This research project examines the evolutionary genetics of a group of New World primates. The goals of the study include a reconstruction of the ancient invasion of Central America by howler monkeys and, as a secondary objective, a genetic analysis of social structure in a well-studied population of mantled howlers. These objectives will be accomplished by comparing the genetic similarities between pairs of populations and pairs of individuals, respectively, using a DNA fingerprinting technology we developed specifically for these species. This study will significantly augment our understanding of primate evolution in two ways. First, we will provide a preliminary model for the population genetics of Central American primates in general, thus, providing a useful contrast with better known primate systems from Africa and Asia. Second, the information generated by this study about New World primate genetics will provide basic information that can lay the foundation for future ecological and evolutionary studies in this group.

这个研究项目检查了一组新世界灵长类动物的进化遗传学。 这项研究的目标包括重建吼猴对中美洲的古代入侵，作为次要目标，对一个经过充分研究的mantled howlers种群的社会结构进行遗传分析。 这些目标将通过使用我们专门为这些物种开发的DNA指纹技术分别比较成对种群和成对个体之间的遗传相似性来实现。 这项研究将从两个方面大大增加我们对灵长类进化的理解。 首先，我们将提供一个初步的中美洲灵长类动物的群体遗传学模型，从而提供一个有用的对比，更好地了解非洲和亚洲的灵长类动物系统。 其次，这项研究产生的关于新世界灵长类遗传学的信息将提供基本信息，为该群体未来的生态和进化研究奠定基础。
