IMO I don't consider humans to be animals. We have more brains and should know better. Just cause the dumb animals do it don't make make it natural in our blood line. We split from the animals long ago. IMO most homosexual intention was behavioral problems early in childhood life or lack of affection by the other gender I assuming small percentage hormones got screwed up in the womb, which could explain the homosexual animals. I take it they didn't find out WHY animal specie went homosexual? Another thing just cause somebody studies and writes they're opinion on subject don't make it the absolute truth.
