社会融合和社会支持可以对人类生存产生深远影响。这种现象在非人类动物中的程度在很大程度上是未知的，但这种知识对于理解寿命和社会性的进化很重要。在这里，我们报告的证据表明，亲和的社会行为（即“社会联系”）的水平与同性和异性同种预测成年野生雌性狒狒的生存。在肯尼亚的安博塞利生态系统中，与成年雄性或成年雌性有社会联系的成年雌性狒狒比与两性都有社会联系的雌性狒狒活得更长-与两性个体都有强烈联系的雌性狒狒活得最长。女性的社会联系，男性预测的优势地位高，表明男性是女性的有限资源，女性竞争获得男性的社会伙伴。迄今为止，只有少数动物研究发现社会关系可能影响生存。这项研究扩展了这些发现，通过研究两性之间的关系，这是迄今为止对任何动物进行研究的最大数据集。我们的研究结果支持了这样一种观点，即社会对生存的影响在社会性哺乳动物中是进化保守的。
Social integration and support can have profound effects on human survival. The extent of this phenomenon in non-human animals is largely unknown, but such knowledge is important to understanding the evolution of both lifespan and sociality. Here, we report evidence that levels of affiliative social behaviour (i.e. 'social connectedness') with both same-sex and opposite-sex conspecifics predict adult survival in wild female baboons. In the Amboseli ecosystem in Kenya, adult female baboons that were socially connected to either adult males or adult females lived longer than females who were socially isolated from both sexes-females with strong connectedness to individuals of both sexes lived the longest. Female social connectedness to males was predicted by high dominance rank, indicating that males are a limited resource for females, and females compete for access to male social partners. To date, only a handful of animal studies have found that social relationships may affect survival. This study extends those findings by examining relationships to both sexes in by far the largest dataset yet examined for any animal. Our results support the idea that social effects on survival are evolutionarily conserved in social mammals.
