Gay Animals and Evolution


Joan Roughgarden, a transgendered professor of biology at Stanford University, has penned a fascinating-sounding book on the evolutionary role of homosexuality called Evolution's Rainbow. This month's Seed magazine features a long article on Roughgarden's theories, which center on explaining why, if homosexuality is a genetic aberration, it hasn't been bred out of all species -- instead, homosexual coupling is more the norm than the aberration when it comes to most animals. As she says, "a 'common genetic disease' is a contradiction in terms, and homosexuality is three to four orders of magnitude more common than true genetic diseases such as Huntington's disease."

Male big horn sheep live in what are often called "homosexual societies." They bond through genital licking and anal intercourse, which often ends in ejaculation. If a male sheep chooses to not have gay sex, it becomes a social outcast. Ironically, scientists call such straight-laced males "effeminate."
Giraffes have all-male orgies. So do bottlenose dolphins, killer whales, gray whales, and West Indian manatees. Japanese macaques, on the other hand, are ardent lesbians; the females enthusiastically mount each other. Bonobos, one of our closest primate relatives, are similar, except that their lesbian sexual encounters occur every two hours. Male bonobos engage in "penis fencing," which leads, surprisingly enough, to ejaculation. They also give each other genital massages.

Basically, at the end of all her theories, she's saying that their are too many animals with homosexual behaviour, and it hasn't been bred out. So homosexual activities must have a purpose... mainly keeping the social order of the group together.

Maybe if Humans accepted gay sex and relationships, we mightn't be such a violent and sexually frustrated culture.
