Abstract

We assess the proposition that intergroup conflict (IGC) in non-human primates offers a useful comparison for studies of human IGC and its links to parochial altruism and prosociality. That is, for non-linguistic animals, social network integration and maternal influence promote juvenile engagement in IGC and can serve as the initial grounding for sociocultural processes that drive human cooperation. Using longitudinal data from three cohorts of non-adult vervet monkeys (Chlorocebus pygerythrus), we show that non-adults are sensitive to personal (age) and situational risk (participant numbers). The frequency and intensity of participation, although modulated by rank and temperament, both mirrors maternal participation and reflects non-adult centrality in the grooming network. The possibility of social induction is corroborated by the distribution of grooming during IGC, with non-adults being more likely to be groomed if they were female, higher-ranking and participants themselves. Mothers were more likely to groom younger offspring participants of either sex, whereas other adults targeted higher-ranking female participants. Although we caution against a facile alignment of these outcomes to human culturally mediated induction, there is merit in considering how the embodied act of participation and the resultant social give-and-take might serve as the basis for a unified comparative investigation of prosociality.

长尾猴群体冲突参与的社会诱导与发展轨迹。
我们评估了非人类灵长类动物群体间冲突(IGC)的命题,为人类群体间冲突及其与狭隘利他主义和亲社会的联系的研究提供了有用的比较。也就是说,对于非语言动物来说,社会网络整合和母亲的影响促进了青少年参与IGC,并可以作为推动人类合作的社会文化进程的初始基础。利用来自三个非成年黑尾猴(Chlorocebus pygerythrus)队列的纵向数据,我们发现非成年黑尾猴对个人(年龄)和情境风险(参与者数量)敏感。参与的频率和强度,虽然受到等级和气质的调节,既反映了母亲的参与,也反映了非成人在梳理网络中的中心地位。IGC期间的梳理分布证实了社会诱导的可能性,如果是非成人的女性、更高的职位和参与者自己,他们更有可能被梳理。母亲们更有可能培养更年轻的后代参与者,而其他成年人则更倾向于培养地位更高的女性参与者。尽管我们警告不要轻易将这些结果与人类文化介导的诱导联系起来,但考虑参与的具体行为和由此产生的社会让步如何作为亲社会性统一比较调查的基础是有价值的。
