iron crystals that harden there. Then the next strip of molten rock emerges from the mid-Atlantic ridge, cools, and hardens, as the continents on either side of the Atlantic ocean continue to drift slowly apart from each other. Thus are formed distinctive strips of sea-floor rock that run all the way from the middle of the Atlantic ocean (where the youngest radiometrically strips are) to the shoreline (where the oldest radiometrically dated strips are found). Such strips of rock along both sides of the mid-Atlantic ridge reflect over a hundred million years of sea floor spreading that occured as the continents of North and South American slowly drifted away from Europe and Africa.

Moreover, the radiometric dates that stretch from the middle of the Atlantic to the shoreline, agree with independent measurements (both land based and satellite based) of the present rate of movement of North and South America away from Europe and Africa. In both cases, the expected time it would take for the continents to move apart at their known present rates of speed are the same.

Even Young Earther's agree that if you try, as they have, to explain the evidence for extremely slow sea-floor spreading simply by speeding up the process and imagining that the continents zipped into their present positions in a mere "year," that hypothesis would require a MIRACLE to cool the molten rocks down instantly and in distinctive stages -- because if the continents "zipped" along, then the rocks and their radioactive isotopes would have run together like soft butter spread on microwaved bread, neither would the sea floor rocks exhibit the crystallization patterns that rocks exhibit that have cooled under conditions of much lower temperatures and pressures, which is what the sea floor rocks presently exhibit. Moreover, after the continents had ceased "zipping" along but slowed to their present extremely slow speeds, what odds would there be of achieving the same MATCH between the known range of radiometric dates of sea-floor rocks from the middle of the Atlantic to the shoreline, AND the present speed of the continent's moving apart from one another today? What a coincidence! The strictly scientific odds look far better that the "continental zip" hypothesis is wrong, and the continents took over a hundred million years to separate, and at the same rate they are presently separating.

The evidence of an old-earth is enormous and defies the "odds." There are thousands of individually dated tree rings -- tens of thousands of individually dated lake varves -- a hundred thousand distinctive layers of ice -- and, sea-floor rocks formed in succession and having hardened over successive periods stretching back over a hundred million years.

I await your refutations, Dave.  :)

   Researchers found that about a dozen genes that help give rise to a shark’s median fins — those that run along its back and belly — also determine where paired side fins will form on its body. These genes are known to play important roles in the development of paired limbs in humans and other land animals.

   The genes come from an ancient ancestor shared by sharks and humans.

If by "random" you understand that a mutation can occur without a specific cause, then you are profoundly mistaken, skeptic.
Mutation involves chemical reactions, hence suitable conditions. They are known to be triggered by environmental stress for decades.
What is random, is the effect of (most) mutations on their bearers.

However I would point out that, in some bacteria for instance, certain loci controling gene expression (promoters) are more predisposed to mutate, inducing phase transition for instance.
Also, some transposable elements carry particular genes (resistance genes for example), and the activation of such elements lead to mutations whose effects may not be completely random.

EVIDENCE SUPPORTING A FAST SPLIT BETWEEN CONTINENTS, BY AIR FORCE DAVE

As Dr Podovski clearly shows (http://www.answersingenesis/arefullofshit.php) :  
Quote
the usual argument touted by atheist evilutionists regarding the age of basalts from the atlantic ridge (0 Million years) to the shores (160 Myears) is in fact convincing evidence supporting an instantaneous split between continents, occurring 4500 years ago.

Indeed, according to the groundbreaking hydroplate theory, the spacetime continuum in the oceanic crust became distorted, as the Altantic widened, due to the formidable lithospheric forces taking place (another prediction from Einstein's relativity).
Thus, time goes faster as we walk towards the shores. This explains why radionuclids in basalts decayed millions of time faster near the shores, compared to the rift.
Therefore, basalts appear millions of years older than they really are as they are sampled closer to the shores, because they formed solidified in a parallel hyperspace in the oceanic crust, whose spacetime becomes more and more distorted as we approach the shores. Of course, basalts sampled in this area show a normal decay rate in the laboratory: as soon as they are extracted from this parallel hyperspace, the decay of their radionuclids becomes normal again.


Another victory for AFDave.

Abstract

The developmental and evolutionary mechanisms behind the emergence of human-specific brain features remain largely unknown. However, the recent ability to compare our genome to that of our closest relative, the chimpanzee, provides new avenues to link genetic and phenotypic changes in the evolution of the human brain. We devised a ranking of regions in the human genome that show significant evolutionary acceleration. Here we report that the most dramatic of these 'human accelerated regions', HAR1, is part of a novel RNA gene (HAR1F) that is expressed specifically in Cajal–Retzius neurons in the developing human neocortex from 7 to 19 gestational weeks, a crucial period for cortical neuron specification and migration. HAR1F is co-expressed with reelin, a product of Cajal–Retzius neurons that is of fundamental importance in specifying the six-layer structure of the human cortex. HAR1 and the other human accelerated regions provide new candidates in the search for uniquely human biology.


So Dave, if you read this, you should be reassured.

Hi, Thomas.

This is the paper, I didn't read your thread.  :(

Well, I'm interested in the genomic comparison.

In short, they searched for conserved regions between chimp and mouse-rat (at least 96% identity over 100bp), to get rid of the junk.
Then, on these 35000 conserved regions, they selected the orthologs that differ the most in humans compared to other amniotes. They performed a likelihood ratio test (don't ask me) to check the significance of the differences.
96% of these 49 "Human Accelerated Regions" are non-coding. A quarter of them are adjacent to neurodevelopmental genes (regulation regions, promoters and such things, I guess. I didn't read the whole article).

=> proves that sedimentation mostly occures in water

2) the fact that the non water-laid sediments can be explained as short duration volcanic/tectonic processes during and after the Flood
=> is not a fact.

3) the fact that most layers contain marine fossils
=> proves that their are a lot of water and organisms in the ocean (using conclusion from 1)

4) the fact that present day mountain tops contain marine fossils
=> indicates that those layers were under the sea once

5) the fact of folded (uncracked) strata
=> proves that stata can be folded and remain uncraked

6) the fact of incised meanders showing that sediments were soft when the meander was cut
=> is wrong

7) the fact of two modern examples of flood waters creating very similar features to what we find in the Grand Canyon and other canyons
=> is wrong. Please, show us a recent (hystorical) river that eroded hundred of meters of granite.

8) the fact of historical records which tell of a great flood and legends of such from around the world
=> is not a scientific fact

ahh, yes, basically that's it:

http://www.molecularevolution.org/resources/lrt.php

I'm a bit confused here though.  It seems they are focusing on genes that produce interactive RNA?  this is something new to me.  do you have any more background on these kinds of genes?

When you get around to reading it in depth, let me know if you think the specific methods warrant the conclusions in this case.

cheers

Thanks for the clarification.
My knowledge in molecular evolution will have to be improved seriously by the time I build and publish my phylogeography. Is there a book you would particularly recommend?

I don't know much about interactive RNAs in general. I know that some micro-RNAs can somehow interact with mRNAs before or during translation (or something).
Mirco-RNAs seem actively studied. Someone of my research team works on the micro-RNAs that are supposed to interact with mRNAs of genes controlling the induction of sexual forms in aphids.

Regarding the methods they used, I am afraid I won't have the time to dig into this paper, but I can send it to you, if you wish.

Dave, your logic is just pathetic.

"hypothesis A implies observation B" doesn't no equal to "observation B validates hypothesis A".
Since you probably don't get this, here is a example :
"Geocentrism implies that the sun crosses the sky every day.
Thus, the sun crossing the sky every day validates geocentrism."
Got it?

Introduction to the scientific method, to which AFDave isn't familiar:
Hypothesis H1 true -> observations or results A
H0 true (=H1 false) -> observations or results B

Global Flud => some water-laid sediments <---- correct statement
no Flud => no water-laid sediment <---- WRONG statement!
Therefore, the existence of water laid sediments does NOT prove a global flood.

But I have another test,

A global Flud => kms of sediments laid in a few weeks => benthic organisms quickly buried => fossils of floating plantonic organisms in the upper strata, fossils of benthic organisms in the lower strata, everywhere.
Prediction observed? => no => no global Flud. Simple as that.

Can your little brain assimilate this? Probably not.  ???

"Whilst continents were moving at 100 miles per hour..."
"mammals were better swimmers than dinosaurs, and go burried after. Ichtyosaurs actually had difficulties because of their thick bones that made them sink, in this low-density fresh water. The stupid pterosaurs were caught by the Flood while fishing, but the more intelligent birds managed to survive a little longer..."
and "just after the Arch landed and the water evaporated [...] limestones were solidifying, dinosaurs were fossilising, and thousand of african swallows sent by noah, carrying sequoia seeds to repopulate the californian forrest that has been devastated".

1.  Just because the gene "jumped" to another chromosome, why can that not still be random?  To prove it is not random wouldn’t you have to document that other genes jumped and that all the genes jumping resulted in positive, not negative, results?
You still wouldn't know whether that one gene jumped in a natural process or not. However, transposable elements and other chromosomal re-arrangements are known for decades and are guided by natural processes, as far as we know. It's up to the DI to prove that the designer guides transpositions. They can even start their project rigth know. :p

2.  If the jumping genes produced a variety of fly that can, when mating, produce sterile offspring, I wouldn't think the ID folks would consider that an evidence of "Intelligence"--would I intelligently create a flaw in my design?
Well, IDers are very good at misinterpreting scientific results.
Quote

3.  Could not these changes have resulted from selection pressure and random mutation?
Yes they could and they do. But the fixation of the transposition, which appears deleterious (produces sterile males), is the results probably from genetic drift, unless it was adaptive in a way we don't know.

4.  Does the mechanism of speciation have any bearing on the ID v. RMNS debate?  How does this "back door" to speciation change anything for ID?

See my answer to your second point. This find is another evidence for macro-evolution by mutations, dift and/or NS. Actually, I would have expected IDers to dismiss this discovery.

I suppose you mean macro-evo?  I think you are confused.  Noah did not have to carry millions of animals on the ark because micro-evolution does indeed occur and many varieties of animals would have developed after the Flood from just a single pair.  The reason he had to carry 35,000 (Morris/Whitcomb's guess) is because macro-evo has never happened and never will happen.

Variety (biology)
From Wikipedia, the free encyclopedia
In botanical nomenclature, variety is a rank below that of species: As such, it gets a ternary name (a name in three parts).
A variety will have an appearance distinct from other varieties, but will hybridize freely with those other varieties (if brought into contact). Usually varieties will be geographically separate from each other.

But please, gohead and explain us how the million of *known* species of insects are only varieties of a few species.
Are gorillas and macaques two varieties of the "primate kind"?
In this case, you would'nt mind considering human and chimpanzee as two varieties of the "ape kind" Davey, would you? :)

And of course, sometimes after the flood(?), mutations rates were thousands of times higher than they are today. Is it linked to the faster rate of decay, Dave? My theorie of a space-time distortion, could be handy.
 
Quote
If macro-evo was possible, there would be no need for an ark to preserve distinct kinds.

Interesting reasoning. "The Arch had to preserve 35 000 species since macroevolution doesn't happen. 'Cause if it did, Noah wouldn't have had to preserve those 35 000 kinds. Duh." :D

You assume your flood carved the Grand Canyon, despite the fact that you have no evidence your flood ever even happened, and even if you did, you have no way of knowing if the Grand Canyon happened before the flood, during, or after the flood, because you have no independent method of dating it. Was every canyon everywhere carved during the "flood"?

Sorry if this sounds obtuse but how could a Global flood create a canyon? Any canyon. If the whole World was under water, how would it move in a way to carve rock like that?

Open to anyone.

I've wondered that for years.

I think it reflects a Creationist thought process "Lots of Water Do Big Thing,  Make Canyons". I don't think they think it through further than that.

Our friend Dave referred to underground sources of water, therefore unable to erode lanscapes. But presumably, there was enough rain for the erosion of the Grand Canyon in 40 days, but not too much so that Noah could build his arch safely.

Im pretty sure cyctochrome C doesn't determine what an organism looks like. An yes to your question by the way.
So you actually believe that a 400 MYO lungfish had significantly different sequences that the modern lungfish which is still living today?  How much different?  Can you hazard a guess?  20%?  40%?

It's not a guess, dude.

With cladistics (not based on genetic distance, BTW), we can infer the molecular states of extinct ancestors. The genetic distance between this ancestral "lungfish" and its descendent can be calculated. And it goes further, we could predict which point mutations occured in its lineages.

Biologist : "No, those proteins are essential to life and cannot be altered hugely -- they must remain basically the same to function, which is why human cytochrome c can be used by yeast."

This is not the best explanation. Sequence divergence is mostly correlated with time of divergence, not morphology.
The divergence in protein sequence can be rather large and the data remain the same for neutral mutations.

Based on your statement about the clade enclosing archae and eukaryotes, I'm guessing the first. Am I right?

Regarding the root of the tree... I am not sure what you mean. The infered common ancestors of each of the three empires are very distant from each other, which implies that a lot of intermediate forms disappeared. But this doesn't alter the fact that LUCA was, at most, a population of indivuduals if gene flow was possible between lineages (some sort of sexual reproduction). Anyway, all lineages eventually coalesce to a single one, a single cell, be it LUCA or one of its ancestors.

The first tree represents the correct phylogeny even if the consensus is not shared by the whole scientific community. I think that the term "bacteria" should be used instead of "prokaryotes" to avoid a confusion.

Dude, it doesn't prove your point, it proves that organisms which diverged recently are less distant. You took two fish that belong to the same recent family, you idiot. Do you know how many families of fish there are?
Aves and especially homonidae appeared rather recently.

I challenge you to compare the genetic distances between shark and salmon or sponge vs. jellyfish to the distances that separate them from humans. It will prove that you are wrong.

Quote (Henry J @ Oct. 07 2006,16:13)
Something I'm wondering about - average mutation rates are typically given as per number of generations. But with multicelled critters, doesn't the DNA typically get copied several times between one generation and the next, as the organism matures enough to produce offspring? Could that be a factor in why the short generation and long generation species seem to match up on the amount of accumulative mutation?

This amount depends on the fixation rate of new alleles, which essentialy varies with generation time, effective population size and of course mutation rate per generation (for neutral mutations). The latter variable is too low to allow the accumulation of mutations at the same locus in a cell line, even if gametes are produced after many cellular cycles.
However, species whose germinal cell lines undergo many mitosis should have higher mutation rates per generation, all else being equal (which is unrealistic). However, I don't think a longer generation time can be compensated by a higher mutation rate per generation. The differences are not in the same order of magnitude. Moreover, I am not aware of a higher mutation rate/generation in organisms with longer lifespans.

And I'd like to stress again that this reasoning only applies for neutral mutations. We don't know the selection coefficients of the mutations involved in the CytC distance matrix that our friend provided.

In the late 1970's, Stephen J. Gould challenged the synthesis model of evolution, and proposed a punctuated equilibrium model...

The challenges to the modern synthesis have been overstated, and  by Gould himself (see Ridley for a discussion on this topic).
Nowhere in the equations it appears that morphological changes (that define species in paleontology) must evolve at a constant rate. On the contrary, it is well know that strong selection and founder effect (drift) can accelerate the fixation of new alleles.
And Gould's model is based on Mayr's ideas, specifically peripatric speciation.

Whether it's your tree or not doesn't change much.
The left tree doesn't has all species on earth indeed, not only it would be tough, it would be pointless. We don't need to put 10 species of animals in the tree of life, we already know they belong to same group: the tiny branch you see on the right, next to the fungi.
The tree on the right doesn't even show plants nor fungi.

I've never cared for this argument because it implicitly confuses what must be true with what we observe.

Nothing is "true" beyond what we observe. Trueness is a human concept. I fail to see your point.
   
Quote
The brittleness of the parameters is an empirical observation; we could very well have existed in a "life friendly" universe that accepted broad changes to the constants.

How does this refute my argument? You are just saying that "if the universe were totally different, then I could argue this [which is not a counter-argument anyway]."

Not even considering that those constants are not part of a universal "reality". These are human constructs too. Most astrophysicians argue that reality is not reachable, and I concur. It's just impossible. For instance, atoms are not "real", they are a model that seem to explain well our observations.
I also miss the whole point of arguing "if the universe were different, then...". We could still claim that the universe is fine-tuned for it allows the constants to change broadly (if that were the case). And why do you want to change the constants anyway? Why don't you want to modify the climate in East Africa some millions years ago to prevent the evolution of homininae?
Eventually, it all boils down to "if the universe had not allowed human life to emerge, then this would be a world of sh*t, therefore it's fine-tuned".
To me, saying that the universe is fine-tuned explains nothing. It's just Goddidit. Is God fine-tuned too?

At last, one could have a serious discussion with you, after a whole year.  :)

Well, it's true I'm implicitly taking fine tuning as the null hypothesis, but only because the observations pushed it into the "null" position. If the calculations and observations had shown that our universe wasn't sensitive to small changes, then the atheistic position would have gotten the presumption. And even so, there are competing ideas that can still topple the Design Hypothesis; for example, if evidence in favour of the multiverse turns up, then the Design Hypothesis is ruled unlikely due to Occam's Razor. But I won't favour methodological naturalism a priori under all conditions.

This hypothesis is still not falsifiable.
I don't see what the multiverse could change. Even if most of the "universes" were hostile to life, in what way would this be different from the fact that our universe is mostly hostile to life? You could still argue for fine tunning.

This hypothesis is still not falsifiable.


But it's not trivial, because the observations could have gone the other way. Say I pick a ticket with the numbers 12345. Should I be surprised? This depends on:

1) How freely the numbers can vary;

2) How many other people are playing.

As 2) increases, then the individual odds don't change, but the chance of that ticket being selected approach unity. I would be very surprised if the total possibilities were high, and the number of participants was low.

A few points:
- You have not defined your hypothesis. What is a "fine tuned" universe ? A universe where human consciousness can arise? Where life can appear? (in these cases the answer is trivial). A universe designed by God?
- We don't know wether the constants describe the universe with precision (= wether they mean anything beyond our interpretation of reality).
- We don't know the distribution function of these constants, if that even makes sense.
- Even if we knew it, a high probability for their current values would not falsify your hypothesis (universe created by God).
- Their values don't add any support to your hypothesis, no more than the probability of the sequence of mutations that led to human consciouness. Why don't you support prescribed evolution, while you're at it?

It's entirely possible that the allele for blue eye color didn't even exist until a few thousand years ago (even if, unlike Dave, you believe humans have existed for 200,000 years).

Interestingly, I read that some human alleles coding for proteins of the HLA system diverged even before humans and chimps did.
Usually, different alleles can't been maintained that long in a population , one eventually reaches fixation (in 4Ne generations for neutral alleles). In this case, they were maintained in our lineage for millions of years by superdominance (the advantage of heterozygotes).

I don't know if it's consistent with Dave's hypothesis, though.

I understand, conceptually, random mutation and natural selection and I find it perfectly logical.  I can even understand it as a means of speciation over long periods of time.  But I tend to think of ancestry as individuals growing into populations and this seems to imply something different.  What is tripping me up is the comment that the ark story couldn't possibly be true because it would limit us to 16 alleles.  Let me try it this way.  Today there are 6B or so homo sapiens.  At some point, in the distant past, there were none.  If I was to roll the clock backwards, shouldn't I find a point where there were only a handful of homo sapiens and wouldn't the number of alleles be necessarily limited by that population?  The comment earlier that the ark story can't be true because it would only account for 16 alleles while we know there are far more.

I realize that this is probably way too basic of a question to distract you from the main event here.  So, don't feel obligated to walk me through it, if there is a basic genetic primer somewhere around.  I'm perfectly willing to do my own work.

EDIT:  Okay.  Eric's explanation makes sense.  So, the ark being a bottleneck doesn't refer to the limited number of alleles but rather the time needed to mutate into the diversity of alleles we see today from a "starting point" of 16?

It's better to consider alleles, not individuals. All the alleles for a gene eventualy trace back to a common ancestor, which is the coalescent. This common ancestor (gene) can precede the first members of a given species, or the opposite. See my precedent post for an example.

Anyway, it could be possible to have our current polymorphism from only 8 individuals at the beginning (assuming imbreeding is not a problem), but it would take a lot more than 4500 years (even for purely demographic reasons).

More from Ayala on the incredible variation potential available with no mutations at all ...  
Quote
Ayala, Francisco J., “The Mechanisms of Evolution,” Scientific American, vol. 239 (September 1978), pp. 56-69.

p. 63
“It therefore seems clear that, contrary to Darwin’s conception, most of the genetic variation in populations arises not from new mutations at each generation but from the reshuffling of previously accumulated mutations by recombination. Although mutation is the ultimate source of all genetic variation, it is a relatively rare event, providing a mere trickle of new alleles into the much larger reservoir of stored genetic variation. Indeed recombination alone is sufficient to enable a population to expose its hidden variation for many generations without the need for new genetic input by mutation.”
p. 64
“In any case there can be no doubt that the staggering amount of genetic variation in natural populations provides ample opportunities for evolution to occur. Hence it is not surprising that whenever a new environmental challenge materializes—a change of climate, the introduction of a new predator or competitor, man-made pollution—populations are usually able to adapt to it.


Now with this in mind what about your supposed "bottleneck"?

Dave, you don't understand this quotation.
Ayala is discussing whole populations with "stored genetic variations" that result from (guess what?) mutations, and he makes it perfectly clear.

In a population of two individuals, you can "store" 4 alleles per locus, at most.

Interestingly: only two of Adam and Eve's children had any descendants. I never read the Bible (gasp!;) but our fundy can confirm this.

Quote (afdave @ Oct. 19 2006,10:22)
I just answered my own question about "Why could Adam not have had multiple alleles for a given gene?"

 
Quote
Basic features of heredity > Mendelian genetics > Allelic interactions > Multiple alleles

The traits discussed so far all have been governed by the interaction of two possible alleles. [I assume this is quite common?] Many genes, however, are represented by multiple allelic forms within a population. (One individual, of course, can possess only two of these multiple alleles.) Human blood groups—in this case, the well-known ABO system—again provide an example. The gene that governs ABO blood types has three alleles [OK, not much more than two]: IA, IB, and IO. IA and IB are codominant, but IO is recessive. Because of the multiple alleles and their various dominance relationships, there are four phenotypic ABO blood types: type A (genotypes IAIA and IAIO), type B (genotypes IBIB and IBIO), type AB (genotype IAIB), and type O (genotype IOIO).

[url]heredity. (2006). In Encyclopædia Britannica. Retrieved October 19, 2006, from Encyclopædia Britannica Online: http://www.britannica.com/eb/article-50777 [/url]


So now a logical question would be ... "What percentage of genes have only two alleles and what % have more than two?"  "What causes a gene to have more than two alleles?"  ... and other such questions.

The proportion doesn't matter.
Microsatellite loci have are highly polymorphic (several dozens of alleles) and are found everywhere in our genome. If all the alleles were present in Adam and Eve from the start, that means both (and their descendants) had hundreds of chromosomes.
The fact that some genes only have one allele won't change that.

Ghost of Paley,

It seems that you don't directly equate fine-tuning to God. Which leads me to a few questions I wan't you to address here. Please don't just provide links, I find that kind of answer annoying. I won't bother to read them.

What precisely differentiates a fine-tuned and a badly-tuned universe? It appears that, for you, a fined-tuned universe is suitable for life, although I don't see how you get the "tuning" from this observation alone. In that case, could a universe that is not propitious for (to?) human life be also fine-tuned? Justify your position.

What arguments lead you to conclude that a fine-tuned universe is the creation or God? I suspect this has to do with some low probability.
Would a high probability falsify the action of God? In other words, how could one falsify your hypothesis?

Do we have any theory that is relevant outside our universe, that says anything about the conditions for its appearance? (In other words, is infinity reachable?)

In that case, why would these particular conditions be more relevant to demonstrate the action of God, that, say, the conditions for the appearence of our hypothetical mutliverse, or the conditions for the apearence of life on Earth, Homo sapiens, yourself? In other terms, what did God design? Did he design himself? Justify you position.

No, my friends, mutations are a BAD thing, or at best a NEUTRAL thing.

Dude, you don't know what you're talking about. You sound like John Davison. Have you heard of this old clown?

So according to you, the average thousand of species that descended from a couple of individuals in the Arch are "BAD things"?
The different species of salmonids adapted to salty and fresh water are all "BAD"?

How did penguins reach Antarctica after the flood, genius? The ice must have melted underwater, I guess. Or did they adapt to some cold environment afterward? But wait, adaptation is impossible as you just said.

Get a clue, Davey.

Apparently, Dave believes that a couple of individuals can give birth to a thousand of species without the need of mutations, just because it can produce billions of different offspring.

(Ok, maybe you should read a biology book first, but let's try it anyway ???)
So, Davey, if speciation (post-flood evolution) were just based on recombination (allele shuffling) and mutation never produced any adaptation, why have we never seen a couple of individuals giving birth to another species in one generation? (let's not consider hybrid speciation) This should be common according to your bogus theory. Don't deny it, I know you never predicted this YECs don't know what a prediction is.

Or maybe you still think that some organisms can be 500-ploid?   :D

What's surprising is the narrow room for error. If you could change the fine structure constant by several orders of magnitude and still obtain carbon-based life forms (the only form of life of which we know), then I wouldn't consider it very surprising. Or, if we had evidence that many other types of life were possible, I wouldn't be suspicious. But the parameters are pretty narrow; any change of more than 4% renders the development of carbon-based life impossible.

You're not answering any of my questions.

I was asking you, what do you consider "fine-tuned"? Apparently, it means suitable to carbon-based life. Why carbon-based? Must it include human life, life on Earth? Justify your position.

I was under the impresion that the fine tuning argument was not that there are narrow parameters for life; But the parameters for the Universe existing are narrow.

This applies to all the 4 forces.

The easiest to remember (for me) is gravity. Slightly stronger=Universe collapsing before the first star forms. Slightly weaker=no atoms forming.

The observation of "fine-tuning" is not just a creatioist view. Both Stephen Hawking (a signatory on project Steve) and Brian Greene mention it in detail in their popular science books.

I've read Hawking's book and I don't remember any mention of "fine-tuning". It wasn't in English though.

No atomes != no universe.
So I'm asking again. Under what conditions would Paley consider a fine-tuned universe : atomes, carbon-based life, Homo?

Not to mention that speculating on the probabilies for the appearence of the universe is nonsensical. The probabilities are part of the universe too, according to the definition: the universe (metaphysical) = all.

Not if there is more than one universe. Then probabilities can be applied. With one universe, then the discussion becomes entirely metaphysical.

"More than one universe" just moves the (non) problem further. It's nothing more than terms.

HOW MANY MUTATIONS REQUIRED TO GENERATE THE PRESENT CONDITION?
In most cases none.  Why?  Because pre-Flood animals could have easily carried 4 alleles per locus.  Woodmorappe notes that most loci have [today] fewer than four alleles per locus.  And of course this is easily explainable due to the strong probability that the Ark animals did not always carry the maximum possible four per pair.  (Woodmorappe, p. 195)

But according to your hypothesis, Davey, one pair of indivuduals gave birth to a thousand of species (except humans, for some reason). And a thousand of species represents thousands of alleles per locus.

The problem is eliminated in a suitably large multiverse, because this would indicate that the universe had enough trials to hit upon the "correct" constants. But if we find evidence for only a handful of universes, each possessing dramatically different constants and all but one -- ours-- barren of life, then the probability of our universe goes down IMHO. For a suitably evidenced TOE, it's hard to say which hypothesis should be favored, although most scientists would find naturalism vindicated.

Would this falsify fine-tuning? I don't think so.
A large multiverse? What does that mean? Isn't the mutliverse supposed to be infinite?
Before we go any further into this pure speculation, I would like you to define the mutliverse. First, what differentiates two separate universes?

And you've yet to define what you consider a fine-tuned universe.

Read it again. The terms are different but the arguments are the same.

According to both Hawing and Greene we are in a weird situation. They both want the laws to be "plausible" and both see a difficulty.

This is not just a creationist view. Aparently most cosmologists/astrophysicists see a problem.

The vast majority are looking for naturalistic causes. This is the only reason that string theory is taken seriously BTW.

Hawking is not being scientific if he uses this argument (God), I'm sorry.

I know some other cosmologists who claim that no astrophysicist/cosmologist nor anyone else is entitled to draw such conclustion. They just don't know. Resorting to a omnipotent supernatural being because we can't explain the world we live in isn't science. It's creationism, plain and simple, be it from a YEC or a Nobel prize in physics.

I really don't see where the "problem" is. Since I don't have the book right now, you'll have to explain me. The universe is all, speculating about its nature in terms of probabilities is nonsensical, as I have shown. Probabilities are part of the universe itself, by definition. This isn't astrophysics, it's logic.

No one here has offered any definition of a fine-tuned universe, let alone a way to fasifiable the fine-tuning hypothesis

I read the abstract of Nijhout's paper. He describes alleles of large effects. What's the problem?

I don't see why the first steps of mimicry would require mutations of large effects in all species.
The initial ressemblance could be the result of another selective factor, an exaptation. For instance, two species of toxic insects could develop flashing colors that warn predators. If the flashing colors are closed (it's quite plausible), predation by birds will favor the ressemblance between the species (mullerian mimics). Then one species may lose its ability to produce toxin, but will still benefit from the toxin produced by the other (batesian mimics).
And this is just the first possibility I have in the top of my head (hope this is the correct expression...).

Regarding the mimic and the model living in different regions... Well, migrations/local extinctions could easily explain this. Maybe the aeras of both species were overlapping, in the past.

What's particularly interresting in this discovery is that it gives us a glimpse of the loss of fins in the past.
If the pelvic fins had been lost gradually until their complete disparition, through hundreds of mutations and alleles (at different loci or not), should we expect them to re-appear this way, in a single individual? It seems probable that the mutation which occurred in that individual is the reverse of the mutation that happened in its lineage.
Even a recombination of two or more "ancestral" alleles could not easily explain that. Those alleles must have been lost a long time ago.
This dolphin show us what the pelvic fins looked like just before they were completely lost. Of course, it was in a different species and the fins were not exactly the same.

What's a fine tuned universe (third time asking)?


Here's my definition. Notice that there are three components:

1) The constants for life have a low tolerance, which means that a small change makes carbon-based life impossible. This part is not controversial, and should be included in any model that seeks to explain origins.

2) The universe will probably not "choose" life-friendly constants because these constants are only a small subset of all the possible choices available. Therefore, our universe has a very small chance of existing. Everybody's still debating this part, of course.

3) This increases the likelihood that Something designed our universe. Most scientists reject this conclusion.

We don't know if our universe had a very small chance of existing, and this question doesn't make any sense if we consider that the universe is all (the definition I use).

You didn't give me a definition of a fine-tuned universe, but for what you said, I conclude it's a life-friendly universe.

3) follows from the definition (2) only if we consider life as a necessity or a goal. Necessity implies consciousness (unconscious things don't want anything), i.e. God.
So, you presuppose the existence of God in order to estimate a likelihood of design (i.e. the existence fo God). This is a tautology.

You're not refuting my objection with your quotes, Paley.

"Fine tuning => design" relies on a tautology.
Basically it says: for the universe to be life-friendly, the probabilities may be weak (which we don't know actually), so it must have been designed.

Translation: when God wanted to create life, he didn't rely on random chance because it would have produced an undesired result, hence the universe is designed, hence God exists.
You don't realise it (yet), but this is the underlying reasonning you have when you take "life-friendly" as an evidence of design.

Prove me wrong and show me your argument don't rely on a "required" universe, or show me that unconscious processes (non-God) can want anything.

Let's apply Spetner's methodology. The chance of the each addition letter being fixed is 1/26. And for each letter, we multiply by 1/26. So, that's 1/(26^10) ~ one in a hundred trillion total mutations. If our computer tried a million mutations per second, it would take a few thousand millennia to evolve — according to Spetner.

That's why Darwin proposed the hypothesis of gradual evolution (i.e. not saltation) by natural selection.

That was more than 150 years ago, but some people (namely Dembski) haven't understood it yet.  ???

So... radiocarbon dating is flawed because:
- total biomass was hundreds of times higher before the flood. (evidence?)
- That makes dead organisms appear older than they really are. (how?)
- Dendrochronology is flawed too. (proof?)
- thus calibration curves are not valid (so where do the correlation come from?)

Very convincing, Davey. Keep it up!  :)

1)  For your Carbon 14 dating system to work, you need to assume uniform C throughout earth history
Huh, no. Calibration curves show that what you call "C" (which is the atmospheric C12/C14 ratio) wasn't exactly uniform. There is a standard correction for that deviation. With our without, the Earth appears far more than 6000 years old. (and we're not even considering other radionuclids like U or Sr)

So this 100X more carbon was tied up in a huge mass of living plants, right?  When living plants grow from seeds, where do they get their carbon from Dave? From CO2 in the atmosphere.  So now you’re telling us that the atmosphere back then had 100X more CO2 than it does now.
       
Quote
This would make the C14 concentration 1/100 of what it is today all other things being equal.

Why would an extra carbon reservoir of pure C12 in plants affect the atmospheric ratio of C14/C12 Dave?  That’s all that matters for radiocarbon dating.

To be fair, I don't think 100x more biomass would require 100x the pressure of atmospheric CO2.

Not to support Dave, but the atmospheric C14/C12 ratio matters only indirectly in radiocarbon dating. The assumption is on the organic ratio, which is the same as the atmospheric ratio. If a plant only contains some C12, it would appear older if we have an overestimation of its C12/C14 ratio when it died.
But Dave never cared to explain why plants of a larger biosphere would accumulate more C12, compared to our plants. Hence, he proved nothing. Zero. How do you call this sort of blithering? Hand waving?

I doubt it.

Mutation rates and sexual reproduction are/were their fields of research. (Well, Kondrashov is interested in theoretical evolutionnary biology in general.)

The most famous paper produced by Kondrashov (it was in Nature) is a landmark in evolutionary biology. It explains the existence of sexual reproduction as a mean to purge deleterious mutations. It relies on high mutation rates.
Muller had a similar hypothesis (Muller's ratchet) but it involve longer timescales.

Now, it seems quite normal that these scientists want to prove their point by measuring high mutations rate. Does it prove they are creationists? Only a clown like yourself would think so.

Thus, if the genome size, G, in nucleotides substantially exceeds the N-e of the whole species, there is a dangerous range of selection coefficients, 1/G < s < 1/4N(e)

Our genome is 3.10^9 bp. Considering that most of it isn't translated, the size of our genome which may be subject to selection is probably shorter than a billion bp. What is our population size, Davey?

"The processes that can counterbalance that and explain how lineages has survived for 3 billion years are BS"

"Therefore life must have been created 6000 years ago; otherwise we’d be all dead"
(Condensed version:  “the Bible is right because it is”)

«Bible says that Noah lived hundreds of years"
"Thus, life expectancy has decreased ever since, because of deleterious mutations"
"Hence, processes that can counterbalance that are BS"

And regarding gene duplications, as I work on aphids, I'd like to post the abstract (and other parts) of an interesting paper about the function and evolution of a duplicated gene in a social aphid species.

Venomous protease of aphid soldier for colony defense
Mayako Kutsukake *, Harunobu Shibao *, , Naruo Nikoh , Mizue Morioka , Tomohiro Tamura ¶, Tamotsu Hoshino ¶, Satoru Ohgiya ¶, and Takema Fukatsu *, ||
PNAS | August 3, 2004 | vol. 101 | no. 31 | 11338-11343

In social aphids, morphological, behavioral, and physiological differences between soldiers and normal insects are attributed to differences in gene expression between them, because they are clonal offspring parthenogenetically produced by the same mothers. By using cDNA subtraction, we identified a soldier-specific cysteine protease of the family cathepsin B in a social aphid, Tuberaphis styraci, with a second-instar soldier caste. The cathepsin B gene was specifically expressed in soldiers and first-instar nymphs destined to be soldiers. The cathepsin B protein was preferentially produced in soldiers and showed a protease activity typical of cathepsin B. The cathepsin B mRNA and protein were localized in the midgut of soldiers. For colony defense, soldiers attack enemies with their stylet, which causes paralysis and death of the victims. Notably, after soldiers attacked moth larvae, the cathepsin B protein was detected from the paralyzed larvae. Injection of purified recombinant cathepsin B protein certainly killed the recipient moth larvae. From these results, we concluded that the cathepsin B protein is a major component of the aphid venom produced by soldiers of T. styraci. Soldier-specific expression of the cathepsin B gene was found in other social aphids of the genus Tuberaphis. The soldier-specific cathepsin B gene showed an accelerated molecular evolution probably caused by the action of positive selection, which had been also known from venomous proteins of other animals.

     
Quote
Soldier-Specific and Nonspecific Cathepsin B Genes Expressed in T. styraci. Many proteases including cathepsin B are known to comprise multiple gene families generated through gene duplications (41). It is thought that gene duplications have enabled the exploitation and evolution of novel gene functions, because new gene copy is freed from functional constraints of the original gene copy (42). Therefore, we examined whether cathepsin B genes other than the soldier-specific type exist in T. styraci. By RT-PCR using degenerate primers for cathepsin B proteases, expression of a different cathepsin B gene was identified in T. styraci. The full-length cDNA sequence of the nonspecific cathepsin B gene was determined. The 1,113-bp sequence contained a putative ORF encoding a polypeptide of 340 aa residues, exhibited 58.8%/51.3% (nucleotide/amino acid) sequence similarity to soldier-specific cathepsin B, and was constitutively expressed in both soldiers and nonsoldiers. From closely related social aphids T. coreana, T. taiwana, and T. takenouchii, which also produce second-instar soldiers, the two types of cathepsin B genes were identified by RT-PCR. Molecular phylogenetic analysis revealed that these genes formed two distinct and well defined clades (Fig. 6A). Semiquantitative RT-PCR analysis confirmed that, irrespective of the aphid species, the genes in the soldier-specific clade were expressed in a soldier-specific manner, whereas the genes in the nonspecific clade were expressed constitutively (Fig. 6B). These results suggested an evolutionary scenario that several copies of cathepsin B genes were present in an ancestor of these social aphids, and one of them acquired a novel venom function in the soldier caste.

Accelerated Molecular Evolution in Soldier-Specific Cathepsin B. In venomous animals such as snakes and gastropods, it was found that molecular evolution of their toxic proteins is strikingly accelerated because of positive selection acting on the molecules (43, 44). When exon and intron sequences of the soldier-specific and nonspecific cathepsin B genes were compared between T. styraci and T. coreana, such evolutionary patterns were detected; the KA/KS value obtained from the soldier-specific genes was >1, whereas the value from the nonspecific genes was «1 (Table 1). The accelerated evolution of soldier-specific cathepsin B is probably relevant to its venom function.

Eric-- Kimura's curve doesn't touch the vertical axis ... gets real close ... but doesn't touch it.  
davy, the graph is Kimura's model. If it doesn't actually touch the axis, that's because his equation for frequency asymptotically approaches infinity at the zero ("exactly neutral") point.

A frequency can't be greater than 1, which is a finite number.
But if it were an asymptote and if the model perfectly matched reality (what Dave thinks), it would mean that absolutely neutral mutations have an infinite relative frequency, i.e. all mutations are exactly neutral. But Dave argues the contrary. He can't understand/read his own graph correctly.
He is a infinite idiot, certified.  :D

Surely you are not telling me that good mutations can be selected for while the bad ones are discarded?  

In asexual organims like bacteria, selection operates at the individual (or genome) level. Even if several mutations occurred in the same bacterium before its division, what only matters in terms of selection is the overall fitness (reproduction rate) of the organism.
In other terms, we don't give a #### whether 0, 10 or 100 bad mutations use genetic "hitch-hiking" and are selected with one linked beneficial mutations. Mutants that reproduce faster invade the population. End of story.

In sexual populations, it's different. Since genomes can recombine, selection operates at the mutation (nucleotide) level. So beneficial mutation can be selected for while bad mutations that occured in the same genome can be selected against.

Dave, if VSDM have no effect on fitness or reproductive ability, i.e., they confer no competitive disadvantage at all, then by definition they are not VSDMs! They are neutral mutations, by definition.

Any mutation that cannot be selected for or against is by definition a neutral mutation.

For AFDave, a mutation is by definition deleterious.

Another way of looking at your "mutation load" problem is simply to say this:
You have not shown that deep time as revealed by radiometric dating methods (among many other things) is invalid. Therefore, I am entitled to point out that numerous species other than man have differential mutation rates and have survived over millions of years.

In the case of "mutation loads", on don't see why the relevant unit should be the species. Is speciation supposed to "reset" the alleged mutation load? All extant lineages have the exact same age, more than 3 billion years.

And I like to remind Dave that the evidence for a very old universe and biosphere is beyound doubt. Conversely, the hypothesis that mutation rates should have killed us hundreds of times is not verified at all. In fact, it's proven wrong by our existence.

Taking conjectures as facts and discarding possible explanations only prove you are intellectually dishonnest.

But the issue is: If he accepts that, does he not understand the huge, insurmountable problem this poses for HIS "theory", above all others?
And we're talking about initial populations of 2... Talk about small!

Dave appears to believe that, somehow, you can produce different species without mutations.

He mentionned something about phenotypic plasticity, which is ridiculous.
He mentioned the fact that a couple of individuals can produce billions of different children, which is true. But, Davey, children belong to the same species as their parents and grand parents... and so on, if there isn't any mutation.

It is also a fact that, the thousand species that are supposed to belong to the same "kind" all have a different copy (at least) of each gene (except highly conserved ones).

That is incorrect, and the error pervade the entire thread. The molecular clock is primarily due to cell replication, not generation time.

To me, generation time is very important. A substitution rate per nucleotide per year should be proportional to :
mutation rate (per nucleotide per replication) * number of replications during gametogenesis * 1/generation time (per year)
I don't have any figure to show, but I think that generation time would be the term that varies the most between closely related species.

Your formula implies the neutral substitution rate would be inversely proportional to generation time. This is not accurate, nor a correct statement of the molecular clock hypothesis (though there is some correlation! ).

Assuming organisms have the same metabolic rate, then their gametes (esp. in males) would be predicted to mutate at a similar rate. The original molecular clock hypothesis was that they would therefore accumulate the same number of neutral substitutions per time — whether that was within a single organism or several descendent organisms. Hence, though an elephant may have only a single generation to the mouse's twenty, they would still accumulate the same number of mutations somewhere in the germ line. This is the baseline prediction.

The hypothesis has since been modified. Metabolic rates are not constant over species, which, in vertebrates, is correlated to size and generation time. (There are also lots of other anomalies and corrections, including questions about neutrality.) The fact that there is some corrective correlation with generation time has led to some misunderstanding of the molecular clock hypothesis.

That's exactly what my formula says.
I just assumed there wasn't much difference in mutation rates (per nucleotide per replication) and in the number of mitosis during gametogenesis, compared to the huge differences in generation times. I don't have the numbers, though.
Regarding metabolic rates, I learned it was negatively correlated with body size, at least in mammals. Small mammals spend more energy to maintain their temperature, partly because they have a small volume:surface ratio, and respiration produces free radicals which are mutagenic.

EDIT: that's what the abstract of the PNAS paper says.

We'd be well on our way, yes.  And I don't think that day is too far away ... did you read the article on the Future of Industrial Automation? (Instead of just pooh pooh it like our professor friend did)

So Dave, if Thomas Edison could have built a simple machine that was capable of building a duplicate of itself (which frankly wouldn't have been hard, even with 19th century technology), he would have created life in the lab?

If a machine is capable of duplicating itself by incorporating without our help elements of its environment, and is also able of producing slightly altered copies, then it could evolve and anything could happen.
I would be a living being to me. Organic molecules, cells, metabolism... don't matter to me. If something can reproduce and evolve indefinitely, it's alive or I don't see the fundamental difference.

This is just nonsense. Where do you think this "pre-existing variabillity" come from? Do you also believe that the first replicating entity will be a diploid, sexually reproducing organism with 23 pairs of chromosomes?

And facts disprove your view. Ayala is refering to diversity within a population. But there are far more than 4 alleles at each nuclear locus among the average thousand of species which are supposed to descend from the same couple of individuals.
This is also a simple fact that post-zygotic isolation can't possibly evolve without at least two new mutations between populations.

When there is a conflict between units of selection (gene/individual/population), the gene always has the last word.
My position, like Dawkins', is that we can explain our perception of the living world more precisely if we consider that selection acts on genes.

I think you're setting youself up for some arguments from the evo-devo folks, but I especially appreciate this particular input in this thread, so thanks.

we now have both ends of the spectrum represented, and I expect eventually this will spark some heated debate.

I'd prefer to stick to specific papers rather than general discussion myself, so with that in mind, do you have a specific article you would like to champion, Jean?

It's not evo-devo, as far as I can't tell, rather some situations found in nature that have been explain by selection acting on gene, in spite of their deleterious effects on population growth and the fitness of other genes.

I haven't read this papers actually. But maybe the review paper on segregation distorters is a good start.

Perhaps I'm exposing my ignorance, but isn't Down Syndrome caused by chromosomal nondisjunction during meiosis rather than a duplication of the chromosome?

Of course, dt is wrong on this. First he confuses genetic code with genome, and it's not a chromosomal duplication, which would mean that a DNA replication would occure twice for a chromosome during one interphase in the germinal lineage.
Maybe there are genetical predispositions to nondisjunction, but an important factor is the age of the mother, which greatly increases the risk.

Rarely, a region of chromosome 21 will undergo a duplication event. This will lead to extra copies of some, but not all, of the genes on chromosome 21 (46,XX,dup(21q)).[11] If the duplicated region has genes that are responsible for Down syndrome physical and mental characteristics, such individuals will show those characteristics. This cause is very rare and no rate estimates are available.

Bring on the boasting!

In any case, it's not the duplication of a whole chromosome.

"Statistically speaking" means you lose, Dave. If the flood sorted fossils statistically, there would be exceptions. There are no exceptions.

Expect Dave to come with a couple of exceptions reported by some Woodmorappe or whoever, ignoring the fact that artifacts are extremely rare and can be explained.

Whereas this is Dave's prediction *snicker* of the geological column, from top to bottom. (We have to do this for him, since he apparently can't make anything of his hypothesis.)

- Flying animals  : pterosaurs, bats, birds, dragonflies...

- "Intelligent" terrestrial animals - cause you know, they climbed the moutains : mammals, ...?

- Swimming and floating organisms : plankton, fishes, cetaceans, ichtyosaurs, jellyfishes, ammonites,...

- Benthic organisms (sensus lato) that got immediately burried : plants and algae, most shells, cyanobacteria, crabs and trilobites, most terrestrial animals?...

Dave's position is untenable, especially for someone who supports common descent (well, given his recent comments, I'm not sure that he does).

He would have to demonstate that adaptations never happen, or that they're not the results of mutations, i.e changes in the genome.
Not to mention the countless instances of positive selection, revelated by phylogenetics and genome comparisons - for example humans vs other primates - that he will have to falsify.

Alternatively, he could prove that beneficial mutations are not explained by known laws of physics (i.e. not the result of stochastic events).

So Mr Hunter, you think that convergence is somehow problematic for the theory of evolution?
Well it's not, especially when it concerns gross morphology (body shape, etc).
Dolphins are like big fishes, aren't they?

Date: 2007/01/27 05:06:17, Link
Author: jeannot
It appears that Dr Hunter is confused in his argumentation. I’ll try to help him with my best English.

He seems to argue that convergence is a problem for the theory of evolution while, actually, he shows us that convergence is merely a problem for the inference of reliable phylogenies, which is a completely different issue.

Dr Hunter, if you want to use convergence as an argument against the ToE, you'll have to prove that convergent evolution is impossible. You haven't done anything of the sort, yet. We await.

Regarding the phylogenetic inference: yes, homoplasy (be it by convergence, reversion or parallelism) can be problematic. In fact, the whole field of cladistics aims at resolving issues due to homoplasy.  If hompoplasy didn’t exist, there wouldn’t be any researcher in phylogenetics, we would just use the good old principle of parsimony to infer phylogenies that would always be 100% accurate.
But how do we solves the problems?
First, we use our own experience and logic. We know, from experience, that some poorly defined traits like gross morphology can be extremely labile and cannot be used to support common ancestry (otherwise, dolphins would belongs to the fishes, wouldn't they?).
However, there are been confusions, especially in taxonomy, for example when defining the superclass of "pisces", separate from tetrapods, while in fact, we are more closely related to the trout than the trout is related to a shark. But the anatomy of the skeleton indicated us the correct topology. Sharks (chondrichthyes) don't have any bones, while humans and trouts (osteichtythes) do. The fish-like shape can be easily explained by the fact that fish have to swim, but why would humans and trouts have bones, if not by common ancestry?
Another way to get around homoplasy is using data from paleontology. We know, by the fossil record, that tetrapods evolved from particular osteichthyes, sometime in the Devonian,  while chondrichthyes (sharks) already existed. It confirms us that tetrapods and other osteichthyes share a more recent ancestor than osteichtyes and chondrichthyes.
Lastly, we now mainly resort to DNA sequences to infer phylogenies. In this case, all characters (nucleotides) are considered equal. Homoplasy is still common, but researchers have defined models of evolution which are used to detect the most probable tree. And those trees, with a very few exceptions, confirm the phylogenetic relationships that were established thanks to anatomy and paleontology (chondrichthyes and osteichthyes for instance).

I hope that helps.

A niche does not cause an adaptation. <snip>


Are you trying to say that there is some kind of law preventing evolution from creating superficially similar animals?

Dr Hunter's view is not accurate. The environment "causes" the adaptation to a particular niche, by selecting mutations.

Now, as I said, he just has to prove that morphological convergences are impossible, even if they result from different mutations.

I also would like to know his hypothesis. First, do placentals and marsupials share a common ancestor?

But more on the topic, fundamentaly, I think UD is right. Everyone should have access to scientific results. This is what science is all about: knowledge. But in theory, nothing prevents a scientist from showing publicly his/her results (on a website for instance).
Actually, the acess to research journals isn't that much restricted. Every university has a subscription to a variety of journals, and grants the access to its students.

Things are not always as they appear.  Darwinists may not hold a monopoly of knowledge after all.  Could it be that Creationists might just be right about a thing or two?

Damned!

That the tree of life is “messy” at the bottom lends credence to the notion that horizontal gene transfer played a much more significant role in pre-cellular life than was previously thought.

When an where did those early and massive horizontal gene transfers happened?

AFAIK, the three empires (Archea, Bacteria and Eukaryotes) are clearly delimited using the data from 16S rRNA genes. Why should we suppose some HGT? Are there some discrepancies with phylogenies relying on other sequences?
The ancestors of LUCA can't be known, and if some HGT occurred before the split, we can't detect them, unless I'm completely mistaken.

Help me, Zach.

The Three Domain Hypothesis has been under stress for quite some time, starting with mitochondrial resemblance to symbiotic bacteria.

There's still a lot of uncertainty — and undoubtedly more surprises still to come. Remember, scientists are trying to reconstruct events from billions of years ago based only on very fragmentary evidence. Genomics is still in its infancy.

Yes I know about endosymbiosis. I was thinking about nuclear genes (at least in eukaryotes).
It seems there were some massive genetic transfers between archea and bacteria.

BTW-does anyone know why Darwin is always cited and not Wallace

The story of Darwin and Wallace is actually very interesting. Darwin had been marshalling evidence for his Theory for more than 20 years when he received a letter from Wallace outlining a very similar theory, writing to Lyell that "he could not have made a better short abstract!" Lyell and Hooker arranged for Darwin's and Wallace's theories to be presented to a meeting of the Linnaean Society in 1858. However, Darwin's theory was far more developed and the publication of Origin of Species the following year changed biology forever. Wallace freely admitted to Darwin's scientific priority.

That's a good thing, I suppose; imagine having to listen to the creos calling us "Wallacians" and defenders of "Neo-Wallacism". Ew.

Darwin is to 'darwimp' as
Wallace is to....

If anybody cares, over at dawkins.net our old buddy AFDave Hawkins has finally given in and agreed to a formal debate with Deadman_932.

http://richarddawkins.net/forum/viewtopic.php?t=10675

The topic is "The Global Flood of Noah described in the Biblical Book of Genesis is a real, historical event and is well supported by the empirical evidence."

DM has already made his opening post, everyone is waiting on Davie to show.

It's a brave new world for Davie - no evading questions, no quote-mining, no equivocating of definitions.  In other words, all his usual tactics are strictly verbotten.

There's a spectator/comments thread already going too.  Lord help me but I'm afraid it's gonna be like watching a tweetybird get run over by a 400 HP riding mower.

To Deadman, if he's still with us:

Since AFDave can't ignore your questions in a formal debate, would you keep one of your 50 posts for this: http://en.wikipedia.org/wiki/Seafloor_spreading
This completely debunks his hypothesis, and is also impossible to explain with the common YEC arguments (the alleged non-reliability of isotopic dating won't do). I haven't seen any YEC try to adress this observation yet, and of course, Dave kept ignoring it.

Thanks in advance.

Bible-based criticism of evolution, once limited to Protestant fundamentalists in the United States, has become an issue in France now that Pope Benedict and some leading Catholic theologians have criticized the neo-Darwinist view of creation.


"...has become an issue" is vastly overstating the case. ID/Creationism has not impinged at all on mainstream French media and virtually nobody I ask has ever shown any awareness or interest in the topic.

Indeed, Intelligent Design is hardly discussed, even among evolutionary biologists in France. And when it is, we refer to what's happening in the US.
No one is going to support ID/creationism in the French media unless he/she wants to look like a complete idiot. Not that everybody here supports evolution, though...
I've even heard of a female paleontologist who twists her research data to fit her views about some sort of prescribed evolution. It's strange that JAD, who is well aware of any sciencist that wrote a single world against Darwin, never mentioned her.

But interpretation comming from creationists are just that, post-observational interpretations. No hypothesis, no prediction, no comparison to observation.

Dogs are possibly the most widely varying species on the planet while still remaining a single species. In 20,000 years of artificial selection and preservation of variants that never would have survived in the wild there hasn’t been a single variant with an anatomical feature not characteristic of canines nor has a new species of dog emerged.

It depends on your definition of "species". I'm sure some dog races are unable to reproduce with wolves.

Domestication has led to distinct specices. That's the case for a few crops, namely cultivated pea, broad bean, and even lentil (if I'm not mistaken), to name only legumes. They are never found in the wild. They have been completely differentiated from their wild ancestors, in just 10000 years of agriculture or less.

Zachriel, the fun with the type of theologists you just quoted is their strange sense of seeing poetry and beauty in nature. I understand that and I even find them touching.

What I don't understand is the fact that, for them, nature will lose its poetical beauty if this beauty is explained by natural laws. i.e: if nature is so beautiful (even for humans that are part of it), it can't just be natural.
That's a complete nonsense.

Hi,

This thread may sound a bit like the recent "where are you from" thread, but I’d like it more focused on your relationship with ID and other forms or creationism/anti-evolutionism. In other words, why are we here to discuss such topics?
I heard that some of us are evolutionary biologists, so their conflict with IDC would be clear. However, many of us are not biologist, and I would be curious to know the reasons why they became interested in this political/cultural debate.

I am from France, where creationism has lost all credibility for over a century, but I often heard, from a distance, that it was a more (vaguely) threatening movement in the US. But I never paid much attention to it. Though I’ve always been sort of fascinated by such ignorance and blindness.
I specialized in evolutionary biology 2.5 yeas ago, when I began my master. At this time, I never heard of “Intelligent Design”. This was before a mail was delivered in a mailing list (of a local association of evolutionary biologist) which related the event of one of the few ID paper that was published in a Peer review journal-the one by Steven C Meyer, in the proc. Of Washington-and the reaction that followed in Nature and Science. I first got intrigued, but I didn’t go any deeper in the topic at that time, though I read part of the paper.
Then, there was this mess around those sticker that were to be put on biology textbooks, in Arkansas I believe (or was it somewhere else?), and that were supposed to aid student keep an open mind about what was just a theory, evolutionary theory of course. I heard the news in a discussion board, the ars technica discussion board for those of you who know the site. I was amazed to witness the heated discussion between creationists (that were in minority) and defendant of science. Hopefully, ars technica is populated with educated people.
Then I became interested in the debate. Mostly, I was just a lurker, because most of the time, I dare not post comment in English (and this is also very time consuming for me), by I found that witness creationist’s argument being debunk in public very entertaining. People often resort to links toward talk origins, I then discovered the panda’s thumb.
Then I just googled for a real discussion board (not a blog), where creationism could be discussed, but among educated people; and google returned antievolution.org, the critique resource. I first though it was a anti-evolution website.
When I registered to the board, the most prolific topic was featuring Ghost of Paley and his gut to gamete / geocentric theory.
Meanwhile, I began my PhD on evolutionary ecology in a species of aphid, and I followed kitzmiller vs dover with moderate attention.
I’ve found here a bunch of fine people (most of you), and a few amusing jerks (AFDave, JAD…). I particularly appreciate the (now defunct) AFDave CGH and the uncommonly dense discussion thread, particularly, the erudition of Zach, the fun tidbits reported form UD by Phonon, the hilarious dt parody by Richard, Arden, Steve and others. I wish I could participate a bit more, but I mostly don’t have the time nor the motivation to post in English.

John Pye Smith (head of Homerton Divinity College)
Hugh Miller (self taught geologist, and editor of the Free Church of Scotland's newspaper) and,

Not that I am strictly answering your assertion, I don't have the time to check ISI for "papers in the literature that calculate the thermodynamics underlying the formation of nucleic acids through abiogenetic processes."

Anyway, I'm not sure whether Stanley Miller calculated any delta(G) after his famous experiment. This won't change the fact that he produced 13 amino acids through abiogenetic processes, and that there is no "room for reasonable doubt" regarding the respect of the second law, as you seem to suggest in another thread.

If you think that, just because he didn't calculate delta(G), 13 amino acids may have been produced in opposition to the second law, you are not being reasonable.

Do you honestly think there may not have been enough energy available in the prebiotic Earth to drive NA formation? Do you think it's such an uncertainty that we need to calculate whether it's possible according to SLOT?


If such a calculation exists I'd like to see it.

For example, the magnitude of temperature in the local environment plays a key role in determining whether or not a reaction is spontaneous, especially when we're dealing with exothermic reactions that decrease entropy (not necessarily the case here, of course). Cytosine formation in sufficient concentrations, for example, is proposed to happen in cold environments. This possibly conflicts with the hydrothermal vent model.

Good study here.

Do all the prebiotic elements need to be produced at the same place?

Anyway, if we knew everything about abiogenesis, it wouldn't be an active field of research, don't you think?

Let me help you. the ToE predicts that one humain chromosome (pair) results from the fusion of two chromosomes that are found in other great apes. The fusion would leave a signature in the chromosomal structure (two centromeric patterns instead of one).
There is no way for a chromosome to be completely lost between apes and humans, this would be lethal for a zygote, according to the theory.
So if every chimp chromosome is found to have its homologue in humans, expect for the one that is missing in our cells, which would have no equivalent, this would mean that one has just disappeared. Since it's not possible according to the ToE, such observation would falsify the theory.
And guess what, human chromosome 2 has been shown to result from the fusion of two chromosomes.

FTK - There is a famous quote: "a rabbit in the Cambrian" would falsify TOE.....


No it wouldn't.  I've read lots of stuff about out of place fossils.  There is also soft dinosaur tissue found in 70,000,000 year old fossils to contend with.  

No matter....just a fucking fluke.  Evolutionists start whipping out just-so stories right and left.  Happens all the time.

A single fossil wouldn't be sufficient to falsify the ToE since a mistake is always possible, but recurrent findings of mammals (for instance) in the middle of precambrian fauna would pose a BIG problem for the theory.

And the ToE makes no prediction about the conservation of soft tissue over time. You're confused.

Jeanot - Thank you yes, you are correct, and a Big Thank You to oldmainthesky too, for expressing my point much better than I did!

For the record, the joke about the precembrian rabbit is from JBS Haldane, unless I'm mistaken.

Name one. Just one. And please, please, no "polystrate" trees.

I'm pretty sure that AIG has a couple of "misplaced fossils". I'm also pretty sure that those artifacts have been easily explained.

Let, uh, the celebrations begin! Somebody get Kristine in here to shimmy triumphantly or something.

"UncommonDescent" is now a doubly embarrassing blog title.

EDIT: Oh,  man. And while we're on the topic of exciting evolutionary discoveries: Chinese researchers seemed to have pinpointed the gene mutation that distinguishes our cognitive abilities from that of apes. I feel overwhelmed. Overwhelmed with evidence.

Discuss!

Scientists may have found a gene mutation that distinguishes us from apes. There are likely to be many genes involved, and many non-protein-coding regulatory regions.

[creo monde ON]

Oh yeah, but were those mutations RANDOM?

Well, the common descent of humans has never been denied by creationists.

Really?  Cool... I must have missed it.  Can you link me to the response from Wes in regard to my questions about biblical literalism?  Thanks.

Now that you're not being evasive anymore, can you tell me what peer-reviewed articles on evolution you've read?

And if she offers a way to falsify ID while she's at it, it would be a world's first.

It seems to me these two situations are not comparable.


I don't see why not.  Whenever a creationist or an IDist talks about science, you people consistently accuse them of having a religious agenda.  

Excuse me, do you imply that you were talking about science?
Where?

Excuse me, I though you were answering Arden about the current "situations".

You mean you were referring to, say, AFDave or some other creo at the panda's thumb for instance?

Per PaV's comments here:

http://www.uncommondescent.com/evolution/survival-of-the-rarest/

I ran some experiments with GAs and cyclical fitness functions as well as instances where the population itself effects the fitness functions.

A website illustrating the effects of cyclical fitness functions on GA populations and the possibility of the population itself producing a cyclical progression in a genetic algorithm can be found here:

http://www.duke.edu/~pat7/public/htm/oscillatingGA.html

these are still preliminary.  i'd like to hear comments or questions, but i'll be out of touch for a few days.  enjoy...

The frequency of a trait can influence its own fitness, yes (it's called soft selection and frequence dependence) but PAV is dead wrong.  Not only this doesn't hinder natural selection, but it has been remarkably observed in the wild, confirming models and the ToE in general.

A simple illustration of this is sex ratio, which should be biased toward females in respect to population fitness.
However, a trait increasing the frequency of the less frequent sex in progeny is favoured (because individuals of the rare sex are fitter, being able to mate more). That's why sex ratios in panmictic populations are 1/1.

For a more specific exemple, see the peculiar lizard Uta stansburiana.

Similarities is evolutionists strongest point of contention, yet you forget a few things. Scientists are to the point of declaring ALL mutations to DNA detrimental to the organism.  This keeps in line with the second law of thermodynamics.
