Mondo said: The point I see is that biology is destiny. We don't choose our sexual orientation.
That's how it appears to work in Nature. Sexual orientation is not chosen.
Homosexual behavior in animals refers to the documented evidence of homosexual and bisexual behavior in animals. This article covers non-human species, for homosexuality in humans, see Homosexuality. Such behaviors include sex, courtship, affection, pair bonding, and parenting among same sex animals. A 1999 review by researcher Bruce Bagemihl shows that homosexual behavior has been observed in close to 1,500 species, ranging from primates to gut worms, and is well documented for 500 of them. Animal sexual behavior takes many different forms, even within the same species. The motivations for and implications of these behaviors have yet to be fully understood, since most species have yet to be fully studied. According to Bagemihl, "the animal kingdom [does] it with much greater sexual diversity including homosexual, bisexual and nonreproductive sex than the scientific community and society at large have previously been willing to accept." Current research indicates that various forms of same-sex sexual behavior are found throughout the animal kingdom. A new review made in 2009 of existing research showed that same-sex behavior is a nearly universal phenomenon in the animal kingdom, common across species. Homosexuality is best known from social species.
The observation of homosexual behavior in animals can be seen as both an argument for and against the acceptance of homosexuality in humans, and has been used especially against the claim that it is a peccatum contra naturam ('sin against nature'). For instance, homosexuality in animals was cited in the United States Supreme Court's decision in Lawrence v. Texas which struck down the sodomy laws of 14 states. Whether animal sexuality has logical, ethical, or moral implications in human sexuality is also a source of debate (see appeal to nature).
