Abstract

A central issue in paleoanthropology is whether modern humans emerged in a single geographic area and subsequently replaced the preexisting people in other areas. Although the study of human mitochondrial DNAs supported this single‐origin and complete‐replacement model, a recent paper1 argues that humans expanded out of Africa more than once and regionally interbred. However, both the genetic antiquity and the impact of the African contribution to modern Homo sapiens are so great as to view Africa as a central place of human evolution. Despite the possibility that out‐of‐Africa H. sapiens interbred with other populations, this evidence is more consistent with the uniregional hypothesis than the multiregional hypothesis of modern human origins.

The authors wish to correct a mistake which occurred in the reporting of one of the mutations. The mutation reported as 683insT is actually an insertion G mutation, and should thus be called 683insG.
