Find that hard to believe. I mean that even if what you say is true of our primitive ancestors, the same does not hold true today. There is absolutely no reason to suppose that the disappearance tomorrow of all forms of homosexuality would in any way reduce our reproductive fitness, not by any model presented - even if that model is valid.

"Absolutely no reason..?" OK, do you know the difference between "reproductive firness" and "Darwinian fitness?" In Darwinian fitness the "fittest" individual is the one who survives to have the most offspring that have the most offspring.

Studies (easy to find in that library you are going to visit) show that in rat populatiuons, same sex behaviors increase dramatically when poulation increases and space and food resources diminish.

As to modern Western culture: gay people reproduce, quite frequently. I have no studies, just have known a lot of gay folks. HOWEVER-

Neither you nor I know the imapact of 10-18% of the population suddenly becoming "straight." If even half of these people formed couples and produced 2.6 children in the next ten years, ... well, you do the math. What impact do you think there would be?
