Patagonian archaeology and the reconstruction of indigenous history

In this paper we review archaeological and anthropological traditional explanations of diversity formation and social homogeneity in Patagonia. In spite of «Archaeological Culture» concept, our goal is to look for alternatives based upon a different concept of what «ethnicity» is among hunter-gatherer societies. This new perspective considers the characteristic dynamics of the different possible social interaction processes, the aggregation/segregation mechanisms and the irregular and changing formation process of social norms. As methodology, we suggest distributed computational simulation that is the building of artificial societies.
