Human demographic history: refining the recent African origin model

Curr Opin Genet Dev. 2002 Dec;12(6):675-82. doi: 10.1016/s0959-437x(02)00350-7.

Abstract

Recent studies of large portions of the human genome support a recent origin of modern humans from an African stock after a bottleneck of moderate size followed by a range expansion out of Africa. Under this simple scenario, patterns of molecular diversity suggest that balancing selection could be more prevalent than positive selection in coding regions.
