White-faced capuchins (Cebus capucinus) live in social groups comprised of extensive networks of both maternal and paternal kin - a demographic circumstance that is rare among mammals, but one that accentuates the importance of evolved mechanisms of inbreeding avoidance. Research on how such primates develop reproductive aversion toward certain individuals, and not others, will improve our understanding of these mechanisms and the limits of kin recognition in highly social animals. This project also will provide comparative work that may contribute to understanding the origins of, and variation in, incest avoidance across human societies. The research by doctoral student Irene Godoy (University of California, Los Angeles), under the supervision of Dr. Susan Perry, combines behavioral observation, genetics, and endocrinology to study mating behavior in the Lomas Barbudal population of wild capuchins in Costa Rica. These data will test the hypotheses that (a) early social familiarity, (b) phenotypic matching, or (c) the use of such cues as age proximity and adult male rank are the mechanisms by which individuals avoid mating with close relatives. Additional hypotheses regarding female versus male responsibility for behaviors that prevent inbreeding, and the importance of developmental aspects of co-socialization, also will be addressed.Observational data will be collected on the behavior of 24 adult females. Fecal samples will be collected non-invasively for later extraction of DNA or steroid hormones to determine paternity and maternity of individuals, and to track changes in female reproductive phase. Laboratory analyses will take place at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.Funding for this project will support training of research assistants and a multi-ethnic, first-generation Latina graduate student. Outreach presentations will be made at six local elementary schools in Costa Rica, promoting interest among the students in careers in science and encouraging conservation efforts to protect the highly endangered tropical dry forest environment.

白脸卷尾猴（Cebus capucinus）生活在由广泛的母系和父系亲属网络组成的社会群体中-这种人口统计学情况在哺乳动物中很少见，但强调了避免近亲繁殖的进化机制的重要性。研究这些灵长类动物是如何对某些个体而不是其他个体产生生殖厌恶的，将有助于我们更好地理解这些机制以及高度社会化动物中亲属识别的局限性。该项目还将提供比较工作，可能有助于了解人类社会避免乱伦的起源和变化。博士生Irene Godoy（加州大学，洛杉矶）在Susan佩里博士的指导下进行了这项研究，结合了行为观察，遗传学和内分泌学，研究了哥斯达黎加的Lomas Barbudal野生卷尾猴种群的交配行为。这些数据将检验以下假设：（a）早期社会熟悉度，（B）表型匹配，或（c）使用年龄接近和成年雄性等级等线索是个体避免与近亲交配的机制。关于女性与男性的行为，防止近亲繁殖的责任，以及共同社会化的发展方面的重要性，也将addressed.Observational数据将收集24个成年女性的行为的其他假设。将以非侵入性方式收集粪便样本，用于随后提取DNA或类固醇激素，以确定个体的父亲和母亲身份，并跟踪女性生殖阶段的变化。实验室分析将在德国莱比锡的马克斯·普朗克进化人类学研究所进行，该项目的资金将用于培训研究助理和一名多族裔的第一代拉丁裔研究生。将在哥斯达黎加的六所当地小学进行宣传介绍，提高学生对科学职业的兴趣，并鼓励保护工作，以保护高度濒危的热带干旱森林环境。
