Variación morfológica de la mandíbula en poblaciones del Pleistoceno terminal al Holoceno tardío en México

Abstract

The present work is an analysis of the morphological variation of the mandible in prehistoric remains of Mexico, whose chronology corresponds to the late Pleistocene-early and middle Holocene transition. The remains come from different parts of the Mexican territory: the basin of Mexico, the Tehuacán valley, the Puebla-Tlaxcala valley and the Yucatán Peninsula. The morphology of these specimens was compared with other mandibular samples from more recent chronological periods, from the Preclassic and Classic horizons of Mesoamerica.
From the study of 13 measures, a univariate and two multivariate analyzes were applied. The results suggest that there is a high variability in the remains of the first populations that occupied Mexico.
