Abstract<\/h4>\n

Sub-equatorial Africa is today inhabited predominantly by Bantu-speaking groups of Western African descent, whose ancestors, in many cases, replaced, displaced, or assimilated local hunter-gatherer groups.<\/p>\n

In eastern Zambia, there is evidence of Bantu-speaking agriculturalists from circa 2000 years ago. Little is known about the genetic affinities of the hunter-gatherers who inhabited the area before that.<\/p>\n

Gwenna Breton will present a study focusing on two isolated communities in Zambia, known as BaTwa and possible descendants of recent hunter-gatherers. By analysing modern DNA from these populations, the researchers have identified a hunter-gatherer-like genetic ancestry in the BaTwa. They propose a model of the BaTwa population history and discuss how it compares with the archaeological evidence.<\/p>\n

The results were discussed with the study participants prior to publication, and Gwenna will present some aspects of the presentation trip.<\/p>\n
