Previous studies have shown that mammals, including primates, can recognize their paternal kin as individuals bias their social behavior to their paternal kin in comparison to unrelated individuals. In order to have the opportunity to interact not only with unrelated individuals, but also with paternal kin, an animal society would have to live, even if only temporarily, in stable multi-male multi-female groups where females mate with multiple males and male reproduction is highly skewed towards a few sires. The first aim of the present project is to investigate patterns of paternal kinship within and across groups in different species in order to predict the potential for selection for paternal kin bias. The second aim is to complete our knowledge of the mechanisms underlying paternal kin discrimination as the most likely mechanisms (familiarity and phenotype matching) are difficult to disentangle. The final aim of this project is to study potential cues such as similarity in odor, MHC, appearance, acoustics and/or personality which might be used by animals to identify paternal kin. The results of this study would provide an important contribution to our understanding of the impact of kinship on the evolution of social behavior in humans and other primates.

先前的研究表明，与无关的个体相比，包括灵长类动物在内的哺乳动物可以识别其父亲亲属将其社会行为偏向于父亲的亲属。为了有机会不仅与无关的个体进行互动，而且与父亲的亲戚互动，即使只有暂时的动物社会也必须生活在稳定的多男性多女性群体中，在这些群体中，女性与多个雄性和男性繁殖的女性相伴，高度倾斜了几个sires。本项目的第一个目的是研究不同物种内部和各组之间父亲亲属的模式，以预测选择父亲亲属偏见的潜力。第二个目的是完成我们对最可能的机制（熟悉度和表型匹配）的机制的了解，难以分解。该项目的最终目的是研究潜在的提示，例如气味，MHC，外观，声学和/或人格的相似性，可以用来使用动物来识别父亲亲属。这项研究的结果将为我们理解亲属关系对人类和其他灵长类动物的社会行为发展的影响提供重要贡献。
