Phylogenetic Study of South American Monkeys

本研究的目的有两个：首先利用形态学方法，对现存的南美洲猴，特别是已发现直接古化石的Alouatta、Saimiri、Cebus和Aotus的分类关系进行了初步的研究，二是通过对中新世灵长类的古生物发掘，为南美洲猴的生殖发育提供基础资料，通过地质学方法收集中新世灵长类动物生存的绝对年龄和古环境的基本信息，在哥伦比亚乌伊拉省半荒漠地区进行古生物学和地质学研究，该地区自1979年以来已发现灵长类动物化石。生活南美猴子的比较研究将在巴西的几个博物馆进行，如里约热内卢灵长类动物中心，贝伦和马瑙斯自然历史博物馆。在阿根廷、巴西、玻利维亚和美国的几所大学和研究机构将进行化石和活的南美猴子之间的比较研究。

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, Cebus and Aotus 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 and institutions in Argentina, Brasil, Bolivia and USA.
