THE TEST OF COMPETING MODELS FOR THE PREHISTORIC PEOPLING OF THE AZAPA VALLEY, NORTHERN CHILE, USING MATRIX CORRELATIONS

This study reports biodistances from nonmetric dental traits for eleven mortuary samples -an Andean Paleoindian sample, a Tiwanaku sample, and nine from the Azapa Valley- to test three models for the prehistoric population dynamics of the Azapa Valley, Chile, using matrix correlation analysis of hyp...
