| dc.description | Se estudia la estructura de la población prehistórica del NOA a través del análisis de la variabilidad fenotípica a nivel regional. La muestra está constituida por 961 individuos deformados y no deformados artificialmente, de ambos sexos, de edades post-reproductivas, pertenecientes a cuatro subregiones (Puna, Quebrada de Humahuaca, Valliserrana y Selvas Occidentales).
Se emplearon 35 caracteres métricos del neuro y esplacnocráneo. La variabilidad entre poblaciones se evaluó mediante el empleo de diferentes técnicas de análisis estadístico multivariado, tales como análisis discriminante, D2 de Mahalanobis, análisis de agrupamiento, y correlación entre matrices de distancias. Los resultados indican que las relaciones biológicas entre subregiones no cambian cuando son obtenidas con cráneos deformados artificialmente o con cráneos sin deformación. Además, se comprueba la existencia de dos conglomerados biológicos, uno integrado por Valliserrana y Selvas Occidentales y otro constituido por Puna y Quebrada de Humahuaca.
Por último, se demuestra que este modelo es globalmente consistente con el obtenido a partir de caracteres discretos del cráneo. | |
| dc.description | The structure of the prehistoric population of Northwest Argentina is studied through the analysis of the phenotypic variability at a regional scale. The sample includes 961 artificially deformed and not deformed individuals, of both sexes, of post-reproductive ages belonging to four subregions (Puna, Quebrada of Humahuaca, Valliserrana and Selvas Occidentales). Thirty-five craneometric traits were examined. The variability among populations was evaluated by different techniques of multivariate statistical analysis (discriminant analysis, Mahalanobis´ D2, cluster analysis, and correlation among matrix distances).
Results show that the biological relationships among subregions do not change when they are obtained with deformed skulls or skulls without deformation. Additionally, the existence of two biological conglomerates is identified, the first one is conformed by Valliserrana and Selvas Occidentales and the second by Puna and Quebrada of Humahuaca. We also show that this model is globally consistent with the one obtained from nonmetric cranial traits. Both components possibly shared the same ancestral group, probably of Andean origin, and then differed through the action of evolutionary factors (particularly mating systems, genetic drift, and gene flow). | |
