WebAbstract. Multiregional evolution is a model to account for the pattern of human evolution in the Pleistocene. The underlying hypothesis is that a worldwide network of genic exchanges, between evolving human populations that continually divide and reticulate, provides a frame of population interconnections that allows both species-wide ...

WebJul 18, 2007 · The multiregional hypothesis holds that modern humans emerged from populations of "archaic" hominids in Africa, Europe, and Asia that evolved locally but also exchanged genes.
