What role does homosexuality have in human evolution

Why didn't the genes that lead to homosexual development die off very quickly in the evolutionary development of our species? 


The fact that people are still born homosexual, despite what I'm guessing to be years of evolutionary push back, leads me to believe that homosexuality plays a necessary (or at least interesting) role in our societal structures or ????

It's important to remember that the idea of a 'homosexual person' is a relatively recent, extremely social construct - even though homosexual behaviour is very natural (and as has been said, has been seen a lot in the animal kingdom) the idea of exclusive homosexual pair bonding or similar is not at all common - most likely, if our ancestors (say, great great great etc uncle fred) engaged in homosexual behaviour, he would likely also engage in heterosexual behaviour opportunistically - you can see what this might have been like by studying our closest living relatives, bonobos , who engage in a lot of homosexual activity (but still mate in a heterosexual manner).

Culturally the idea that a person can be 'a homosexual' rather than just participating in homosexual acts is very new - except for the last 200 years or so 'homosexual' as a concept didn't really exist, particularly not as applied to women - it's important not to look at evolutionary history with sociology goggles on.
