Under the supervision of Dr. Sally McBrearty, Cara Roure will excavate three Middle Pleistocene archaeological sites in the Kapthurin Formation, Kenya, in order to document land use patterns and subsistence behavior of Middle Pleistocene hominids, specifically H. rhodesiensis. The Kapthurin Formation, west of Lake Baringo in the Kenya Rift Valley, consists of a succession of artifact- and fossil-rich sedimentary members that span most of the Middle Pleistocene. The formation contains many documented archaeological and fossil localities, some of which have yielded fossil remains of H. rhodesiensis, considered the direct precursor to modern H. sapiens. This project focuses on the interval associated with the hominid fossils, from 543 to ka. Detailed paleoenvironmental reconstruction of the basin during this interval has identified a range of contemporaneous microhabitats around a saline lake, a fresh water spring and a riverine system. A site from each of these environmental types will be excavated to supply a sample of behavior across varied habitats. GIS will provide an integrated format within which archaeological data can be related to environmental and spatial variability to create a model of ranging and land use patterns for H. rhodesiensis. Patterns identified in the data will then be compared to those documented for Early Pleistocene hominids and modern foragers in Africa.This project has multiple levels of significance for archaeology and evolutionary anthropology. The understanding of the origins of modern H. sapiens' behavioral adaptation is of key importance. This adaptation is most easily recognized as the evolution of the cognitive capacity for symbolic behavior. A current debate now focuses on the origins of such behavior. A long held view is that this capacity appeared suddenly and late as a "behavioral revolution," long after the origin of anatomically modern H. sapiens. Challenging this, a new hypothesis poses that the modern behavioral adaptation arose gradually but much earlier, in the Middle Pleistocene of Africa. This project is unique in its documentation of land use patterns of African later Middle Pleistocene hominids and will contribute to understanding of origin and evolution of our species. The results will be directly applicable to the ongoing debate regarding the origins of behavioral adaptation of modern H. sapiens in the African Middle Pleistocene.The interdisciplinary nature of this research emphasizes the need for collaboration between many specialties including geology, archaeology, paleontology, GIS, and museum studies. Roure's project is being run in close collaboration with the National Museums of Kenya and will employ museum staff. Roure will be providing field training for Kenyan excavators, and two junior graduate students from the University of Connecticut. Outreach includes working with students at Rectory School (USA) and Loberer Primary School, located in the study area to better understand prehistory and evolution (through classes and textbooks). Results of this project will be applicable to dissemination in academic journals over several disciplines including archaeology, evolutionary anthropology, and geology. However, this work will also impact both undergraduate and secondary education as there is an intense interest in the origins of our species.

在Sally McBrearty博士的监督下，Cara Roure将在肯尼亚Kapthurin地层中挖掘三个中更新世考古遗址，以记录土地使用模式和中更新世原始人的生存行为，特别是H。罗得西亚人卡普图林组位于肯尼亚裂谷巴林戈湖以西，由一系列人工制品和化石丰富的沉积物组成，跨越了中更新世的大部分时间。该地层包含许多有文献记载的考古和化石地点，其中一些已经产生了H。rhodesiensis被认为是现代H.智人该项目的重点是与人类化石有关的时间段，从543年到ka。详细的古环境重建的盆地在此期间确定了一系列的同期微生境周围的盐湖，淡水泉和河流系统。每一种环境类型的遗址都将被挖掘出来，以提供不同栖息地的行为样本。地理信息系统将提供一个综合的格式，其中考古数据可以与环境和空间变化，以创建一个模型的范围和土地利用模式的H。罗得西亚人然后将数据中识别的模式与非洲早更新世原始人和现代觅食者的记录进行比较。该项目对考古学和进化人类学具有多层次的意义。对现代H.智人的行为适应至关重要。这种适应最容易被认为是符号行为认知能力的进化。目前的争论集中在这种行为的起源上。一个长期持有的观点是，这种能力是作为一种“行为革命”突然出现的，而且出现得很晚，比解剖学上现代的H。智人与此同时，一个新的假说提出，现代行为适应逐渐出现，但更早，在中更新世的非洲。该项目在记录非洲中更新世晚期原始人的土地利用模式方面是独一无二的，将有助于了解我们物种的起源和进化。研究结果将直接适用于正在进行的关于现代人类行为适应起源的争论。这项研究的跨学科性质强调了许多专业之间合作的必要性，包括地质学，考古学，古生物学，GIS和博物馆研究。鲁尔的项目正在与肯尼亚国家博物馆密切合作，并将雇用博物馆工作人员。Roure将为肯尼亚挖掘机和康涅狄格大学的两名大三研究生提供实地培训。外联包括与位于研究区的Rectory学校（美国）和Loberer小学的学生合作，以更好地了解史前史和进化（通过课程和教科书）。该项目的成果将适用于在学术期刊上传播，包括考古学，进化人类学和地质学。然而，这项工作也将影响本科和中学教育，因为人们对我们物种的起源非常感兴趣。
