re: Genes
I've heard it postulated that back in the day, when the men would go out to hunt, that would leave the women relatively defenseless.
Now they could leave a male behind, but how do you know he's not tupping your woman? The Selfish Gene would not allow that.
Unless, you know he is gay.......
If memory serves me right, Desmond Morris had a few things to say about it in the Naked Ape, including mention of several animal species (e.g. foxes) where some of the animals in a group exhibited homosexual tendencies.
