The African early Middle Pleistocene saw the emergence of archaic Homo, the expansion of hominin brain capacities to near-modern dimensions, and the first appearance of a battery of sophisticated new technologies. And yet, as relatively few African localities sample this important timeframe (i.e. the period from c.781–500ka), the specific details regarding the timing, setting, and dynamics that underlie the emergence and early evolution of these advances remain poorly understood. With an estimated minimum age of c.600-500ka, recent paleoanthropological discoveries at the open-air site of Farre, located in the Chalbi Basin of northern Kenya, add important new data relevant to these issues
With National Science Foundation support, Drs. J. Ferraro, G. Stinchcomb, K. Binetti, K. Uno, and a large interdisciplinary team of collaborators will conduct a multi-year investigation of the Farre locality and its contents. Fossils and artifacts, numbering in the thousands, are found blanketed across the top of a low hill. A small test excavation has yielded several hundred finds in situ, and a rich target-layer of fossils and artifacts (and presumed source of the surface materials) can be seen eroding from an adjacent erosional slope. Finds include artifacts consistent with both Early and Middle Stone Age technologies, coupled with fossil taxa indicating an age in excess of 500ka. The team will refine the stratigraphy and geochronology of the site, allowing researchers to accurately place inferred hominin adaptations within local, regional, and global paleoenvironmental contexts. Archaeological analyses will refine our understanding of the emergence and early evolution of important technological capacities (including the production of stone points and the appearance of Levallois flake-based reduction techniques) as well as to help elucidate the content and context of hominin dietary and foraging adaptations. Collectively, these studies will improve our understanding of archaic Homo paleobiology in sub-Saharan Africa, a topic of considerable interest and importance, but for which we currently possess very little data.
In addition, discoveries at Farre are unique in the region, and extend the c.4.1ma to c.750ka record represented in the nearby Turkana Basin by up to c300ka. Farre may thus help bridge a long-standing gap in the record of this paleoanthropologically-important region, and add increased time-depth to regional time-series analyses of biotic responses to climate change. In a similar vein, discoveries at Farre meet a recent request from the National Research Council to discover and investigate new hominin localities in Africa with which we can address issues of hominin-environment interactions and the emergence of key anatomical, technological and sociocultural adaptations.
