"Trends in Ecology and Evolution, suggested that homosexuality among animals may be vital for the survival of the species." I find this hard to believe, considering reproduction is the only thing they have to survive.

Hey, You're being a bad google today, The 7 to 10% of the Gay population in any species, represents the same percentage of population that is not sustainable.

Now be a good google.

I've seen confused animals doing stuff. you know... "the dry hump" thing. But I still can't grasp this! I'll try to be good. It won't be easy but I'll try!
