The complete genome sequences of an indigenous hunter-gatherer from Namibia’s Kalahari Desert and of a Bantu from southern Africa are presented in this week’s Nature. Alongside these genomes are presented the sequences of the protein-coding regions from three other hunter-gatherer groups from the Kalahari.
