the first settlers of Patagonia and several extinct species: Hemiauchenia cf. paradoxa, Lama gracilis, Panthera onca mesembrina, Hippidion saldiasi, Megatherium americanum cf. and Arctotheirum sp. Present fauna such as Lama guanicoe, Rhea sp., Lycalopex griseus and Lycalopex sp. is also contemporary. All the information points to the fact that southern Patagonia had paleoenvironmental diversity, plurality of sites and different use patterns of wildlife during the Pleistocene-Holocene transition. The use and consumption of the three species of camelids and the survival of Hippidion saldiasi in specific environments of the plateau is also highlighted. These issues are discussed taking into account available information relating to the early human occupation of the Southern Cone, as part of a growing methodological improvement that seeks to integrate different research avenues.
In this work we uncovered a well-supported pattern of the demographic change in the populations from South-Central Andes and Patagonia, obtained on the basis of different data and quantitative approaches, which suggests that the incorporation of domestic resources was paramount for the demographic expansion of these populations during the Holocene.
Este trabajo busca generar un aporte al conocimiento de la dinámica poblacional de cazadores, en Patagonia meridional, durante el Holoceno medio y tardío en el marco de condiciones climáticas altamente fluctuantes. Para este fin se analizaron distintas líneas de evidencias arqueológicas provenientes de diferentes ambientes del centro-oeste de la provincia de Santa Cruz, Argentina. Se identificó una interesante variabilidad del registro arqueológico, en estrecha relación con las modificaciones ambientales registradas en el Holoceno.Palabras claves: Patagonia, cazadores-recolectores, Holoceno.this article seeks to generate a contribution to the knowledge of the peopling dynamics of hunters in southern Patagonia during the middle and late holocene within fluctuating climatic conditions. in order to do this, different archaeological evidences were analyzed from diverse environments in Santa cruz province (Argentina). An interesting variability in the archaeological record was identified, in close relation with the environmental modifications registered in the holocene.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
