The Archaic Period in the south-central Andes

Although the Archaic Period of the south-central Andes is not well-known beyond Latin America, there is much of interest in it to archaeologists working with foraging populations. Like the North American Archaic and European Mesolithic, the Archaic in the region is characterized by ethnic differentiation, changes in the scale and frequency of residential mobility, resource intensification and specialization, and population growth. The origin and evolutionary trajectory of these trends are discussed within the context of the development of ecological complementarity, a strategy of land use that exploits the vertically stratified distribution of resources in the Andean environment.
