Just because some animals simulate sex with members of the same sex, or actually perform some sort of same sex act, no light is shed on human behavior or morality.
Many animals eat their own young, others' young, eat excrement, never wear clothes, they never ever grow food or cook it, only some are monogamous, they often commit incest with mothers/fathers/sisters/brothers/sons/daughters, and no animals ever question their purpose or meaning of life. They have no religious beliefs, philosophy, or morality.
So just because some animals jump on members of the same sex we should emulate them?
but in a way you proved the point of those who believe it is genetic........all the things you pointed to are genetic dispostions of animals, almost all their behaviors are, so in essence what i'm asking is , is this homo behavior like your examples, genetic aberrations.......I"m not advocating one way or the other, but as a studier of behavior, I'm curious since if it is not a genetic abberation, who taught them this behavior?
