在许多哺乳动物物种中，社交性对雌性的适应性有积极影响。在雌性狒狒中，社交融合度最高的个体繁殖最为成功。在此，我们检验了一些从亲缘选择理论推导出的关于成年雌性狒狒社会关系强度的预测。我们的分析基于对肯尼亚安博塞利盆地7个不同社会群体中的118只雌性狒狒在16年期间梳理毛发和交往模式的系统观察。这些群体中的雌性与近亲，包括它们的母亲、女儿以及母系和父系姐妹，形成了最紧密的关系。雌性也强烈地被与自己年龄相近的雌性所吸引，也许是因为同龄者往往是父系姐妹。在母亲死后，雌性与母系姐妹的关系会加强，而与姨母的关系则会减弱。此外，当没有近亲母系亲属时，雌性会与父系姐妹形成更紧密的关系，并且它们会通过与非亲属建立紧密关系来弥补近亲的缺失。综上所述，这些数据表明社会关系在雌性的生活中起着至关重要的作用，建立和维持紧密社会关系的能力可能对雌性的适应性产生重要影响。
Sociality has positive effects on female fitness in many mammalian species. Among female baboons, those who are most socially integrated reproduce most successfully. Here we test a number of predictions derived from kin selection theory about the strength of social bonds among adult female baboons. Our analyses are based on systematic observations of grooming and association patterns among 118 females living in seven different social groups in the Amboseli Basin of Kenya over a 16-year period. Females in these groups formed the strongest bonds with close kin, including their mothers, daughters, and maternal and paternal sisters. Females were also strongly attracted toward females who were close to their own age, perhaps because peers were often paternal sisters. Females' bonds with their maternal sisters were strengthened after their mother's deaths, whereas their relationships with their maternal aunts were weakened after their mother's death. In addition, females formed stronger bonds with their paternal sisters when no close maternal kin were available, and they compensated for the absence of any close kin by forming strong bonds with nonrelatives. Taken together, these data suggest that social bonds play a vital role in females' lives, and the ability to establish and maintain strong social bonds may have important fitness consequences for females.
