Nature the observation of homosexual behavior in animals can be seen as both an argument for and against the acceptance of homosexuality in humans, and has been used especially against the claim that it is a peccatum contra naturam (sin against nature). Smaller and weaker bonobos often form pairs to defend themselves against stronger and larger male bonobos Female bonobos also show increased homosexual behavior during times of high tension and conflict 2 similar behavior is observed in bottlenose dolphins, acorn woodpeckers, japanese macaques, and even lions. But new research shows that even these indirect benefits are not required for the persistence of homosexual behavior in animals
