Populations of Homo erectus may have survived into the late Pleistocene of Java (50,000 years ago), possibly coexisting with modern humans (H. sapiens) in both time and space. Such survival of H. erectus would parallel the coexistence of Neandertals and modern humans in Europe and also begs the question of why only modern humans remain in both regions today. This project tests whether such late-surviving populations of H. erectus existed in Indonesia through a two-year field program in the Solo River Valley, Java. The team will undertake new excavations, microstratigraphic work, and systematic faunal and taphonomic analyses of recovered remains at known sites in the 20 meter terrace (e.g. Jigar, Ngandong) and identify other sites in a similar geological context for test excavation. The team will also test the accuracy of the previously acquired radiometric age estimates (U-series/ESR ages) using other techniques (including radiocarbon (14C), closed system U-series, luminescence and cosmogenic radionuclide techniques). This is the first project to focus explicitly on questions of assemblage formation in Indonesia. These data, in conjunction with those developed for African and Eurasian localities, are critical pieces to modeling the evolution and dispersal of H. erectus.This project establishes a long term collaborative research and training program between Indonesian and American scholars dedicated to answering scientific questions and to the development of Indonesian scientific opportunities. The program is designed to include training opportunities for Indonesian and American students and infrastructure for Indonesian scientists and collections. Field and laboratory training opportunities and at least two PhD projects will be provided for Indonesian graduate students in addition to practical training in curation of systematic collections, taphonomic analyses, and geological field and excavation techniques. International field training will be provided for at least two American graduate students. The program is likewise designed to foster relationships between Indonesian and American graduate students with the goal of encouraging the creation of additional productive collaborations, such as the one between the PI and her Indonesian counterpart. The U.S. graduate students are female, the project thus provides field opportunities in areas (field geology and field paleoanthropology) in which women have been traditionally underrepresented. The project also supports laboratory training of at least one American undergraduate. Scientific research will be supported by augmenting the laboratory collections of Gadjah Mada University with additional computer equipment for field and lab archiving and by assisting in systematic curation efforts. Infrastructure, including curatorial equipment, are provided to ensure an appropriate environment for long term study.

HOMO直立的人群可能已经幸免于Java的晚更新世（50，000年前），可能在时空和空间中与现代人类（H. Sapiens）共存。 直立烟草的这种生存将与欧洲尼安德特人和现代人类共存，并引出一个问题，即为什么当今两个地区只有现代人类。 该项目测试了印度尼西亚通过在Java的Solo River Valley的两年野外计划中是否存在这样的晚期直立人群。 该团队将在20米露台的已知地点（例如Jigar，ngandong）的已知地点进行新的发掘，微地层工作以及系统的动物和taphonal分析，并在类似的地质环境中识别出其他地质的地点。 该团队还将使用其他技术（包括放射性碳（14C），封闭的系统U系列，发光和宇宙性放射性核素技术）来测试先前获得的放射年龄估计（U系列/ESR年龄）的准确性。 这是第一个明确关注印度尼西亚组合形成问题的项目。 这些数据以及针对非洲和欧亚地区开发的数据，是建模直立螺旋体的演变和分散的关键部分。该项目建立了一个长期的协作研究和培训计划，致力于回答科学问题和科学问题和科学问题和美国学者之间开发印尼科学机会。 该计划旨在为印尼和美国学生提供培训机会以及印尼科学家和收藏的基础设施。 除了在系统收集，Taphonomic分析以及地质领域和挖掘技术方面，还将为印尼研究生提供现场和实验室培训机会以及至少两个博士学位项目。 至少有两名美国研究生将提供国际现场培训。 该计划同样旨在促进印尼和美国研究生之间的关系，目的是鼓励建立其他生产性合作，例如PI和她的印尼同行之间的关系。 美国的研究生是女性，因此该项目在传统上人数不足的领域（现场地质学和古人类学）方面提供了现场机会。 该项目还支持至少一名美国本科生的实验室培训。 科学研究将通过通过增加现场和实验室档案的其他计算机设备以及协助进行系统的策划工作来增强Gadjah Mada University的实验室收集来支持科学研究。 提供了包括策展设备在内的基础设施，以确保适当的长期研究环境。
