Primeros poblamientos en el Cono Sur de America (XII-IX milenio aP)

A brief analysis of human occupation recorded in early Pleistocene and Holocene contexts in what are now Argentina and Chile. Sites are assessed which have been subjected to multidisciplinary, chronostratigraphic studies and which may represent certain differentiated patterns of adaptative behaviour in separate regions within the Southern Cone. Approximately 12 early Archaic and 17 Paleoindian sites meeting these criteria have been identified in the two countries dating up to the beginning of the 8th millenium BP. Our aim is to re-evaluate problems: specifically the principles of superposition and association, and understanding of the processes by which the archaeological record was formed and modified, strictly adhering to an experimental system of taphonomic and chronostratigraphic evaluations. In this way we hope to develop a database for investigating regional adaptive patterns of behaviour in relation to the distribution of biotic populations. -from English summary
