Some have suggested that homosexuality has evolved as a form of natural population control. There are several problems with this idea. Population control is not necessarily a good thing for the survival and propagation of a population. If there is a population of humans, such as a tribe or a country, Overpopulation will create demand for resources. Because of this, a populous group of organisms will be driven to conquer other areas, and would then have more resources, which would then further increase said group's population. Ergo, groups that can more rapidly increase their population are more evolutionarily successful.
