Hunter–gatherer dispersals in the mammoth-steppe: technological provisioning and land-use in the Enisei River valley, south-central Siberia

Late Pleistocene Siberia was characterized by a unique mammoth-steppe biome. Two prevailing hypotheses exist to explain modern human dispersals in the Siberian mammoth-steppe. Upper Paleolithic human populations were either maintained continuously throughout the late Pleistocene or the peopling of this region resulted from multiple dispersal events. Past attempts at explaining the colonization process have resulted in culture-historical interpretations. This article uses lithic technological data from middle and late Upper Paleolithic sites in the Enisei River valley of south-central Siberia to explain human dispersals from a behavioral perspective. Technological provisioning and land-use strategies are reconstructed to help explain dispersal processes. Results of the study demonstrate that hunter–gatherers were using different adaptive strategies before and after the Last Glacial Maximum, indicating that multiple dispersal events shaped the peopling of Siberia.
