Who says homosexuality is a human thing? We fans of the gay penguins in Manhattan's Central Park Zoo (who recently adopted an egg and are raising the baby happily, btw) know that animals can be in a fully committed gay relationship, just like humans. But ANW didn't know that Zebra Finches also swung in that direction, until this article: http://www.bbc.co.uk/nature/14479670
If gayness in the animal kingdom is not enough proof that some are simply "born this way," then what is?
