Phylogenetic Study of South American Monkeys

本研究的目的有两个方面：一是通过形态学方法获得南美现存猴，特别是已发现直接古生物化石的Alouatta、Saimiri、Callithrix和Cacajao种的分类关系的基础资料；二是通过对中新世灵长类的古生物发掘，获得南美猴系统发育的基础资料，并用地质学方法收集中新世灵长类栖息的绝对年龄和古环境的基本信息。将在哥伦比亚惠拉省的半荒漠地区进行古生物和地质研究。对南美现存猴子的比较研究将在巴西的几个博物馆进行，如里约热内卢的灵长类中心、贝伦和马瑙斯的自然历史博物馆。化石和活着的南美猴子的比较研究将在美国的几所大学进行，例如加州大学伯克利分校和杜克大学。

The purpose of the present research is two-fold : First to get the basic data for the taxonomic relationships among the living South American Monkeys, especially Alouatta, Saimiri, Callithrix and Cacajao of which the direct ancient fossils were already discovered, by means of morphological methods, and second to get basic data for the phylogeny of the South American Monkeys by means of paleontological excavation of the Miocene primates and to gather the basic information about the absolute age and paleo-environment of which Miocene primates inhabited by means of geological methods.The paleontological and geological researches will be done in the semidesert area in the Huila Department of Colombia, where we have already discovered fossil primates since 1979. The Comparative studies of living South American monkeys will be done in the several museums in Brasil, such as Primate Center of Rio de Janeiro, Natural History Museums of Beren and Manaus. The comparative studies between fossil and living South American monkeys will be done in the several universities in USA,for example, in University of Callifornia at Berkeley and Duke University.
