Numerous studies have used the Howells Peruvian sample from the province of Yauyos as the morphological representative for South America. Although Peru has a rich history of investigations of human skeletal remains, biological distance studies based on craniometrics are limited to nonexistent. This study examines the morphological variation found in Peru using the Howells sample and three additional coastal (Makatampu and Ancón) and highland (Cajamarca) samples. The between-group variation and the degree of among-group differentiation were tested using a canonical discriminant analysis and Mahalanobis D², respectively. All groups are significantly different from the Yauyos sample and results indicate a closer morphological affinity between coastal groups and the two highland groups.
Numerosos estudios han utilizado la muestra peruana de Howells de la provincia de Yauyos como el representante morfológico para Sudamérica. Aunque Perú tiene una historia rica de investigaciones de restos óseos humanos, los estudios de variación biológica basados en las medidas craniométricas son limitados. Este estudio examina la variación morfológica encontrada en el Perú usando la muestra de Howells y tres muestras adicionales de la costa (Makatampu y Ancón) y la sierra (Cajamarca) peruana. Los materiales empleados en este trabajo están depositados en el Museo Nacional de Arqueología, Antropología e Historia de la ciudad de Lima. La variación morfométrica y el grado de diferenciación biológica fueron probados usando un análisis multivariado de los valores D² de Mahalanobis como distancias morfométricas entre pares de muestras. Todos los grupos son perceptiblemente diferentes de la muestra de Yauyos y los resultados indican una afinidad morfológica más cercana entre los grupos costeros y el grupo serrano y demuestra que la muestra original de Howells no refleja adecuadamente la variación morfométrica peruana.
