Kinver, M., Early Humans Began in Southern Africa, Study Suggests, BBC, Mar 2011
Modern humans may have originated from southern Africa, an extensive genetic study has suggested.
Data showed that hunter-gatherer populations in the region had the greatest degree of genetic diversity, which is an indicator of longevity.
It says that the region was probably the best location for the origin of modern humans, challenging the view that we came from eastern Africa.
The study appears in the Proceedings of the National Academy of Sciences.
