WebNational Center for Biotechnology Information WebIn the case of humans, the genetic diversity decreases essentially linearly with increasing geographic distance from Africa [2, 3], which is indicative of the human mi-gration out of Africa. It is hoped [9], that the observed patterns of neutral genetic diversity can be used to infer details of the corresponding colonization pathways.
