[This four part series responding to Paul Gross can be seen in: Part 1, Part 2, Part 3, Part 4.] An urban legend has cropped up among Darwinists that Michael Behe ignores indirect routes of evolution, commonly called “exaptation,” when he argues for irreducible complexity. In his review of The Edge of Evolution in The New Criterion, anti-ID biologist Paul Gross wrongly accuses that “Behe had failed to understand ‘exaptation’ (the use of an available part in function ‘B’ despite its original function ‘A’).” But in Darwin’s Black Box, Behe clearly accounts for exaptation and explains why it does not refute irreducible complexity: “Even if a system is irreducibly complex (and thus cannot have been produced directly), however, one can Read More ›

[This four part series responding to Paul Gross can be seen in: Part 1, Part 2, Part 3, Part 4.] In Paul Gross’ review of The Edge of Evolution he wrongly claims Behe’s argument for design is merely a negative argument against evolution. Gross asserts that Behe argues for ID by “offer[ing] some claim that Darwinism is wrong, with the (unwarranted) conclusion that life is therefore the work of an intelligent agent.” (emphasis in original) This misrepresents Behe’s argument. Behe does not say that because Darwinian evolution has flaws, therefore intelligent design is proven correct. As Behe writes in the afterward to the new edition of Darwin’s Black Box: [I]rreducibly complex systems such as mousetraps and flagella serve both as Read More ›
