Resumen
El propósito del presente trabajo fue analizar la variación morfológica craneofacial en poblaciones humanas que habitaron la Quebrada de Humahuaca durante el Holoceno tardío. Se estudiaron los cambios en forma y tamaño del esqueleto facial y base craneana, y se evaluó la distribución de la variación morfológica craneofacial en el espacio geográfico. Para esto, se seleccionaron 114 cráneos de individuos adultos de ambos sexos que no presentasen modificaciones culturales o las presentasen en un grado muy leve, procedentes de seis sitios del sector medio de la Quebrada. Se relevaron 41 puntos anatómicos en 3D con un brazo mecánico Microscribe G2X. Para evaluar la variación morfológica se realizó un ANOVA, se calcularon componentes principales y variables canónicas; mientras que la asociación entre morfología y variación espacial fue evaluada a través de un análisis de Procrustes. Los resultados indican que la variación craneofacial difiere según se considere el esqueleto facial ó la base. Dado que los mayores cambios se registraron en la región facial, la variación morfológica podría ser explicada como producto de la plasticidad fenotípica. Asimismo, no se encontró relación entre la variación morfológica y la distribución geográfica de las muestras.
The aim of this paper was to analyze the craniofacial morphological variation in human samples showing no cultural modifications of the skull, belonging to populations that lived in the Quebrada de Humahuaca during the late Holocene. Shape and size alterations of the facial skeleton and skull base were studied, and the spatial distribution of morphological variables was evaluated. For this purpose, 114 skulls of adult men and women with slight or absent cultural modifications, from six archaeological sites in the middle section of the creek grade were selected. Forty-one anatomical points were registered in 3-D with a mechanical arm Microscribe G2X. To assess morphological variation an ANOVA as well as principal components and canonical variables. The association between morphology and geographic variation was assessed through a Procrustes analysis. Results indicate that craniofacial variation differs between facial skeleton and base. As the biggest change is found on the facial skeleton, morphological variation could be explained as a product of phenotypic plasticity. Also, no relationship between morphological variation and geographic distribution of the samples was found.
