Recently, biochemist Michael Behe published an article in Quarterly Review of Biology, titled “Experimental Evolution, Loss-of-Function Mutations and ‘The First Rule of Adaptive Evolution’,” arguing that “the most common adaptive changes seen … are due to the loss or modification of a pre-existing molecular function.”
So, not only must the long, slow process of Darwinian evolution create every exotic form of life in the blink of a geological eye, but it must do so by losing or modifying what a life form already has.
Anyway, Behe reviews the last four decades of work on experimental evolution in bacteria and viruses (phage), and finds that nearly all the adaptive mutations in these studies fall into classes 1 and 3. We see very few “gain of FCT” mutations. Although this is not my field, the review seems pretty thorough to me, and the conclusions, as far as they apply to lab studies of adaptation in viruses and bacteria, seem sound.
It looks as though Coyne must now actually take Behe’s argument seriously.
Of course, he should have a long time ago, but for years Darwinists were happy to let trolls lob insults and profanity. Somewhat the way a deadbeat curses the bank officer who knows he hasn’t got the goods.
