“…We also find two additional major clades: a grouping of populations from the southern states of Guerrero and Oaxaca (green labels) and a “Mayan clade” composed of Mayan-speaking populations from Chiapas and the Yucatan peninsula in the southeast (orange labels). Introducing migratory edges to the model connects the Maya in Yucatan to a branch leading to the Totonac, whose ancestors occupied the large pre-Columbian city of El Tajin in Veracruz (15). This result points to an Atlantic coastal corridor of gene flow between the Yucatan Peninsula and Central/Northern Mexico (fig.…”

Mexico harbors great cultural and ethnic diversity, yet fine-scale patterns of human genome-wide variation from this region remain largely uncharacterized. We studied genomic variation within Mexico from over 1,000 individuals representing 20 indigenous and 11 mestizo populations. We found striking genetic stratification among indigenous populations within Mexico at varying degrees of geographic isolation. Some groups were as differentiated as Europeans are from East Asians. Pre-Columbian genetic substructure is recapitulated in the indigenous ancestry of admixed mestizo individuals across the country. Furthermore, two independently phenotyped cohorts of Mexicans and Mexican Americans showed a significant association between sub-continental ancestry and lung function. Thus, accounting for fine-scale ancestry patterns is critical for medical and population genetic studies within Mexico, in Mexican-descent populations, and likely in many other populations worldwide.
