“[T]here is in fact nothing that can alleviate that fatal flaw in Darwinism” says Professor Behe, stating the book’s central claim in the mendaciously mislabelled creationist web journal Evolution News.
The claim is clickbait, the book title misleading, and the argument long since rebutted. The historical roots of the argument show the close links between what now calls itself Intelligent Design, and biblically inspired “creation science”. The issues are important because the Intelligent Design movement gives a veneer of intellectual respectability to the denial of scientific reality. Read the rest of this entry
Michael Behe has a new book coming out, Darwin Devolves, which according to the mendaciously mislabelled Evolution News “Topples Foundational Claim of Evolutionary Theory.” I am unlikely to be sent a review copy, so I am relying on the Evolution News summary.
In brief, Behe continues to assert the existence of irreducible complexity in animal organs, while maintaining that
Darwinian evolution proceeds mainly by damaging or breaking genes, which, counter-intuitively, sometimes helps survival. In other words, the mechanism is powerfully de-volutionary. It promotes the rapid loss of genetic information.
and encapsulates this conclusion in what he calls the First Rule of Adaptive Evolution:
Break or blunt any gene whose loss would increase the number of offspring.
I reviewed Behe’s earlier statement of this Rule some years ago, in PandasThumb, and friends have suggested that I repost it. So here it is. (I am proud to say that it has already been reposted by Peaceful Science.
Since this First Rule of Adaptive Evolution, the pinnacle of Behe’s argument, was already spelt out in the earlier work, there is little that I need add to my original review below, beyond pointing out that even this puny statement of the obvious came with a debilitating disclaimer
It is called a “rule” in the sense of being a rule of thumb. It is a heuristic, useful generalization, rather than a strict law; other circumstances being equal, this is what is usually to be expected in adaptive evolution
and reminding Behe that he is himself the product of a massive increase in genetic complexity, the doubling and redoubling of the genome that separates him from his early notochord ancestors. The original review follows [note: in that review I referred to “E.Coli acquiring the ability to metabolise citrate under anaerobic conditions”; that should be “aerobic conditions, in the absence of a reducing agent”. h/t Monica Lewis. this does not, however, affect the logic of the argument]:
