生物系统的持久性需要能够促进稳定性的进化机制。具有凝聚力的灵长类社会群体是稳定的生物系统的一个例子，尽管经常发生冲突，但这种系统仍然存在。我们认为，遗传亲缘关系及其相关的亲属关系结构是灵长类社会群体稳定的潜在来源，因为亲属关系结构在许多动物社会中是一项重要的组织原则。我们研究了7个圈养猕猴群体的48个母系家系的平均遗传亲缘关系对母系梳理稳定性和激动性相互作用的影响。具有低平均遗传亲缘关系的母系表现出更高的家庭水平的不稳定性，例如：在其母系新郎网络中有更多的亚群，更频繁地与亲属打架，以及更高的伤害率。一个群体内多个母系的家庭一级的不稳定与群体一级的不稳定进一步相关，例如伤害增加。恒河猴群体结构的稳定性似乎源于恒河猴群体中清晰的母系结构的存在，这种结构源于亲缘关系的凝聚力和相互竞争的相互作用。我们的结论是，遗传亲缘关系和亲缘关系结构是动物社会群体稳定的重要来源，特别是当优势和/或亲和互动通常由亲缘关系支配时。
The persistence of biological systems requires evolved mechanisms which promote stability. Cohesive primate social groups are one example of stable biological systems, which persist in spite of regular conflict. We suggest that genetic relatedness and its associated kinship structure are a potential source of stability in primate social groups as kinship structure is an important organizing principle in many animal societies. We investigated the effect of average genetic relatedness per matrilineal family on the stability of matrilineal grooming and agonistic interactions in 48 matrilines from seven captive groups of rhesus macaques. Matrilines with low average genetic relatedness show increased family-level instability such as: more sub-grouping in their matrilineal groom network, more frequent fighting with kin, and higher rates of wounding. Family-level instability in multiple matrilines within a group is further associated with group-level instability such as increased wounding. Stability appears to arise from the presence of clear matrilineal structure in the rhesus macaque group hierarchy, which is derived from cohesion among kin in their affiliative and agonistic interactions with each other. We conclude that genetic relatedness and kinship structure are an important source of group stability in animal societies, particularly when dominance and/or affilative interactions are typically governed by kinship.
