Why hunter-gatherer populations do not show signs of pleistocene demographic expansions.

Proceedings of the National Academy of Sciences of the United States of America - 14 Sept 1999

Excoffier L, Schneider S

Abstract excerpt

The mitochondrial DNA diversity of 62 human population samples was examined for potential signals of population expansions. Stepwise expansion times were estimated by taking into account heterogeneity of mutation rates among sites. Assuming an mtDNA divergence rate of 33% per million years, most populations show signals of Pleistocene expansions at around 70,000 years (70 KY) ago in Africa and Asia, 55 KY ago in...
