The primary objective of this project is to search for sites containing primate fossils from the middle Tertiary in South America. There has long been debate as to the path by which the higher primates appeared in the Old and New World. While there have been significant discoveries in the Old World, knowledge of early higher primate evolution in the Americas is scant. A principle question that remains to be answered is whether prosimian grade primates evolved into a monkey grade independently in the New and Old Worlds or whether this occurred once. In the latter case the last common ancestor of the two would have already have been monkey. The investigators have identified geological deposits in Bolivia which show promise of bearing fossils from this time period. With the assistance of the Bolivian Geological Survey they will search for fossils from this time period.

该项目的主要目标是在南美洲寻找含有中第三纪灵长类动物化石的遗址。关于高等灵长类动物是如何在旧世界和新世界出现的，人们一直争论不休。虽然在旧大陆有重大发现，但对美洲早期高等灵长类动物进化的了解却很少。一个仍待回答的主要问题是，原猿级灵长类动物是在新旧世界独立进化成猴级的，还是只发生过一次。在后一种情况下，两者最后的共同祖先可能已经是猴子了。调查人员已经确定了玻利维亚的地质沉积物，有望发现这一时期的化石。在玻利维亚地质调查局的协助下，他们将寻找这一时期的化石。
