Animal husbandry in southern negroids: 700 AD. This article presents a study of the genomes of nine individuals from Southern Africa that allows us to reconstruct the demographic trajectories of the San people and their ancestors over the last 10,000 years. It is shown that South Africa was characterized by long-term genetic continuity from the early Holocene to the end of the Stone Age. Despite pastoral and agricultural influences, some San still retain an ancient Pleistocene genetic signature.
