Mechanism of Nature, less dogmatic after all

Jerry Fodor has written an interesting piece about some modifications concerning the theory of evolution in Nature ("Why pigs don't have wings"). Darwin's powerful idea that selective forces are the reason for what Nature is might not be as true as it first appears: some characteristics of individuals might just come for no specific reason or deep principle. Because even in the mechanism of Nature, life is also full of surprises and the road is just full of irrational bumps.

Paradoxically, that would make a lot of sense in many cases.
