COBOS, Virginia A; DELLA NEGRA, Claudia  and  BERNAL, Valeria. Patrones de variación morfométrica craneofacial en poblaciones humanas del noroeste de patagonia durante el holoceno tardío. Rev Arg Antrop Biol [online]. 2012, vol.14, n.1, pp.5-6. ISSN 1514-7991.

The morphological variation of human populations that inhabited the actual territory of the Neuquén province during the Late Holocene, constitutes an area of research scarcely explored to date. Consequently, the present work aims at quantifying the pattern of variation and the degree of disparity in facial shape and size of the human populations from northwestern Patagonia during the late Holocene. For comparative purposes, we analyzed two samples from northeastern (Río Negro) and Center East (Chubut) Patagonia. These are two areas for which detailed archaeological and bioarchaeological information is available. The results obtained showed that the pattern of craniofacial size and shape variation of the Neuquén sample differed significantly from the other samples here analyzed. Similarly, the magnitude of the variation in size and shape observed for the Neuquén sample was particularly high, especially when comparing with the corresponding results for northeastern Patagonia, a region previously characterized by high degrees of morphological variation. The evaluation of the evolutionary and/or ecologic processes and events which might have originated the patterns presented here, claim for further investigations.
