Ancient Khoisan lineages survive in contemporary Bantu groups

An international team of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the CNRS in Lyon, France, have investigated the maternally inherited mitochondrial DNA of 500 individuals from southern Africa speaking different Khoisan and Bantu languages. Their results demonstrate that Khoisan foragers were genetically more diverse than previously known. Divergent mtDNA lineages from indigenous Khoisan groups were incorporated into the genepool of the immigrating Bantu-speaking agriculturalists through admixture, and have thus survived until the present day, although the Khoisan-speaking source populations themselves have become extinct.
