Sean Carroll Fails to Scale The Edge of Evolution (Part IV): Mistaking Protein Sequence Similarity for Natural Selection

[Editor’s Note: This is Part 4 of a 4-part response. The full response can be read here.] In Part I of this series, I discussed Sean Carroll’s misrepresentations of Michael Behe’s arguments in The Edge of Evolution. Part II exposed a citation referenced by Carroll which, rather than refuting Behe, actually confirms him. Part III explained the fact that many of Carroll’s citations discuss meager examples of evolution that Behe finds fall well within the humble creative capabilities of Darwinian evolution. Carroll has thus far failed to engage Behe’s actual arguments. Carroll does make an attempt to tackle the origin of a couple complex biological features. Yet these attempts fail because they confuse the evidence for common descent from sequence Read More ›

Evolution for a Few or Evolution for Everyone? A Survey of Hypotheses about the Evolutionary Origin of Religion

Why did religion arise in the human species? Stanley Fish has a blog post at the New York Times observing that Richard Dawkins, “finds that the manufacturing and growth of religion is best described in evolutionary terms: ‘[R]eligions, like languages, evolve with sufficient randomness, from beginnings that are sufficiently arbitrary, to generate the bewildering — and sometimes dangerous — richness of diversity.’” Dawkins isn’t the only scientist who takes this kind of approach. David Sloan Wilson is getting a lot of attention these days regarding his views on the evolutionary origin of religion. Wilson is much more serious in his approach than Dawkins, but Wilson has been frank regarding how many academics view religion through an evolutionary perspective. In his Read More ›

Sean Carroll Fails to Scale The Edge of Evolution (Part III): Is Carroll Scared of Approaching the Edge of Evolution?

[Editor’s Note: This is Part 3 of a 4-part response. The full response can be read here.] In Part I of this series, I discussed how Sean Carroll’s review of Michael Behe’s new book, The Edge of Evolution: The Search for the Limits of Darwinism, misrepresents and oversimplifies Behe’s arguments. In Part II, I discussed the fact that one of Carroll’s citations actually confirms Behe’s argument that there is an edge to evolution, and that evolution tends to not proceed forward when additional mutations decrease functionality. In this installment, I will discuss how many of Carroll’s cited papers report types of evolution that Behe readily concedes can occur, and are unimpressive examples within the “edge” of evolution. It’s Easier to Read More ›

Sean Carroll Fails to Scale The Edge of Evolution (Part II): Carroll’s Citations Actually Confirm Michael Behe’s Arguments

[Editor’s Note: This is Part 2 of a 4-part response. The full response can be read here.] In my previous post, I explained how Sean Carroll’s review of Michael Behe’s book The Edge of Evolution badly misrepresented Behe’s arguments. Behe has responded to many of Carroll’s arguments here, but unfortunately for Carroll, it gets much worse. One paper Carroll cites in an attempt to refute Behe actually explicitly confirms Behe’s position that there are limits to the creative power of Darwinian processes. Carroll argues that Behe claims that “multiple-amino acid replacements therefore can’t happen.” In contrast to Carroll’s misrepresentation, Behe’s actual position contends evolution can proceed forward where there is a stepwise advantage gained with each mutation, but Behe also Read More ›

Sean Carroll Fails to Scale The Edge of Evolution (Part I): How Carroll Misrepresents Michael Behe’s Arguments

[Editor’s Note: This is Part 1 of a 4-part response. The full response can be read here.] A few months ago we discussed my review of Sean B. Carroll’s book The Making of the Fittest, the book in which Carroll intimates that the salvation of our species hangs upon accepting Darwin. Carroll has now invoked his own religious metaphors in his review of Michael Behe’s book The Edge of Evolution: The Search for the Limits of Darwinism in Science. While Michael Behe himself responds to Carroll here, I have a few comments which follow. Carroll postures himself as Thomas Henry Huxley debating Bishop Samuel Wilberforce in a famous 19th century debate over evolution. Carroll even opens the review by invoking Read More ›

Can Biology Textbooks Recover from Over-Praising Darwin?

They say that admitting a problem is the first step on the road to recovery. I’ll admit that I’m something of a bookaholic: I’m constantly picking up books, especially books on evolution. It’s been fascinating to read how Darwin is praised not only as the patron saint of “Western thought,” but sometimes as if he invented sliced bread and cupholders in cars. For example, Douglas Futuyma’s textbook Evolutionary Biology stated that “it was Darwin’s theory of evolution … that provided a crucial plank to the platform of mechanism and materialism–in short, to much of science–that has since been the stage of most Western thought.” John Dupré rejoices that “Darwin’s theory provides the last major piece in the articulation of a Read More ›

Pro-Darwin Biology Professor Laments Academia’s “Intolerance” and Supports Teaching Intelligent Design

Charles Darwin famously said, “A fair result can be obtained only by fully balancing the facts and arguments on both sides of each question.” According to a recent article by J. Scott Turner, a pro-Darwin biology professor at SUNY College of Environmental Science and Forestry in Syracuse, New York, modern Neo-Darwinists are failing to heed Darwin’s advice. (We blogged about a similar article by Turner in The Chronicle of Higher Education in January, 2007.) Turner is up front with his skepticism of intelligent design (ID), which will hopefully allow his criticisms to strike a chord with other Darwinists. Turner starts by observing that the real threat to education today is not ID itself, but the attitude of scientists towards ID: Read More ›

Will Darwinists try to pull a “Flock of Dodos” and Rewrite the History of Junk-DNA?

Junk-DNA is clearly going the way of the dodo, in more ways than one. The film Flock of Dodos has become a textbook example of Darwinists attempting to rewrite history to erase their past scientific and textbook mistakes. Now that we’re witnessing the apparent death of the “Junk-DNA” Neo-Darwinian paradigm, some pro-Darwin bloggers are already trying to rewrite history by claiming that Neo-Darwinism never supported the “junk-DNA” hypothesis after all. As one Scienceblogger wrote, “If you read evolgen you know that the term ‘Junk DNA’ is crap. From an evolutionary viewpoint it also seemed a bit peculiar to relegate most of the genome to non-functional status…” Just how valid is that statement? In 1995, Scientific American plainly expounded that under Read More ›

Dual-Coding Genes “Nearly Impossible by Chance” — How Would Francisco Ayala Respond?

We mortals are easily impressed by palindromes — words or phrases that have the same spelling forwards and backwards. But try writing a sentence which has two different meanings: One meaning is gained when you start with one letter of the first word, and then an entirely different meaning is understood when you start reading with the second letter of the first word. Such a sentence would be most impressive, but what if such “sentences” existed in our DNA? Leading evolutionary biologist Francisco Ayala recently wrote in Proceedings for the National Academy of Sciences (PNAS) that “Chance is an integral part of the evolutionary process.” Ayala then explained why he thinks Darwinian evolution is right and ID is wrong: “Biological Read More ›

Intelligent Design and the Death of the “Junk-DNA” Neo-Darwinian Paradigm

Two recent news articles are discussing the death of the junk-DNA icon of Neo-Darwinism. Wired Magazine has an article pejoratively titled “One Scientist’s Junk Is a Creationist’s Treasure” that emphasizes the positive point that intelligent design has made successful predictions on the question of “junk-DNA.” The article reports: [A] surprising group is embracing the results: intelligent-design advocates. Since the early ’70s, many scientists have believed that a large amount of many organisms’ DNA is useless junk. But recently, genome researchers are finding that these “noncoding” genome regions are responsible for important biological functions. The Wired Magazine article then quotes Discovery Institute’s Stephen Meyer explaining that this is a prediction of intelligent design that was largely unexpected under neo-Darwinian thought: “It Read More ›
