A scenario of human dispersal in the northwestern Mediterranean throughout the Early to Middle Pleistocene

摘要: Abstract Throughout the Early to Middle Pleistocene several origination and extinction bioevents led a progressive rebuilding of structure Mediterranean mammalian communities. Understanding whether faunal dispersal turnovers developed on backdrop climatic changes or intrinsic biotic factors exerted more important control, it is an outstanding interest in elucidating ecological scenario, enabling humans disperse towards across region. Although link between human climate change possibly exists, many archaeologists continue reject environmental determinism. The first some groups was undoubtedly part renewal triggered by changes, but increase suitable prey limited competition with other predators would have been beneficial peopling. To contribute debate, fossil record large mammals has analysed aim delineating main biological events processes which affected evolution complexes, turn throughout results this study confirm that most renewals fauna (due both originations/dispersals extinctions) are connected major global that, via migrations events, altered palaeocommunity equilibrium, leading new intra- inter-guild dynamics. Changes richness crop biomass principal prey, as relative abundance forest open environment dwellers, had role opening favourable windows during late Pleistocene. Nonetheless, significant peopling occurred only after transition at time functional beginning
