6958 - Lithic technology in the South-Central Andes: Continuity, change and units of analysis

The history of peopling in America is diverse and complex. In diferent spaces of the continent diferent cultural evolutionary trajetories occurred. Considering a more reduced scale, it is the case of the high lands of the South-Central Andes. This paper is focused in the Argentinian Puna, Salta Province (Northwest) and we analize the change in lithic technology along the Holocene. We taking into account the paleoenvironmental variations and cultural changes as the camelids domestication process. We think that in the frame of a subsistence strategy, lithic technology contributes for human adaptation. In those moments when a subsistence strategy is not succesfull for human adaptation, our expectative is a change in the strategy, and it would impact in lithic technology. It would be illustrated with our study case, where the increase of blade technology, change in raw materials selection and new artefactual classes development ocurred in the initial moments of intensification and domestication process (ca. 5000-3500 BP). The study case is compared with the regional archaeology with the aim of highlight the multiples evolutionary trajectories in the Argentinian Puna. Moreover, we discuss the units for the study of human cultural evolution taking into account traditional units as Paleondian-Archaic-Formative and other alternatives.
