长期以来，人们一直假设群外冲突的威胁可以促进动物群体内社会积极行为和凝聚力的表达。我进行了一个比较分析的影响组间冲突（索引的家庭范围重叠）组内的隶属关系水平（索引的时间从事allorooming）在48个灵长类动物的样本。在系统发育广义最小二乘回归中，两个变量之间没有关联。我的结论是，组间冲突可能最好引起短期的立即变化的隶属关系的水平，但永久提升凝聚力似乎是人类特有的大规模的社会融合和扩大组间冲突。
It has been a longstanding assumption that the threat of extra-group conflict can promote the expression of socio-positive behavior and cohesion within animal groups. I conducted a comparative analysis on the effect of inter-group conflict (indexed by home range overlap) on within-group affiliation levels (indexed by time engaged in allogrooming) in a sample of 48 primate species. There was no association between the 2 variables in a phylogenetic generalized least squares regression. I conclude that inter-group conflict may at best elicit short-term immediate changes in affiliation levels, but permanently elevated cohesion appears unique to humans with their large-scale social integration and scaled up inter-group conflict.
