In a darwinist aspect I suppose exclusive homosexuality isn't.
There are many studies showing that homosexuality in nature actually helps animals, for example at primate homosexuality seems to be a social skill that allows to keep the peace in exchange for sex. In order for a species to survive, all you need is for the members to have sex. There does not need to be a preference for heterosexuality. For example, I am a gay male. Within my lifetime I will have thousands of sexual encounters with a few men. If I engage in heterosexual coupling just twice and each time a child is born, I will have helped continue the species. The point being is that all a species needs is random sex. Historically, there has been a bias in researchers to only identify heterosexual behaviors. Only recently have animal biologist begun to count same-sex sexual pairing. Lo and behold, what do they find? Most animals don't have a preference toward heterosexuality. They just bump each other and occasionally it is opposite-sex behavior. Homosexuality is a natural evolutionary tendency.
