社会融合程度较高或社会经济地位较高的人寿命较长。最近对非人类灵长类动物的研究表明，这种模式与人类模式惊人地一致：拥有更多社会伙伴、更强的社会联系或更高的统治地位的雌性灵长类动物都寿命更长。然而，目前还不清楚社会环境是否也预测了非人类灵长类动物的生存，就像在男性中一样。这种差距之所以持续存在，是因为在大多数灵长类动物中，雄性分散在社会群体中，导致许多雄性失踪，命运不明，出生日期不明。我们提出了一个贝叶斯模型来估计随时间变化的社会协变量对特定年龄的成年死亡率在两种性别的野生狒狒的影响。我们比较了两性的生存轨迹如何与一生中的社会关系和社会地位联系在一起。我们发现，与雌性狒狒相比，与雌性狒狒联系更紧密的雄性狒狒寿命更长。然而，在他们的年龄中具有较高统治地位的男性似乎寿命较短。这一发现为雄性狒狒的异性恋社会纽带的适应意义带来了新的理解：除了保护雄性狒狒的后代不被杀害外，这些纽带可能对雄性狒狒本身有直接的好处。这篇文章是“灵长类动物衰老过程的演变”主题的一部分。
People who are more socially integrated or have higher socio-economic status live longer. Recent studies in non-human primates show striking convergences with this human pattern: female primates with more social partners, stronger social bonds or higher dominance rank all lead longer lives. However, it remains unclear whether social environments also predict survival in male non-human primates, as it does in men. This gap persists because, in most primates, males disperse among social groups, resulting in many males who disappear with unknown fate and have unknown dates of birth. We present a Bayesian model to estimate the effects of time-varying social covariates on age-specific adult mortality in both sexes of wild baboons. We compare how the survival trajectories of both sexes are linked to social bonds and social status over the life. We find that, parallel to females, male baboons who are more strongly bonded to females have longer lifespans. However, males with higher dominance rank for their age appear to have shorter lifespans. This finding brings new understanding to the adaptive significance of heterosexual social bonds for male baboons: in addition to protecting the male's offspring from infanticide, these bonds may have direct benefits to males themselves. This article is part of the theme issue ‘Evolution of the primate ageing process'.
