Climate changes, human peopling and regional differentiation during late Holocene in Patagonia

摘要: The main aim of this paper is to evaluate if certain processes that were documented in a specific area Central-Southern Patagonia during the Late Holocene also registered broader spatial scale. Previous investigations carried out our study located Central-Western Santa Cruz province, Patagonia, have stated climatic fluctuations (last 2500 years) cause reduction hunter-gatherers’ residential mobility. new conditions characterized by important environmental droughts, which increased Mediaeval Climatic Anomaly, circa 900 years BP. This mobility resulted concentrations populations low altitude basins and logistical seasonal mobility, defined as process extensification. In we take broad perspective what extent identified research had correlation larger regional Also assess lead differentiation among hunter-gatherer populations, previous European contact (450 BP). order achieve these aims, undertake coarse grain analysis, using available data published on composition distribution archaeological record for an about 450.000 km 2 . Specifically, consider evidence technology, zooarchaeology, rock art, mortuary paleodietary studies. analysis indicates reduced could occurred areas region, linked aforementioned changes. On issue differentiation, highlights complexity process. There are variety arguments both against idea regionalization Holocene.
