Abstract | Current linguistic and ethnohistoric models propose that the Aymara ethnic group were late migrants into the Titicaca basin, and favor Uru or Pukina ethnic groups as the authors of the Tiwanaku civilization, which dominated the Central Andes for roughly half a millenium (AD500-1000). A review of linguistic, ethnohistoric, and archaeological data suggests that the Aymara may have been organized in a manner termed 'salpicada', which resulted in the historic pattern of intermingled Uru, Pukina and Aymara communities. |
