Variación morfológica craneofacial en poblaciones humanas de la Quebrada de Humahuaca (Jujuy, Argentina)

A study of cranial and facial morphology in late Holocene populations from Quebrada de Humahuaca, Argentina, reveals that the most significant morphological changes occurred in the facial skeleton rather than the cranial base. These variations suggest phenotypic plasticity as a key driver, with no clear spatial patterns observed across six sites in the region. The research analyzed 114 adult skulls using 3D landmark data collected via Microscribe G2X, employing ANOVA, principal component analysis (PCA), canonical variables, and Procrustes analysis to assess morphological differences. While cultural modifications were minimal or absent, the findings highlight the importance of environmental factors in shaping facial morphology over time.
