Prehistory, with the assistance of physical anthropology, palaeogenetics and environmental sciences, aims to explain the processes through which continents were peopled.

There is no direct, constant relationship between the anthropological and cultural aspects of modernity. Anthropologically modern peoples display a certain heterogeneity that is not unconnected with earlier peoples, and the culture produced by modern humans, which is also heterogeneous, is differentiated diachronically and according to territory. Though paleogenetic research seems to point us to a single, African source for modern peoples, who had replaced the pre-sapiens populations in Eurasia, this view is not completely proven or accepted. On the other hand, (...) paleo-genetic research has contributed to our relinquishing the hypothesis of a multiregional ‘total continuity’ of local pre-modern populations in the Old World. Indeed the theory of a partial replacement, by a migration ‘out of Africa’, appears to be getting increasingly plausible. This article deals with the problems of the origins of modern man from the points of view of anthropological, paleogenetic, paleoenvironmental and cultural approaches. (shrink)
