“…Of further note, within haplogroup A, one clade containing a Tohono O'odham and Zuni [derived by nucleotide positions (nps) 16257T and 16263A] is of interest, because this form of haplogroup A is only found elsewhere among the Chumash of Southern California (43). Combined with the absence of shared derived forms of haplogroup A across the regions, this cautions against the interpretation that haplogroup A in the Southwest was introduced by farmers from Mesoamerica (49), where haplogroup A is far more common.…”

The Farming/Language Dispersal Hypothesis posits that prehistoric population expansions, precipitated by the innovation or early adoption of agriculture, played an important role in the uneven distribution of language families recorded across the world. In this case, the most widely spread language families today came to be distributed at the expense of those that have more restricted distributions. In the Americas, Uto-Aztecan is one such language family that may have been spread across Mesoamerica and the American Southwest by ancient farmers. We evaluated this hypothesis with a large-scale study of mitochondrial DNA (mtDNA) and Y-chromosomal DNA variation in indigenous populations from these regions. Partial correlation coefficients, determined with Mantel tests, show that Y-chromosome variation in indigenous populations from the American Southwest and Mesoamerica correlates significantly with linguistic distances (r = 0.33-0.384; P < 0.02), whereas mtDNA diversity correlates significantly with only geographic distance (r = 0.619; P = 0.002). The lack of correlation between mtDNA and Y-chromosome diversity is consistent with differing population histories of males and females in these regions. Although unlikely, if groups of Uto-Aztecan speakers were responsible for the northward spread of agriculture and their languages from Mesoamerica to the Southwest, this migration was possibly biased to males. However, a recent in situ population expansion within the American Southwest (2,105 years before present; 99.5% confidence interval = 1,273-3,773 YBP), one that probably followed the introduction and intensification of maize agriculture in the region, may have blurred ancient mtDNA patterns, which might otherwise have revealed a closer genetic relationship between females in the Southwest and Mesoamerica.mtDNA | Uto-Aztecan | Y chromsome | maize | migration

“…The haplogroup frequency differences between these sites were statistically significant. The population of the Tommy site, with a high frequency of haplogroup B, most closely resembled the ancient Anasazi and Fremont (Carlyle et al, 2000;Leblanc et al, 2007), as well as the modern populations of Jemez and Zuni. The population from the Mine Canyon site resembled ancient/extant Mesoamerican populations (Mixtec, Nahua, Maya) and southern Athapascans (Apache and Navaho) in having a high frequency of haplogroup A.…”

Ancient DNA (aDNA) analyses have proven to be important tools in understanding human population dispersals, settlement patterns, interactions between prehistoric populations, and the development of regional population histories. Here, we review the published results of sixty-three human populations from throughout the Americas and compare the levels of diversity and geographic patterns of variation in the ancient samples with contemporary genetic variation in the Americas in order to investigate the evolution of the Native American gene pool over time. Our analysis of mitochondrial haplogroup frequencies and prehistoric population genetic diversity presents a complex evolutionary picture. Although the broad genetic structure of American prehistoric populations appears to have been established relatively early, we nevertheless identify examples of genetic discontinuity over time in select regions. We discuss the implications this finding may have for our interpretation of the genetic evidence for the initial colonization of the Americas and its subsequent population history.

“…In contrast, a 650-1200 CE Maya sample from Copán, Honduras, exhibited a high frequency of haplogroup C (Merriwether et al 1997), and the 800-1100 CE from the Tommy site in the United States (Snow et al 2010) showed a high frequency of haplogroup B, most closely resembling the ancient Anasazi at Fremont (Carlyle et al 2000;LeBlanc et al 2007) and the modern populations of Cora, Hualapai, Huichol, Jemez, Tarahumara, Tohono O'odham, and Zuni , the Tojolabal Maya (González-Martín et al 2015), and US Southwest and South America (Salas et al 2009;Raff et al 2011). Therefore, contemporary Maya are descendants of the pre-Hispanic Maya, and the ancestral Native Americans dispersed across North America approximately 13,000 years ago (Raghavan et al 2015).…”

Maya civilization developed in Mesoamerica and encompassed the Yucatan Peninsula, Guatemala, Belize, part of the Mexican states of Tabasco and Chiapas, and the western parts of Honduras and El Salvador. This civilization persisted approximately 3,000 years and was one of the most advanced of its time, possessing the only known full writing system at the time, as well as art, sophisticated architecture, and mathematical and astronomical systems. This civilization reached the apex of its power and influence during the Preclassic period, from 2000 BCE to 250 CE. Genetic variation in the pre-Hispanic Mayas from archaeological sites in the Mexican states of Yucatan, Chiapas, Quintana Roo, and Tabasco and their relationship with the contemporary communities in these regions have not been previously studied. Consequently, the principal aim of this study was to determine mitochondrial DNA (mtDNA) variation in the pre-Hispanic Maya population and to assess the relationship of these individuals with contemporary Mesoamerican Maya and populations from Asia, Beringia, and North, Central, and South America. Our results revealed interactions and gene flow between populations in the different archaeological sites assessed in this study. The mtDNA haplogroup frequency in the pre-Hispanic Maya population (60.53%, 34.21%, and 5.26% for haplogroups A, C, and D, respectively) was similar to that of most Mexican and Guatemalan Maya populations, with haplogroup A exhibiting the highest frequency. Haplogroup B most likely arrived independently and mixed with populations carrying haplogroups A and C based on its absence in the pre-Hispanic Mexican Maya populations and low frequencies in most Mexican and Guatemalan Maya populations, although this also may be due to drift. Maya and Ciboneys sharing haplotype H10 belonged to haplogroup C1 and haplotype H4 of haplogroup D, suggesting shared regional haplotypes. This may indicate a shared genetic ancestry, suggesting more regional interaction between populations in the circum-Caribbean region than previously demonstrated. Haplotype sharing between the pre-Hispanic Maya and the indigenous populations from Asia, the Aleutian Islands, and North, Maternal Lineage in Pre-Hispanic and Contemporary Mayas ■ 137Central, and South America provides evidence for gene flow from the ancestral Amerindian population of the pre-Hispanic Maya to Central and South America.
