Sitwe 23, a Complex ESA/MSA Locality in the Northern Luangwa Valley, Zambia
Bisson, Michael S.; Burke, Ariane; Schilt, Flora; Aleman, Julie; Peros, Matthew C.; Drapeau, Michelle; Katongo, Maggie; Kayuni, Martha NchimunyaThis paper describes the lithic aggregates from Sitwe 23 (SW23), a Stone Age locality in a previously unstudied region of the northern Luangwa Valley, Zambia. This area yielded two surface lithic scatters containing abundant artifacts derived from Pleistocene sediments on uplifted terrain and exposed by recent erosion on two adjacent terraces. The scatters are time-averaged palimpsests formed by deflation, but ...
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...
