Hunter-gatherer environments at the Late Pleistocene sites of Mwanganda's Villa...
Schilt, Flora; Miller, Christopher E.; Wright, David K.; Mentzer, Susan M.; Mercader, Julio; Moss, Patrick; Choi, Jeong-Heon; Siljedal, GunnarMwanganda's Village (MGD) and Bruce (BRU) are two open-air site complexes in northern Malawi with deposits dating to between 15 and 58 thousand years ago (ka) and containing Middle Stone Age (MSA) lithic assemblages. The sites have been known since 1966 and 1965, respectively, but lacked chronometric and site formation data necessary for their interpretation. The area hosts a rich stone artifact record, eroding...
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...
