Gay caveman found, what are your thoughts?

I've never thought of ity as a "trend," and I would appreciate a source for this gay caveman. How did they know he was gay? Also, I believe uality to be a combination of factors, but mively biological. There are many gay animals found in the wild, and this was probably just another case of how a creature was wired up to be. Gay is beautiful, just as any other form of love.
