In most primate groups emigration of the maturing young of one or the other sex tends to serve as an incest avoidance mechanism. Among most primate species it is the males who change groups. This supports the theory that, in terms of reproductive success, males should compete for mates and females should compete for resources. In hominoids the combination of increased longevity and greater female discrimination in mate selection seems responsible for female emigration. This may relate to the high frequency of patrilocality and male control of resources among human groups.
在大多数灵长类群体中，一性或另一性成熟幼崽的迁出往往充当一种避免乱伦的机制。在大多数灵长类物种中，是雄性改变群体。这支持了这样一种理论，即就繁殖成功而言，雄性应竞争配偶，而雌性应竞争资源。在类人猿中，寿命延长和雌性在配偶选择上更具歧视性这两者的结合似乎是雌性迁出的原因。这可能与人类群体中父系居住和男性对资源的控制频率较高有关。
