Dental morphology in a prehistoric sample of araucanos from patagonia and his biological relationship with other prehistoric populations from Argentina and the world

The prevalence of 25 dental traits in a simple of pre-hispanic mature skulls belonging to Museo de La Plata (Agentina) were analyzed. Both arches, upper and lower, and all of the permanent dentition with the exception of the third molars were studied. The main objective of this study was to establish the morphological dental pattern according to absolute and relative frequency of the traits that characterize the dentitions of araucanos. It can be concluded, from the frecuency of the traits analyzed, that the sample presents similarities with momgoloid synodonts and it moves away from the European and African populations.
