Postcranial directional asymmetry in southern-South America populations

Mostrar todas las versiones(3)

The purpose of this study is to analyze directional asymmetry patterns in the size of long bones of hunter-gatherer aboriginal populations of southern South América. Postcranial variables of 272 adult individuals of both sexes were measured, belonging to five samples from Pampa, Patagonia and Norwes...

Postcranial variables of 272 adult individuals of both sexes were measured, belonging to five samples from Pampa, Patagonia and Norwestern Argentina, and from the northern coast of Chile. Data from 139 adult individuals of both sexes, belonging to three samples from northern, southeastern and southwestern North América were also collected for reference. The entire data set was analyzed in terms of laterality, magnitude, sexual dimorphism and subsistence patterns. Results show significant differences in directional asymmetry of the upper limb, particularly in the diaphyseal diameter of the humerus. In turn, these results suggest that subsistence patterns, at least as they were considered in this study, are not an adequate environmental variable to explain asymmetry patterns in the examined populations. El objetivo de este trabajo es estudiar los patrones de asimetría direccional en el tamaño de los huesos largos en poblaciones aborígenes de cazadores-recolectores y agricultores del sur de Sudamérica. Se midieron variables del postcráneo de 272 individuos adultos de ambos sexos correspondientes a cinco muestras de las regiones pampeana, patagónica y Noroeste de Argentina y de la Costa y Valle de Azapa, en el Norte de Chile. Asimismo, se recolectaron datos de 139 individuos adultos de ambos sexos correspondientes a tres muestras del Norte, Sudeste y Sudoeste de Norteamérica. Los datos obtenidos se analizaron en términos de lateralidad y magnitud, dimorfismo sexual y diferencias por modo de subsistencia. Los resultados muestran diferencias significativas en la asimetría direccional en el miembro superior, particularmente en el diámetro de la diáfisis del húmero. A su vez, estos resultados sugieren que el modo de subsistencia, al menos en las categorías consideradas en este trabajo, no es una variable ambiental adecuada para explicar los patrones de asimetría direccional entre las poblaciones estudiadas.
