In some primate species, such as the savanna baboon, the females can decide with whom they will mate, and they frequently choose males who exhibit strong male-female affiliation and parental behavior rather than male-male competition.

• 在一些灵长类物种中，例如黄狒狒，雌性能够决定她想与谁成其好事，她们挑选的雄性，往往是有异性亲和力、照顾孩子的，而不是好与同性打架的。
