Thanks Cybele. I just posted links to some of the info I was discussing above. Vasey's article is interesting - he produces 5 testable hypotheses to explain why homosexuality evolved.<quoted text>
I think she made a valid point though. If homosexuality can be observed in animals, why would we be any different? Talk about animal instincts. Damn bonobos!
I disagree with him on terminology, though. I think we should call it same sex sexual behavior so as to be specific in what we are discussing - not a sexual identity, but behavior.
