Ancient DNA and deep population structure in sub-Saharan African foragers
Lipson, Mark; Sawchuk, Elizabeth A.; Thompson, Jessica C.; Oppenheimer, Jonas; Tryon, Christian A.; Ranhorn, Kathryn L.; de Luna, Kathryn M.Multiple lines of genetic and archaeological evidence suggest that there were major demographic changes in the terminal Late Pleistocene epoch and early Holocene epoch of sub-Saharan Africa(1-4). Inferences about this period are challenging to make because demographic shifts in the past 5,000 years have obscured the structures of more ancient populations(3,5). Here we present genome-wide ancient DNA data for si...
Early human impacts and ecosystem reorganization in southern-central Africa
Thompson, Jessica C.; Wright, David K.; Ivory, Sarah J.; Choi, Jeong-Heon; Nightingale, Sheila; Mackay, Alex; Schilt, Flora; Otárola-Castillo, ErikModern Homo sapiens engage in substantial ecosystem modification, but it is difficult to detect the origins or early consequences of these behaviors. Archaeological, geochronological, geomorphological, and paleoenvironmental data from northern Malawi document a changing relationship between forager presence, ecosystem organization, and alluvial fan formation in the Late Pleistocene. Dense concentrations of Midd...
