El poblamiento de la región central del territorio argentino durante la transición Pleistoceno-Holoceno (12.000 – 9.000 a.P.)

Abstract

The human dispersal in Southern South America during Pleistocene-Holocene Transition (12,000 – 9,000 BP), was focused from different theoretical approaches in the last years, trough both hemicontinental and regional studies. This paper presents archaeological evidences for the human occupation in central Argentina during the transition and its implications for the understanding of the exploration and colonization process. It is concluded that the first exploratory attempts in the central Argentina began at least 11,000 years B.P., but the people would not had been definitively settled until after 9,000 years B.P., as it is suggested by the low demographic density during the Pleistocene-Holocene transition. This situation would had difficulted colonizing the region in a definitive way, together with possible local population extinctions and failed colonizations.
