长期的实地研究表明，雄性黑猩猩，Pan troglodytes，在几种情况下附属和合作。假设男性之间的密切遗传关系，亲和和合作行为已被假设为通过亲属选择的间接影响。我们测试的假设，母系遗传相关性影响男性的社会联系和合作模式，在一个异常大的社区的黑猩猩在Ngogo研究地点，基巴莱国家公园，乌干达。实地观察表明，23名成年男性之间的联系和合作的六个行为措施显着相关。线粒体基因组第一高变区的序列显示，三对男性和一个五联体共享线粒体DNA单倍型。矩阵排列测试使用的行为和遗传数据表明，男性的附属和合作，彼此没有密切的关系，通过母系。这些发现增加了越来越多的经验证据，表明亲属关系在构建社会群体内野生黑猩猩行为模式方面起着辅助作用。版权所有2000动物行为研究协会。
Long-term field research has revealed that male chimpanzees, Pan troglodytes, affiliate and cooperate in several contexts. Assuming close genetic relationship among males, affiliative and cooperative behaviour have been hypothesized to evolve through the indirect effects of kin selection. We tested the hypothesis that matrilineal genetic relatedness affects patterns of male social affiliation and cooperation in an unusually large community of chimpanzees at the Ngogo study site, Kibale National Park, Uganda. Field observations indicated that six behavioural measures of affiliation and cooperation among 23 adult males were significantly correlated with each other. Sequences of the first hypervariable portion of the mtDNA genome revealed that three pairs of males and one quintet shared mtDNA haplotypes. Matrix permutation tests using behavioural and genetic data showed that males that affiliated and cooperated with each other were not closely related through the maternal line. These findings add to a growing body of empirical evidence that suggest kinship plays an ancillary role in structuring patterns of wild chimpanzee behaviour within social groups.
