linkThat may be changing with the work being undertaken by Joan Roughgarden, a professor of biology at Stanford University who has written a book called Evolution's Rainbow.
Roughgarden, a transgender woman, has lived in the shadow of Darwin's long accepted theories on sexual selection along with most of her biological comrades who have always seen homosexual activity as some sort of anomaly.
"I was at a Gay Pride parade and I was just stunned by the sheer magnitude of the LGBT population. Because I'm a biologist, I started asking myself some difficult questions. My discipline teaches that homosexuality is some sort of anomaly. But if the purpose of sexual contact is just reproduction, as Darwin believed, then why do all those gay people exist?"
