In ENV, Jay Richards opines that "host Neil deGrasse Tyson and the Cosmos producers have enshrouded this basic science with the same materialist narrative we've come to expect. Pre-modern peoples universally see false patterns and portents in the heavens, and invariably see the irregular specter of comets as portents of doom. We get the stereotypical contrast between a "prescientific world ruled by fear" - signaled by a cartoon drawing of a malevolent figure wearing a bishop's miter - and the emergence of modern science, which finally delivered us from such obscurantism."
"This way of framing the history of science, however, requires a great deal of distortion and misrepresentation, especially when it comes to the figure of Isaac Newton. With Newton, the Cosmos writers encountered a dilemma: Either ignore his frankly religious and theistic view of reality, or misrepresent and compartmentalize it. They chose the latter course.
ScienceDaily reports "New findings show that much of the mineral from which bone is made consists of 'goo' trapped between tiny crystals, allowing movement between them. It is this flexibility that stops bones from shattering."
"Latest research shows that the chemical citrate - a by-product of natural cell metabolism - is mixed with water to create a viscous fluid that is trapped between the nano-scale crystals that form our bones. This fluid allows enough movement, or 'slip', between these crystals so that bones are flexible, and don't shatter under pressure. It is the inbuilt shock absorber in bone that, until now, was unknown."
Here is the review of the first episode of Cosmos by Casey Luskin of the Discovery Institute. The next two episodes have not been much better.
"If there was any doubt that the rebooted Cosmos series...would be politically charged and have a materialistic ideological message, consider what viewers saw in its first 60 seconds. The initial opening featured President Obama, with the Presidential Seal in the background, giving a statement endorsing the new series praising "the spirit of discovery that Carl Sagan captured in the original Cosmos." That's not necessarily bad, except for what happened next. Immediately following President Obama's endorsement, the show replayed Carl Sagan's famous materialistic credo from the opening of the original Cosmos series, stating: "The cosmos is all that is, or ever was, or ever will be." Does it violate the separation of church and state for the President of the United States to be portrayed seemingly officially endorsing Sagan's materialistic philosophy? Is this what President Obama intended when he promised in his first inaugural address to "restore science to its rightful place..."
I bought and read "The Explanation for Everything" by Lauren Grodstein a few months ago. I hoped it would be a balanced approach to the debate. I was sorely disappointed.
Now, Kelley J. Unger of Discovery Institute has read the book, and provides a great review: "I've just read a new fiction book that has won praise from critics, Lauren Grodstein's The Explanation for Everything. In the marketing materials provided by Algonquin Books, the author is lauded for not taking sides in the evolution debate. She says herself that she wants to "figure out why people believe what they believe." But as one reads the book it's evident that she is indeed taking sides, doesn't fully develop why her characters believe what they believe, and certainly hasn't fully investigated the theory of intelligent design."
In this post in Uncommon Descent I (Eric Anderson) want to consider a fundamental aspect of intelligent design theory: the concept of "information'.
This is centrally relevant to the intelligent design concept of "complex specified information". Attempts have been made by ID critics to derail ID by critiquing each of these three words: complexity, specification and information. Indeed, it is not uncommon to see long, drawn-out, battles over these terms in an attempt to avoid getting to the central issue of whether design can be detected.
In ENV, Casey Luskin writes that..."Jerry Coyne is playing more games, constantly pretending that we have "admitted" intelligent design is religious when we criticize Ball State University (BSU) for being "anti-religious." In his post, Coyne was responding to a letter I published in the Muncie Star Press explaining the anti-religious nature of the book What's Your Dangerous Idea?."
A branching pattern of variation was central to Darwin's concept of speciation. As one population of organisms follows one trajectory, another population may spin off in a different direction. When they are sufficiently far apart, they are considered to be separate species. The Galapagos finches have been regarded as exemplars of Darwinian transformation, even leading to the claim that one newly developed population is "behaving as a separate species". However, the most recent study, from one of the smaller islands (Floreana), concludes that the most likely cause of the disappearance of one of these species is hybridization.
"The authors suggest that hybridization may have been responsible for the disappearance of the large tree finch from Floreana, and that it may now be causing the remaining two species to fuse into one: speciation in reverse." (p.179)

Until recently, three species of tree finch were known from Floreana Island. Morphological differences noted were limited to body size and beak dimensions. Their names are the small tree finch, the medium tree finch, and the large tree finch. They are found living together in several other Galapagos islands. Now Kleindorfer and colleagues report that the large tree finch has disappeared from Floreana. The remaining two species are affected by hybridization.
"The analyses also revealed that individuals that do not fit into either population show intermediate characteristics, suggesting that they are hybrids. Consistent with the hypothesis of ongoing hybridization on the island, the authors observed females of the morphologically larger group (the medium tree finch) pairing with males of the smaller group, and they identified 15% of yearling males in 2010 as hybrids." (p.170)
Most of the researchers appear to think that their studies are probing the essence of speciation, and are providing the empirical evidence that supports the Darwinist claim that natural selection acting on inheritable variation is the key to understanding the origin of species. Peter and Rosemary Grant say that these studies are "Uniquely valuable in showing how speciation is done" (p.179). Kleindorfer et al. say that research programmes over "the past 2 decades have transformed our understanding of the ecological context of processes that underpin speciation" (p.325). With specific reference to the new findings, they write:
"The results presented here go to the heart of evolutionary biology: by what criteria do we denote species, and by what criteria do new species form or collapse? Here we present evidence that three sympatric species of Darwin's tree finches in the 1900s have collapsed, under conditions of hybridization, into two species by the 2000s. The proportion of yearling hybrid birds increased from 0% in 2005 to 14.6% in 2010, indicating a potential for elevated hybrid fitness in this system. [. . .] There is widespread agreement that the benefits of hybridization include increased genetic variance that facilitates novel evolutionary trajectories in changing environments." (p.334)
Whilst the new research is a useful contribution to knowledge, the results do not go to "the heart of evolutionary biology". The reason is that the important questions to do with diversity in the living world relate to the origin of biological information. What factors and processes are relevant to building novelty and complexity? The finches of Floreana Island are distinguished by very minor morphological differences, and the observed changes tell us nothing about the origin of new biological information.
Please can we have some realism from researchers adhering to the Darwinian paradigm. In the main, their research findings cast light on ecology but they are failing to touch the real challenges facing evolutionary biology. This assessment of their work is now appearing in mainstream peer-reviewed literature and in articles written by influential scientists. Here is a comment from Professor John Dupre, who is Director of the ESRC Center for Genomics in Society, University of Exeter.
"Further destabilizing evolutionary theory is the growing realization that many factors, not just the genome, determine an individual organism's development. Ironically, as the discovery of DNA's structure - initially lauded as the final act in the triumph of the new synthesis - led to a better understanding of genomes' functioning, it ended up weakening belief in their unique role in directing biological development. Those who long deplored the omission of development from evolutionary models - a decades-old critique made under the scientific banner of evolutionary developmental biology ("evo-devo") - together with the insistence that organisms' development draws on a wide variety of resources, have been vindicated.
"Recent developments in molecular biology have put the final nail in the coffin of traditional genetic determinism. For example, epigenetics - the study of heritable modifications of the genome that do not involve alterations to the genetic code - is on the rise. And the many kinds of small RNA molecules are increasingly recognized as forming a regulatory layer above the genome.
"Beyond undermining the gene-centered theories of evolution that have dominated public consciousness for several decades, these developments call for new philosophical frameworks. Traditional reductionist views of science, with their focus on "bottom-up" mechanisms, do not suffice in the quest to understand top-down and circular causality and a world of nested processes."

Of the greatest urgency is attention to educational textbooks. For too long, the Darwinists have maintained a hegemony that resists all critiques of their arguments. Typically, they present any questioning of their interpretation of the evidence as religiously motivated and anti-science. For the good of science, this situation has to change.
Species Collapse via Hybridization in Darwin's Tree Finches

Abstract: Species hybridization can lead to fitness costs, species collapse, and novel evolutionary trajectories in changing environments. Hybridization is predicted to be more common when environmental conditions change rapidly. Here, we test patterns of hybridization in three sympatric tree finch species (small tree finch Camarhynchus parvulus, medium tree finch Camarhynchus pauper, and large tree finch: Camarhynchus psittacula) that are currently recognized on Floreana Island, Galapagos Archipelago. Genetic analysis of microsatellite data from contemporary samples showed two genetic populations and one hybrid cluster in both 2005 and 2010; hybrid individuals were derived from genetic population 1 (small morph) and genetic population 2 (large morph). Females of the large and rare species were more likely to pair with males of the small common species. Finch populations differed in morphology in 1852?1906 compared with 2005/2010. An unsupervised clustering method showed (a) support for three morphological clusters in the historical tree finch sample (1852?1906), which is consistent with current species recognition; (b) support for two or three morphological clusters in 2005 with some (19%) hybridization; and (c) support for just two morphological clusters in 2010 with frequent (41%) hybridization. We discuss these findings in relation to species demarcations of Camarhynchus tree finches on Floreana Island.

Hybridization can cause two species to fuse into a single population. New observations suggest that two species of Darwin's finches are hybridizing on a Galapagos island, and that a third one has disappeared through interbreeding.
At ENV, there will be more to say about Seth MacFarlane's revival of the Carl Sagan vehicle for scientific materialism after we've seen it. In the meantime, you may wish to have access to the antidote handy before grappling with the ailment itself.
