Baboon Rank and Paternity

草原狒狒代表了一组密切相关的种群 生活在撒哈拉以南非洲热带雨林之外。 科学家们不同意是否它们包括一个或几个 物种，因为虽然它们在形态上非常相似， 人口在社会特征上有很大差异。 为 灵长类社会组织及其关系分析 对人类来说，草原狒狒是极好的研究对象。 为了 为了了解这些人之间的社会关系， 一个人口，有必要知道谁是父母的 个别婴儿。 以前的研究受到了 只知道谁是每个婴儿的母亲。 以前对这一种群的长期实地观察， 主要研究者已经了解了所有个人 行为上 母性是已知的，但父权-基于 行为观察只是假设 在这项研究中，遗传 亲子鉴定也将确定谁是父亲 每个婴儿。 这些遗传学研究将检验这一假设 这种行为的父亲（根据观察， 动物）也是遗传学上的父亲。 作为这项研究的结果，将有可能测试各种 行为问题，如：是否近亲繁殖和乱伦 发生;父亲的确定性是否与保护有关， 以及，男性获得阿尔法地位是否与 他父亲的地位。

Savanna baboons represent a group of closely related populations living across subsaharan Africa outside the tropical rain forest. Scientists do not agree whether they comprise one or several species because, although they are very similar morphologically, populations differ significantly in social characteristics. For the analysis of primate social organization and its relationship to humans, savanna baboons are thus excellent subjects. In order to understand the social relationships among individuals in such a population, it is necessary to know who are the parents of individual infants. Previous studies have been hampered by knowing only who is the mother each infant. Previous long-term field observations of this population by the Principal Investigator have resulted in knowing all individuals behaviorally. Maternity is known, but paternity--based on behavioral observations--is only assumed. In this study genetic studies (paternity tests) will also determine who the father is of each infant. These genetic studies will test the hypothesis that such behavioral father (based on observations of the animals) is also the genetic father. As a result of this study it will be possible to test a variety of behavioral questions such as: whether inbreeding and incest occur; whether paternal certainty is related to protection from infanticide; and, whether male access to alpha status is related to the status of his father.
