Wonder what happened to the follow-up on this one:

Quote These translation products, called vector proteins, are functionless unless they form legible Chinese characters, in which case they serve the real
function of writing. This coupling of artificial genetic causation to the real world of language makes evolutionary experimentation possible in a context where innovation can have a richness of variety and a depth of causal complexity that at least hints at what is needed to explain the complexity of bacterial proteomes. In order for this possibility to be realized, we here provide a complete Stylus genome as an experimental starting point.

Kinda goofy, but they built a 70,000 word genome. Not a small amount of work. This was done and written up by May 2011. And then, did they try to 'evolve' it?

Guesses:
1) They did, it works, shhh....
2) DI gets into a fight: providing a fitness landscape is "smuggling information" in even though that is exactly what the environment does in evolution, crap our analogy defeats our point...shh
3) The Chinese speaker bailed
4) The bug evolved into the prolific writings of VJTorley, translated and dumped onto UD for us.

Quote (Freddie @ Feb. 12 2014,15:38)So glad this thread has gone active again ... super pictures these past few days.  Living here in the South of England, there's not much opportunity to get out right now unless you have a boat and like taking pictures of lakes.  

I bought myself a Canon 100mm f2.8 macro lens for Christmas, with an OEM ring flash (not an LED knock-off) so i've been playing around with that combination learning how to take macro shots.  

All of these are handheld at 1/200th with the flash, most I think are between f11 and f22 to get some decent depth given that the macro lens has an extremely shallow DoF at f8 and below.  This all makes for a challenge, of course.  I've now got a monopod coming in the post (by canoe, probably) just to hopefully increase the 'good' shot ratio.  Also ordered a macro slider so I can try out some focus stacked shots with my tripod.

These couple are from a frosty morning in early January.
Cool macros Freddie! I'm thinking about getting a similar lens myself. You've definitely got me thinking about it again with these!

Here's an Interesting and Worthwhile Scientific Volume Advocating, and Challenging, "Intelligible Design"

ARN ID Update - Wed, 2014-02-12 03:37

An endorsement on ENV of the book, which is a collection of philosophical, historical, mathematical, and scientific essays on design in nature. Many of the chapters are written by scientists from outside the United States, with Spain being especially well represented, who are friendly to intelligent design. However, not all of the chapters defend ID. Some of the authors critique ID, or claim it's impossible to scientifically detect design in nature. But even the criticisms are thoughtful, making this volume a worthy addition to anyone's collection of ID-related books.

A South Dakota senator on Thursday killed his proposal that would have allowed teachers to discuss whether a higher power played a role in creation, saying it was too poorly written to pass.

The Senate Education Committee voted to kill the measure, which sought to ensure teachers could tell students about intelligent design, the belief that a higher power must have had a hand in creation because life is too complex to have developed through evolution alone.

Scientism as expounded by the New Atheists

ARN ID Update - Sun, 2014-02-09 19:14

The past 10 years has witnessed the rise of New Atheism, particularly in the US and the UK, with leaders who write best-selling books and attract a vociferous following. No doubt the sociologists of science will come up with some interesting things to say about this movement, but it is highly significant that the New Atheists have created deep divisions within their own intellectual community. The latest salvo expressing discontent has been fired by Massimo Pigliucci, evolutionary biologist, philosopher of science and advocate of atheism. In an academic paper, Pigliucci argues that the term "new" does not have anything to do with the public advocacy of atheism. Nor is there novelty in the arguments they use to advance their atheistic claims. However, Pigliucci is able to identify two distinctive characteristics of the New Atheists:

"[The first] is to be found in the indisputably popular character of the movement. All books produced by the chief New Atheists [. . .] have been worldwide best sellers, in the case of Dawkins's God Delusion, for instance, remaining for a whopping 51 weeks on the New York Times best-seller list. While previous volumes criticizing religion had received wide popular reception (especially the classic critique of Christianity by Bertrand Russell), nothing like that had happened before in the annals of Western literature. [. . .]
[Secondly, W]hat I see as a clear, and truly novel, though not at all positive, "scientistic" turn that it marks for atheism in general. [. . .] [We will] explore some examples of what I term the "scientistic turn" that has characterized some (but not all) New Atheist writers (and most of their supporters, from what one can glean from the relevant social networks)." (p.144)


New atheists say they trust science, but they redefine science so it cannot lead them to recognise design in nature. (Source here)

It is the second of these characteristics that elicits protestation from Pigliucci: the New Atheists are advancing ideas that call for a firm rebuttal. There is a strong tendency for these new leaders to be rather disparaging of philosophical arguments and base their polemics on the claims that science is the exclusive route to knowledge and that the findings of science supports the atheist position. According to Pigliucci, their approach necessitates a re-defining of science, and he argues that the new definition is indistinguishable from scientism.

"The New Atheism approach to criticizing religion relies much more forcefully on science than on philosophy. Indeed, a good number of New Atheists (the notable exception being, of course, Daniel Dennett) is on record explicitly belittling philosophy as a source of knowledge or insight. Dawkins says that the "God hypothesis" should be treated as a falsifiable scientific hypothesis; Stenger explicitly - in the very subtitle of his book - states that "Science shows that God does not exist" (my emphasis); and Harris later on writes a whole book in which he pointedly ignores two and a half millennia of moral philosophy in an attempt to convince his readers that moral questions are best answered by science [. . .]. All of these are, to my way of seeing things, standard examples of scientism. Scientism here is defined as a totalizing attitude that regards science as the ultimate standard and arbiter of all interesting questions; or alternatively that seeks to expand the very definition and scope of science to encompass all aspects of human knowledge and understanding." (p. 144)

The paper discusses a great diversity of issues, but we shall note only comments relating to Richard Dawkins' The God Delusion. Two of the issues identified are: his discussion of morality without gods, and his tackling of "the god hypothesis" to show that science-based evidence allows the hypothesis to be rejected. Regarding morality without gods, Pigliucci is unimpressed. Not only does Dawkins pass over the Greek philosophers, he does not interact with more contemporary secular thinkers who have contributed to this issue. Pigliucci draws attention to the Euthyphro dilemma, which stimulates the question: Is an action moral because the gods decree it, or do the gods decree it because it is moral? Plato and Aristotle came to the view that morality takes precedent over divinity. Atheists make a distinction between religion and morality and argue that morality should not be based in the will of a god.

"When it comes to the issue of why being moral, however, Dawkins shows most clearly his limitations. For instance, he seems to be unaware of what many philosophers consider by far the most powerful argument in favor of the idea that gods and morality are entirely logically independent issues: the so-called Euthyphro dilemma posed by Plato in the homonymous dialogue from 24 centuries ago." (p.150)

What Pigliucci might have noted is that the Dawkins promotes the distinction between religion and morality even though he does not use philosophical arguments to justify it. This is why he (and new atheists generally) make frequent references to Old Testament practices, such as slaying enemies and keeping slaves, to show that our sense of morality is such that we would not want to worship the Old Testament God even if he exists. Pigliucci wants to rest his case on the arguments made by secularist moral philosophers; Dawkins wants to rest his case on a scientific assessment of what is morally right; but neither of them engage with the responses of Christian moral philosophers to the Euthyphro dilemma and the secularists, so resting their case appears somewhat premature. (For a brief response, see here. For some discussion, see here).

Turning to "the god hypothesis", Pigliucci acknowledges that Dawkins uses a scientific approach to "make ideas like a young earth, or the slightly more sophisticated concept of "irreducible complexity" championed by Intelligent Design proponents, clearly untenable". Whilst this smacks of spin to members of those groups, the essential point is that there are aspects of YEC and ID that can be addressed using the tools of science. But is the existence of God amenable to scientific investigation? Can God ever be the subject of a scientific hypothesis? Pigliucci thinks not.

"The real issue is that Dawkins (and most if not all of the New Atheists) does not seem to appreciate the fact that there is no coherent or sensible way in which the idea of god can possibly be considered a "hypothesis" in any sense remotely resembling the scientific sense of the term. The problem is that the supernatural, by its own (human) nature, is simply too swishy to be pinpointed precisely enough." (p.148)

No doubt, this challenge to Dawkins' thinking could be discussed further. It might make the point clearer if it was said that science deals with the behaviour of material things, and God is not material - but the Creator of material things. So science cannot put God under the microscope, nor can experiments be devised to test whether he exists. However, this conflicts with the premise of the new atheists that science is the only route to knowledge. Pigliucci draws together his objections to Dawkins' scientism with these words:

"To recap, then, what is considered to be perhaps the quintessential text of the New Atheism is an odd mishmash of scientific speculation (on the origins of religion), historically badly informed polemic, and rehashing of philosophical arguments. Yet Dawkins and his followers present The God Delusion as a shining example of how science has dealt a fatal blow to the idea of gods." (p.148)

The following quotes summarise the conclusions about scientism. They have already antagonised some of the new atheists and Pigliucci responds to their criticisms here. But more generally, these conclusions are relevant to all who have a stake in the scientific enterprise.

"1. Scientism is philosophically unsound. This is because a scientistic attitude is one of unduly expanding the reach of science into areas where either it does not belong [. . .] or it can only play a supportive role. [. . .] What I do object to is the tendency, found among many New Atheists, to expand the definition of science to pretty much encompassing anything that deals with "facts", loosely conceived. So broadened, the concept of science loses meaning and it becomes indistinguishable from just about any other human activity." (p.151)
"2. Scientism does a disservice to science. Despite representing a strong attempt to expand the intellectual territory, as well as prestige, of science, I think that scientism is detrimental to science in at least two ways: internally to the discipline itself, because it represents a misunderstanding of what science is and how it works, which is unlikely to serve well either practicing scientists or graduate students as scientists-in-training; externally because it has the potential of undermining public understanding and damaging the reputation of science." (p.152)
"3. Scientism does a disservice to atheism. Finally, I maintain that a scientistic turn does not do much good to atheism as a serious philosophical position to begin with, contra the obvious explicit belief of many if not all of the New Atheists." (p.152)

As well as drawing attention to the arguments presented in this paper, there are two issues worthy of highlighting here. The first has reference to the place of philosophy in developing an informed mind and a mature judgment. It is noticeable how the scientistic rejection of philosophy is gaining ground. In 2010, Stephen Hawking, in The Grand Design, announced that philosophy was "dead" because it had "not kept up with modern developments in science, particularly physics". A year ago, Lewis Wolpert took the side of scientism when discussing Hawking's views (video here). It is to science leaders like these that Pigliucci's essay is directly relevant. He boldly charges them with anti-intellectualism, because their ideology has made them closed minded about the work of others ploughing in different fields.

"Moreover, it seems clear to me that most of the New Atheists (except for the professional philosophers among them) pontificate about philosophy very likely without having read a single professional paper in that field. If they had, they would have no trouble recognizing philosophy as a distinct (and, I maintain, useful) academic discipline from science: read side by side, science and philosophy papers have precious little to do with each other, in terms not just of style, but of structure, scope, and range of concerns. I would actually go so far as to charge many of the leaders of the New Atheism movement (and, by implication, a good number of their followers) with anti-intellectualism, one mark of which is a lack of respect for the proper significance, value, and methods of another field of intellectual endeavor." (p.152)

The second issue is one where I consider Pigliucci to have underplayed the influence of Darwinism on the rise of atheism. In presenting a historical perspective on atheism, the intellectual leaders are identified as philosophers. This is indicated in the following sentence:

"Even in the twentieth century, that is, before the early twenty-first century advent of New Atheism, the ball was still firmly in the philosophical park when it came to defense of or apologia for atheism: just consider the writings of A. J. Ayer, John Dewey, and, naturally, Bertrand Russell." (p.146)

The impact of Darwin's theory on the acceptance of atheism needs a more thorough discussion than is provided in the paper. Pigliucci does acknowledge that science is not irrelevant to atheism.

"On the contrary, atheism makes increasingly more sense the more science succeeds in explaining the nature of the world in naturalistic terms. After all, Hume's arguments against intelligent design were devastating, but he lacked an alternative explanation for the appearance of design in nature, and it was Darwin that provided it. Indeed, I think the Hume - Darwin joint dispatching of ID is an excellent example of how naturalism - qua philosophical position - is the result of the inextricable link between sound philosophy and good science." (p.152-3)

This quote refers to naturalism rather than atheism, and this is to be commended. Before Darwin, we had the Enlightenment, whereby naturalism replaced Christian Theism as the philosophical stance of scientists. Naturalism led to a wave of religious scepticism - but this was expressed within a Deistic worldview. Most of the Enlightenment scholars were still impressed by the pervasive evidences of design and they reconciled this with naturalism by allowing a creative act at the beginning. However, Darwinism brought immense changes - not to the naturalistic philosophy of science (which was already widespread), but in sweeping away Deism (which was perceived as a god-of-the-gaps blunder). Darwinism then made it possible to be an intellectually-fulfilled atheist, which is what has set Dawkins on his journey to new atheism.

Pigliucci rightly points out that science cannot be extended to cover all aspects of knowledge. However, in calling for a tighter definition of science, he needs to give greater emphasis to the philosophical underpinnings of science. A science that presumes naturalism MUST necessarily end up as an atheistic science. It fails as science because this approach presumes what it then claims science has confirmed. This means that naturalistic science is not objective and is not able to follow the evidence wherever it leads. For example, this is why the advocates of abiogenesis focus their efforts on chemical evolution, as this is the only avenue that naturalistic science permits researchers to follow. Consequently, the information characteristics of life are underplayed and they hope for information to arise by currently unknown emergent processes. The evidence however, points to complex specified information being fundamental to life, which naturalistic science cannot concede. By contrast, theistic science does not prescribe or predetermine outcomes, but it can handle natural processes as well as recognise intelligent agency. We will make progress when multiple working hypotheses can be tested without prescribing philosophical presuppositions for science. This is where education should be heading, not enforcing naturalism as the essence of science.

New Atheism and the Scientistic Turn in the Atheism Movement
Massimo Pigliucci
Midwest Studies in Philosophy, 37 (1):142-153 (2013)

Abstract: The so-called "New Atheism" is a relatively well-defined, very recent, still unfolding cultural phenomenon with import for public understanding of both science and philosophy. Arguably, the opening salvo of the New Atheists was The End of Faith by Sam Harris, published in 2004, followed in rapid succession by a number of other titles penned by Harris himself, Richard Dawkins, Daniel Dennett, Victor Stenger, and Christopher Hitchens.

The Ham-Nye Creation Debate: A Huge Missed Opportunity

ARN ID Update - Thu, 2014-02-06 03:15

Casey Luskin of the Discovery Institute gives his take on the debate. "Ham talked about some science here and there, but almost all of what he said focused on trying to support a young earth viewpoint. Since he's not a scientist, the great majority of his arguments amounted - over and over again - to "Because the Bible says so." Nye's main argument was, "Because the evidence says so," and he cited a lot of reasonable evidence for an old earth. While Ham did make a few effective points that you don't have to accept evolution to do good science, the compelling scientific evidence for design in nature got skipped over".

Regulatory codes hidden within exons

ARN ID Update - Tue, 2014-02-04 21:43

Redundancy in the genetic code has long been recognised. Most amino acids can be specified in multiple ways (2-6 synonymous codons). More recently, it has also become known that synonymous codons are non-random, stimulating thought as to why this should be (see here). Since codon usage biases characterise both prokaryotic and eukaryotic genomes, is it possible that they are accidents of evolutionary history? This seems to be ruled out by pervasive evidences of conservation. Since the biases are not removed by mutations, it is inferred that "observed codon preferences in mammalian genomes [. . .] appear to be under selection" (p.1367.) Such a conclusion is reached by deduction from evolutionary theory. If specific (synonymous) codons do not matter when manufacturing proteins, is it possible they are relevant to the regulation of genetic processes? Since there is a presumption favouring simplicity in the minds of most geneticists, this research question has only recently been taken up. There are many synonymous codons when coding for proteins, but are they synonymous if they are also coding regulatory instructions?

"Genomes also contain a parallel regulatory code specifying recognition sequences for transcription factors (TFs), and the genetic and regulatory codes have been assumed to operate independently of one another and to be segregated physically into the coding and noncoding genomic compartments. However, the potential for some coding exons to accommodate transcriptional enhancers or splicing signals has long been recognized." (p.1367)


The challenge of the Human Genome Project has given way to searching for an understanding of multiple overlapping genetic codes. (source here)

With the availability of large amounts of genome data, it is possible to test many hypotheses relevant to the functionality of DNA sequences. The data set used is impressive:

"To define intersections between the regulatory and genetic codes, we generated nucleotideresolution maps of TF occupancy in 81 diverse human cell types using genomic deoxyribonuclease I (DNaseI) footprinting. Collectively, we defined 11,598,043 distinct 6- to 40-base pair (bp) footprints genome-wide (~1,018,514 per cell type), 216,304 of which localized completely within protein-coding exons (~24,842 per cell type). Approximately 14% of all human coding bases contact a TF in at least one cell type (average 1.1% per cell type), and 86.9% of genes contained coding TF footprints (average 33% per cell type)." (p.1367)

A summary of the main findings of the research team is provided in a Perspectives essay by Weatheritt and Babu. The hypothesis of two co-existing codes is fully justified by the evidence. According to the press release: "scientists were stunned to discover that genomes use the genetic code to write two separate languages."

"How widespread is the phenomenon of "regulatory" codes that overlap the genetic code, and how do they constrain the evolution of protein sequences? Stergachis et al. address these questions for the transcription factor-binding regulatory code. They use deoxyribonuclease I (DNase I) footprinting to map transcription factor occupancy (a protein bound to DNA can protect that region from enzymatic cleavage) at nucleotide resolution across the human genome in 81 diverse cell types. The authors determined that ~14% of the codons within 86.9% of human genes are occupied by transcription factors. Such regions, called "duons", therefore encode two types of information: one that is interpreted by the genetic code to make proteins and the other, by the transcription factor-binding regulatory code to influence gene expression. This requirement for transcription factors to bind within protein-coding regions of the genome has led to a considerable bias in codon usage and choice of amino acids, in a manner that is constrained by the binding motif of each transcription factor." (p.1325)

Weatheritt and Babu go further. They suggest a general principle: that redundancy in the genetic code opens the door for, not one, but many regulatory codes that can operate within protein-coding regions of the genome. One research question of the future is: how many overlapping codes can be tolerated by the genetic code?

"This "binding" code joins other "regulatory" codes that govern chromatin organization, enhancers, mRNA structure, mRNA splicing, microRNA target sites, translational efficiency, and cotranslational folding, all of which have been proposed to constrain codon choice, and thus protein evolution." (p.1325)

It should be noted that these research findings do not tell us what binding a transcription factor actually achieves. The field of gene regulation is in its infancy. The research team notes that TF binding "may serve multiple functional roles" but that their analysis is "agnostic" to this functionality. Weatheritt and Babu conclude:

"The investigation of overlapping codes opens new vistas on the functional interpretation of variation in coding regions and makes it clear that the story of the genetic code has not yet run its course." (p.1326)

This discussion of genetic codes is only meaningful if it is recognised that the genome is a carrier of complex specified information. The essence of life is not to be found in chemistry, but in the information carried within the cell. Chemicals are used to carry biological information, but the chemicals are not themselves information. The research team recognises this when they say:

"Our results indicate that simultaneous encoding of amino acid and regulatory information within exons is a major functional feature of complex genomes. The information architecture of the received genetic code is optimized for superimposition of additional information and this intrinsic flexibility has been extensively exploited by natural selection." (p.1371-2)

There is a problem with the last few words of the above quotation. The flexible information architecture is said to be exploited "by natural selection", yet this claim has not emerged from a study of evidences. Rather, the theoretical framework of neo-Darwinism provides the context for interpreting the evidences, so that all signs of complexity and functionality are automatically associated with the operation of natural selection. Yet, we have no evidence to show that natural selection can either produce or refine complex specified biological information.

There is a perfectly viable alternative hypothesis to consider: that biological information is evidence for intelligent agency. The evidence we have already about the genetic code is sufficient to make the point, but new evidences of overlapping codes add weight to the hypothesis. The genetic code with redundancy overlaps with other regulatory codes in ways that test the ability of molecular biologists (intelligent agents) to understand what's happening, let alone write overlapping codes of their own as a biomimetic exercise. From time to time, leading biologists get the message, but seem at a loss to drive it forward.

"Any living being possesses an enormous amount of "intelligence", very much more than is necessary to build the most magnificent of cathedrals. Today, this "intelligence" is called "information", but it is still the same thing. It is not programmed as in a computer, but rather it is condensed on a molecular scale in the chromosomal DNA or in that of any other organelle in each cell. This "intelligence" is the sine qua non of life. If absent, no living being is imaginable. Where does it come from? This is a problem which concerns both biologists and philosophers and, at present, science seems incapable of solving it." Pierre Grasse, Evolution of Living Organisms: Evidence for a New Theory of Transformation, (New York: Academic Press, 1977, 2).

The decision to endorse a naturalistic explanation rather than advance agnosticism about the origins of hidden overlapping codes is a pointer to hidden ideologies in origins-science. It seems that as long as materialism/naturalism is presumed, then a great number of unwarranted assertions (usually linked to Darwinism or abiogenesis) go unchallenged in academic papers. As soon as it is pointed out that only intelligent agents write codes, there is an outcry that science is being subverted by religious fundamentalists. However, the converse is true: intelligent design theory is based on the evidence of complex specified information. The evidences for naturalistic alternatives all evaporate under close scrutiny.

Abstract: Genomes contain both a genetic code specifying amino acids and a regulatory code specifying transcription factor (TF) recognition sequences. We used genomic deoxyribonuclease I footprinting to map nucleotide resolution TF occupancy across the human exome in 81 diverse cell types. We found that ~15% of human codons are dual-use codons ("duons") that simultaneously specify both amino acids and TF recognition sites. Duons are highly conserved and have shaped protein evolution, and TF-imposed constraint appears to be a major driver of codon usage bias. Conversely, the regulatory code has been selectively depleted of TFs that recognize stop codons. More than 17% of single-nucleotide variants within duons directly alter TF binding. Pervasive dual encoding of amino acid and regulatory information appears to be a fundamental feature of genome evolution.
