From Complex Hunter-gatherers in the Eastern Sahara to the Early Nile Neolithic Karin Kindermann & Heiko Riemer (University of Cologne, Institute of Prehistoric Archaeology, African Archaeology) ABSTRACT The beginning of food production in the Nile Valley appears as a highly complex and multicausal phenomenon, coinciding with a number of fundamental environmental and cultural changes. In all its facets, it can only be interpreted as a long-term, episodic process with various protagonists, and changing conditions for cultural contact and exchange. This together with the deficient archaeological data have yet hampered tracing even the basic lines and modes how, where, and when the Neolithic developed. As viewed from the Saharan ecozone, especially from the Western Desert, two phenomena appear as of importance: Firstly, earliest domesticated animals occur in low percentages in Saharan hunter-gatherer communities, at latest from 6000 calBC onwards, predating the earliest Neolithic at the Nile. It appears that this development goes along with a trend towards cultural complexity in hunter-gatherers showing a shift towards pottery production, more residential campsites, intensified plant exploitation, and the like. Secondly, in tandem with the beginning climatic trend towards aridity from the late 6th millennium onwards, Saharan core areas were abandoned and people retreated to more favored landscapes, such as the oases and the Nile Valley. Seasonal contacts between the oases and the Nile Valley are already evident for the periods predating the onset of dryer condition. Yet the almost identical lithic material of the Fayum Neolithic with the preceding sites in the oases and the limestone plateau signals that communities from the desert began to concentrate and settle down in the Fayum and possibly in other locations along the Nile.
