“Experts have long argued that some dolphins aren’t heterosexual,” Benjamin Butterworth of Pink News reports. “Now a group of male dolphins have been caught having a gay orgy in Australia.”
The first book I bought and read about homosexuality among animals was Bruce Bagemihl’s Biological Exuberance: Animal Homosexuality and Natural Diversity (New York: St. Martin’s Press, 1999). It’s still a source when confronted by biological homophobia, which is not seldom used by “secular humanists” who want to defend their prejudice against gay people. Bagemihl provides a long list of animals where homosexual behaviour has been documented: ducks, penguins, dragonflies, beetles, dogs, sheep, birds, lizards, horses, cows, and so forth.
Bagemihl also provides examples for how these behaviours show sign of being important for the survival of the group, and thereby is an evolutionary advantage. One example that stuck in my mind is the common gulls, who have a system of adoption, where abandoned eggs are cared for by lesbians. Since a significant number of such birds are killed by other animals, the flocks with many lesbians are more likely to have their young survive. Another examples is wild dogs, where pups cared for by two males are more likely to grow big and strong because their two fathers find more food and are better at protecting the young than a lone female.
And still, some people continue to say that homosexuality is unnatural! It’s not, but homophobia is—no animals show sign of hating queer individuals.
