Late Pleistocene Demography and the Appearance of Modern Human Behavior -- Powell et al. 324 (5932): 1298 -- Science
The origins of modern human behavior are marked by increased symbolic and technological complexity in the archaeological record. In western Eurasia this transition, the Upper Paleolithic, occurred about 45,000 years ago, but many of its features appear transiently in southern Africa about 45,000 years earlier. We show that demography is a major determinant in the maintenance of cultural complexity and that variation in regional subpopulation density and/or migratory activity results in spatial structuring of cultural skill accumulation. Genetic estimates of regional population size over time show that densities in early Upper Paleolithic Europe were similar to those in sub-Saharan Africa when modern behavior first appeared. Demographic factors can thus explain geographic variation in the timing of the first appearance of modern behavior without invoking increased cognitive capacity.

On the Human
On the Human (OTH) is a community of university professors who teach courses on humans and their relations to animals and machines. We are fascinated by human singularity: the properties, if any, that distinguish persons from other biological creatures and artificial intelligences. We are also interested at OTH in the ethical implications of these properties.
