Richard Dawkins, in keeping with the contemporary liberal credendum, assumes that there must be a gay gene. In this brief video he struggles valiantly to explain why the gay gene was not selected out of his Darwinian universe; it should have been, since homosexuals would not have reproduced.

His suggested answers are below and appear to have been extracted from the Beano Comic Book of Weird Science:

1. The gay uncle theory: a prehistoric gay equivalent of the eunuch who looks after the females and their offspring while the butch males are out hunting. They passed on gay genes to the children by protecting their relatives’ children who would have carried the gay gene, demonstrating – albeit tenuously -the Darwinian advantage of the protective gay uncle for cavemen; it doesn’t explain the last 6000 years.
2. The gay gene was passed on by homosexuals who had sex with the dominant males’ females on the side; homosexuality was used merely as a cunning ploy to steal other men’s’ women.
3. The gay gene only produces homosexual behaviour given the right social stimulation – such as today. Dawkins almost slips into blasphemy on this one by saying there is no gay gene; he quickly recovers by sputtering that there is a gay gene now even if it once used to be an animal tracking gene which wasn’t allowed to express itself properly. Of course, this leaves the original problem: once the gay gene expresses itself in gay behaviour, homosexuals would be selected out – they don’t seem to have been.

So there you have it: the great high priest of Darwinian Dogma has spoken; all nonsense perhaps, but atheists, please genuflect.
