No place for gay-bashers on the Planet of the Apes

Slate:

Homosexual behavior has been documented in hundreds of animal species, but the same does not hold for gay-bashing. For starters, few animals are exclusively gay. Two female Japanese macaques might have playful sex with each other on Tuesday, then mate with males on Wednesday. Pairs of male elephants sometimes form years-long companionships that include sexual activity, while their heterosexual couplings tend to be one-night stands. For these and many other species, sexual preferences seem to be fluid rather than binary: Gay sex doesn’t make them gay, and straight sex doesn’t make them straight. In these cases, the concept of homophobia simply doesn’t apply.

Researchers believe that gay sex is even rewarded in certain species. For bonobos, sexual activity serves as an instrument of social harmony: It reinforces bonds and keeps the peace. For instance, when a female bonobo migrates into a new group, she often ingratiates herself to the clan’s other ladies by having a lot of sex with them. Far from being shunned, this homosexual behavior is welcomed. And former Stanford researcher Joan Roughgarden has argued that among male bighorn sheep bisexuality may be the norm; those that don’t participate end up as outcasts.
