Although it is widely accepted that modern humans (Homo sapiens sapiens) can trace their African origins to 150-200 kilo years ago (kya) (recent African origin model; Henn et al, 2012; Ingman et al, 2000; Poznik et al, 2013; Weaver, 2012), an alternative model suggests that the diverse populations of our species evolved separately on different continents from archaic human forms (multiregional ...

A synthetic analysis of molecular, fossil and biogeographical data gives a remarkably consistent scenario for the evolution of the catarrhine primates - the hominoids and Old World monkeys. This analysis supports the African location of the common ancestor of the Old World monkeys, and suggests that the Asian colobine monkeys and macaques dispersed out of Africa into Eurasia within the past ten...

From northeastern Eurasia to the Americas, a three-stage spread of modern humans is considered through large-scale intermittence (exploitation/relocation). Conceptually, this work supports intermittence as a real strategy for colonization of new habitats. For the first stage, northeastern Eurasia travel, we adapt our model to archaeological dates determining the diffusion coefficient (exploitat...
