This paper presents the results obtained from an anthropolgical dental analysis carried out on two contemporary samples obtained from the Yucatan Peninsula, Mexico; to do this, first, the Average Divergence Measurement between the two samples was taken, then, applying the same methodology, a comparative analysis was carried out on several populations worldwide, along with a multivariate analysis of multidimensional scaling, which provided results that demonstrate that the Yucatan populations, although very similar to each other, registered a differing level of mixed-race European influence, given that the locality of Xpujil, in the Southern part of the Yucatan Peninsula, demonstrates a lower grade of European influence compared with the average, thus supporting the position that throughout the contemporary history of the Mexican Republic, the mixing process has been unequal in different regions of the national territory and that the most (geographically) marginalized populations have seen lower levels of mixing, thus demonstrating that the ancestral Mesoamerican gene pool has -to a certain extent- been maintained.
