Good points Sam.
I was wondering the same thing: What about female homosexuality? My theory - again, purely unscientific and unresearched - is along the same lines as the "group bonding" thing but with a slightly different twist.
My sense is that the mating process for female monkeys (just as an example) puts a great deal of stress on them, both psychologically and physically. So when they feel the desire to have a sexual encounter without all the huff and puff and bluster and aggression of a male (gawd, this REALLY sounds too human, doesn't it?
), they seek out a female. This may go some way in dispelling female-to-female aggressive tendencies in the group (especially when it comes to child-rearing) and further strengthen social bonds.
Interesting topic. I have some evolutionary biologist friends and I'm going to ask them about it.
