In my EvoBio class a decade ago, my professor told us the theory that homosexuality could be adaptive based on birth order because it would reduce fraternal rivalry: the family would have an additional adult to care for the young without being a reproductive competitor.

This doesn't make much sense, though. Every additional human is a very expensive investment of time, resources, and effort on the family, and offers no material return on investment for at least a decade in terms of productivity. True, while the gay son might not produce offspring to compete with his brother's kids, it also means he brings no additional mate and offspring to help out the family.
