Now homosexuals can have children, so its not a true failure there, but it does lower ones desire to reproduce.

The answer is either sexuality is very fragile in development and can 'switch' quite easy, the genes themselves may be fragile, or there is a survival benefit to the species by having homosexuals in the population.

I don't know the answer, but my educated opinion is that sexual orientation is fragile in development AND there is a survival benefit.

One study showed that women who were enduring conditions like bombing etc in WWII were more likely to have homosexual babies. The theory it was the mother being under stress which caused it.

Now if you take that in a survival context, a population under stress may well need less males actively looking for mates, and at the same time those males would help out with their existing families. Having that gay uncle benefits everyone, while at the same time he is not producing children which would use up resources.

Just my theory.
