Resumen:
Objectives We study the genetic diversity between Classic Teotihuacan
and its neighboring towns trying to understand how far or close they are
at the genetic level. Materials and methods We use cranial nonmetric
traits to study a sample of 280 adult skulls from archaeological sites
running from the late Preclassic to the early Postclassic. Samples of
Classic Teotihuacan were studied for La Ventilla and San Sebastian
Xolalpan neighbors. For the Epiclassic period, samples from Xaltocan,
Toluca valley, Mogotes and Xico were used. For the Preclassic and
Postclassic samples from Xico were also used. We used a parametric
bootstrap for the mean measure of divergence for the statistical
analysis. Results Samples from Xico have small biodistance from
Preclassic to Postclassic. Samples from Los Mogotes differ depending on
the functional context of deposition, with individuals from household
burials (funerary) differing from non-funerary, ceremonial interments
and exhibiting affinities to Epiclassic samples from Toluca valley.
Epiclassic populations from Xaltocan vary significantly from any samples
analyzed. Samples from Classic period Teotihuacan vary considerably
among them but form a separate genetic group from all the other
populations under study. Conclusions The great biodistance separation
among Classic Teotihuacan and its neighbor villages of central Mexico
let us conclude that, contrary from the classical idea that those
villages were confirmed by the inhabitants of Teotihuacan's collapse:
They indeed remain as separate populations by themselves.
