Since Spanish colonization in 1521, gene flow and admixture have been important microevolutionary processes modelling the Armerindian genetic structure in Mexico. The present study tests the effects of admixture on craniofacial morphology by means of geometric morphometrics and multivariate statistical methods, including Thin-plate spline and Canonical variate analysis. 19 landmark coordinates were recorded on the lateral profile of 106 complete adult skulls representing two ancestor populations and a colonial population form Mexico DF. Results showed marked craniofacial differences between Spanish and Amerindians individuals and pointed out a different morphological pattern for the Colonial population, which retained the facial Amerindian morphology but was highly influenced by the posterior neurocranial Spanish pattern.
