The primary objective of this proposal is to continue excavations in Tugen Hills, west of Lake Baringo, Kenya. This region contains an excellent series of fossiliferous geological strata dating to the period of 16 to approximately 1.5 million years ago; a time of major significance in the evolution of the higher primates and bracketing the time of appearance of the first hominids or human ancestors. The project has already discovered new primate specimens as well as remains of other mammalian fossils. In total, these specimens are elucidating not only the anatomical details of the development of various higher primates, but also setting them within an environmental context, thus clarifying the conditions which molded the species' evolution. Further fossiliferous sites will be identified while currently known sites will continue to be excavated.

该提案的主要目标是继续在肯尼亚巴林戈湖以西的图根山进行挖掘。 该地区包含一系列优良的含化石地质地层，其历史可追溯到 16 至约 150 万年前；对高等灵长类动物的进化具有重要意义的时期，也是最早的原始人类或人类祖先出现的时期。 该项目已经发现了新的灵长类动物标本以及其他哺乳动物化石的遗骸。 总的来说，这些标本不仅阐明了各种高等灵长类动物发育的解剖学细节，而且将它们置于环境背景下，从而阐明了塑造该物种进化的条件。 将确定更多化石遗址，同时将继续挖掘目前已知的遗址。
