Artificial cranial deformation in South America: a geometric morphometrics approximation

The bioarchaeological record of South America is characterized by the high frequency of individuals with a variety of cranial deformations concentrated in three areas (North-West, Central-West and South) of this subcontinent. The general purpose of this paper is to study the variation in artificial cranial deformation in several regions of Central-West and South of South America. Cranial variation related to artificial deformation of human cranial remains is analyzed by means of geometric morphometrics and multivariate statistic methods. The results of this work show that there are no large differences in variation among states, chiefdoms and bands of hunter-gatherers. The pattern of variation observed in cranial deformation among regions can be interpreted principally according to the chronological and spatial distribution of the cranial samples analyzed.
