I've seen evolutionary explanations of acne, of gossiping, of ballroom dancing, the lot. It's a parlor game called name and explain. Just as for creationists, all this needs nothing more than belief. The infantile Darwinists are in a situation where they can't lose. If you find everything in the Bible or the Origin there's no point in doing science.
Evolution is to social scientists as statues are to birds.
It's a convenient platform on which to drop ill-digested ideas. It may be talked about in psychological conferences, but it is never mentioned in evolutionary meetings. I go to dozens of them. I've never seen any of its supporters at a scientific meeting about evolution, either. I'm doing it in part for Dr. Johnson's reason, which is that no man in his right sense has ever written except for money.
