In parts one and two, I showed that suggestions by some intelligent design advocates that evolutionary biologists have only recently become aware of widespread convergence are false. At least one ID proponent, though, has gone further, suggesting that convergence is a post hoc rationalization invented by ‘Darwinists’ to hide their dirty little secret that common descent is not supported by evidence.
Physicist Lee M. Spetner makes this argument in his book The Evolution Revolution. I don’t own The Evolution Revolution, but Casey Luskin has helpfully, and approvingly, quoted some critical passages:
Convergent evolution is the Darwinists’ lollapalooza. They made it up to keep their phylogenetic tree from falling apart, but they can’t say how convergence happens. — As quoted by Casey Luskin, 2014-10-19
