Homosexuality and Natural Selection.

Obviously gene for homosexuality contradicts Dawkins concept of "selfish gene". Dawkins admitted that such a gene is not created by reccurent random mutation and he pointed out:

---

Genes that predispose a significant minority of men to homosexuality raise a Darwinian puzzle.

---

Dawkins himself about the problem:

quote:

---

If a homosexuality gene lowers its own probability of being reproduced today, and yet still abounds in the population, that is a problem for commonsense as much as for Darwin's theory of evolution. And, intriguing as several of these theories may be, I have to conclude that it remains a problem.

Dawkins equate darwinism with his "selfish gene" hypothesis to avert attack and to put resposibility of "selfish gene" to darwinism. Because homosexuality gene obviously cannot pass and replicate itself however selfish it is.

I skimmed the paper "Evidence for maternally inherited factors favouring male homosexuality and promoting female fecundity" link to which you have given above. The explanation of greater fecundity of mothers having X chromosome with homosexual gene seems to back up the idea of "selfish gene" also in this case. But you know I do not believe a "selfish gene" story a bit. Trying to find something else.
