This is an interesting theory. But i think that procriating is much more useful than bonding between the same sexes. Also, people don't have to be homosexual to be friends with others the same sex as them.

I think that there wasn't much culture at all for the predominant time in which human evolution took place.
Another riddle is why do homosexuals still exist nowadays if they clearly have lesser chances of procreating throughout their lives. Evolution would eventually have gotten rid of them. Unless one doesn't need to have any homosexual relative to be have the genetic tendency to be a homosexual himself? Or maybe, there is no such thing as "genetic predisposition" to be a homosexual, but i doubt there isn't.
