The period from 4.5 to 3.5 million years ago is an important part of our evolutionary history, during which a number of hominin species appeared and diversified. In this project, the investigators will collect paleontological, archeological, and geological data from the Galili Formation in the Afar region of Ethiopia, which is known from initial surveys to include fossils for a range of species, including some hominin specimens. Additional findings at this location will contribute to the study of important issues in hominin evolution and adaptation, such as behavioral changes, expanded habitats, stone tool use, and regular meat eating. This project will provide training opportunities for graduate and undergraduate students and field personnel, and build paleontological and archeological research collections from a scientifically interesting period and region. Fossils and archeological materials, with information on their context, will be permanently curated at the Ethiopian National Museum, and data from geochronological and isotopic analyses will be added to relevant publicly-accessible databases. In this two-year field investigation of the Early Pliocene-Early Pleistocene Galili Formation, the investigators will expand on a previously NSF-funded survey of the project area; collect, prepare, and curate taxonomically, biochronologically, biogeographically, and paleoenvironmentally sensitive fossils; identify, sample, and process geological samples for dating; and develop a high-resolution geologic map and stratigraphy of the area. These project activities will improve the chronological control of the deposits, better document the time-successive diversity in fauna and environments, reconstruct basin geometry and evolution, and allow biological and geological comparisons with other Awash basin areas. Findings from this project will contribute to topics such as the transition to bipedality, the origins of stone tool manufacture and meat-eating, and the origins of the genus Homo. The Galili deposits are sampling a unique part of the ancient landscape, and comparisons with other similarly aged fossils from the Afar region, such as those from Woranso-Mille, Dikika, Hadar, and Middle Awash, will provide a more comprehensive understanding of the entire ancient Awash Basin to better understand that circumstances of early hominin evolution.

4.5到350万年前的时期是我们进化史的重要组成部分，在此期间，许多人类物种出现和多样化。在该项目中，研究人员将从埃塞俄比亚远处的Galili组收集古生物学，考古和地质数据，这是从初步调查中知道的，以包括一系列物种的化石，包括一些人类标本。该位置的其他发现将有助于研究人类进化和适应的重要问题，例如行为改变，扩大的栖息地，石材工具使用和定期肉类饮食。该项目将为研究生和本科生以及现场人员提供培训机会，并从科学有趣的时期和地区建立古生物学和考古研究收藏。埃塞俄比亚国家博物馆将永久策划化石和考古材料，并将其策划在埃塞俄比亚国家博物馆中，并将添加到相关的公开访问数据库中。 在对早期上新世至更新世的盖利利形成为期两年的现场调查中，研究人员将对先前由NSF资助的项目区域进行扩展；从分类，生物学，生物地理和古环境敏感的化石上收集，准备和策划。识别，采样和处理约会的地质样本；并开发该地区的高分辨率地质图和地层。这些项目活动将改善沉积物的时间顺序控制，更好地记录动物和环境中时间成功的多样性，重建盆地几何和进化，并允许与其他Awash盆地地区进行生物学和地质的比较。该项目的发现将有助于主题，例如过渡到双皮亚，石材工具制造和食肉的起源以及Homo属的起源。 Galili沉积物是对古代景观的独特部分进行取样，并与其他类似老化的化石进行了比较，例如来自Woranso-Mille，Dikika，dikika，hadar和Middle Awash的化石，将对整个古老的Awash盆地提供更全面的了解，以更好地了解早期的Hominin Evolution早期进化情况。
