TECNOLOGíA LíTICA Y ESTRATEGIAS DE SUBSISTENCIA DURANTE LOS PERíODOS ARCAICO Y FORMATIVO EN EL ALTIPLANO CENTRAL, BOLIVIA

changes in subsistence systems from hunter-gathering to plant cultivation and animal husbandry are one of the least understood aspects in the archaeology of the andean highlands. in this report we present preliminary results the analysis of settlement patterns and lithic materials recovered from the iroco area, in the northeast margin of lake uru-uru, in the central highlands of bolivia. changes in settlement systems between the archaic period (10,000-3,500 bp) and the formative period (3,500-1,600 bp) are related to changes in economic organization and mobility patterns. however, technological change is framed in a possible tradition of resource utilization and manufacturing processes applied to stone materials.
