Females usually remain in their natal groups throughout their lives, while males transfer to other groups at around the time of sexual maturity. Females maintain close bonds with maternal relatives. Adult females form linear dominance heirarchies, which remain relatively stable for considerable lengths of time. Relationships among males are usually more aggressive than those among females, perhaps because most males in a group are unrelated and because male reproductive success is largely determined by competition for females. The outcome of male competition is a dominance heirarchy, determined by fighing ability, age and size.

Other Comments One of the most interesting aspects in the lifestyle of olive baboons is the fact that friendships, mostly unheard of in animal species, have been noted. Barbara Smuts has studied these friendships. Certain males and females maintain very close bonds with each other, spending much time together feeding, grooming, resting, and copulating.
