Jerry Fodor and Massimo Piattelli-Palmarini argue that new genetic discoveries—namely that major differences between species may be less about the evolution of new genes than about the same genes being regulated and expressed in new ways—reveal the wrongness of Darwinism. But reviewer Kenan Malik writes that their understanding of Darwinism is "incoherent" and that they don't provide enough evidence to suggest a flaw in Darwin's fundamental argument of evolution by natural selection.
