Evaluating the Neolithic Expansion at Both Shores of the Mediterranean Sea.

摘要: During the Neolithic, human populations underwent cultural and technological developments that led to an agricultural revolution. Although population genetics evolution of European Neolithic have been extensively studied, little is known regarding expansion in North Africa with respect Europe. One could expect different environmental geological conditions at both shores Mediterranean Sea contrasting expansions. In order test this hypothesis, we compared Europe accounting for possible migration between them through Strait Gibraltar. We analyzed entire X chromosome 580 individuals from 20 spatially distributed along Next, applied approximate Bayesian computation based on extensive explicit computer simulations select among alternative scenarios Gibraltar estimate parameters Our results suggest that, despite being more technologically advanced, did not expand faster than Paleolithic populations, which be interpreted as a consequence sedentary lifestyle. detected reciprocal Iberian Peninsula Counterintuitively, found studied expansions presented similar levels carrying capacity migration, occurred comparable speeds, suggesting demic process substitution hunter-gatherer populations. Altogether, was so different, perhaps because these shared technical abilities lifestyle patterns.
