Mesoamerica is a cultural and geographic region with a northern boundary adjacent to the American Greater Southwest and a southeastern boundary that includes the Maya area, which is adjacent to the Caribbean. These regions are of interest to analyze genetic structure, ancestry, and gene flow between the ancient populations. We identified the mitochondrial DNA haplogroups and haplotypes in 19 colonial and 10 pre-Columbian Maya from Xcaret and 6 Paquimé individuals. We analyzed our data together with 603 ancient individuals and with 95 colonial and 502 pre-Columbian individuals. The results show clear genetic differences among Mesoamerica, American Greater Southwest, and Caribbean regions. High frequency of haplogroup A in Paquimé and Mine Canyon and the distribution of its haplotypes in the networks suggest these populations are probably genetically related with both Mesoamerican and the American Greater Southwest populations. The genetic structure of the Maya is due to common ancestry, and it was maintained by geographic isolation and gene flow mostly between Mayan populations. The Spanish conquest did not change this structure in the Maya from Xcaret, Quintana Roo. Although populations from Central Mexico are not genetically homogeneous, they are clearly different from Maya. Teotihuacan and Cholula were contemporary cities that allied to control the region, but they show genetic differences that could be related to a distant common ancestry; they probably descended from the same group but separated very early, before their arrival in Central Mexico.

We identified the mitochondrial DNA haplogroups A, B, C and D in 75 present-day Maya individuals, 24 Maya individuals of the colonial period and one pre-Columbian Maya individual from Quintana Roo, Mexico. We examined these data together with those of 21 Maya populations accounting for 647 present-day Maya individuals and 104 ancient Maya individuals. A demographic study based on the analysis of fertility and endogamy was carried out in two modern Maya populations to identify cultural factors that influence the mitochondrial haplogroup genetic diversity. Most present-day and ancient Maya populations show a distribution pattern of mitochondrial haplogroup frequencies A, C, B and D in decreasing order, with haplogroup D absent in several populations. Considering only modern Maya populations with at least 50 individuals analyzed, the present-day Tzotzil and Lacandon populations from Chiapas show the higher and lower genetic diversities, 0.706 and 0.025 respectively. Our results show small genetic differences between the Maya populations with exception of the present-day Tojolabal and Lacandon populations from Chiapas. The present-day Lacandon population from Chiapas is different to other Maya populations in showing almost only haplogroup A. This result suggests a long history of isolation and endogamy as well as a possible founder effect inside the Lacandonian rain-forest. The contemporary Tojolabal population is the only one with an unusual mitochondrial haplogroup pattern exhibiting a frequency of haplogroup B higher than A and the absence of haplogroup C. With a small sample size, the pre-Columbian Copan Maya show a high content of haplogroup C and a low frequency of haplogroup D. The genetic homogeneity of the Maya populations is indicative of a common origin and nearly continuous gene flow in the longterm within a general isolation of the whole group, conversely to the Nahua populations that had different origins. Our demographic study showed high fertility rates and high levels of endogamy Pre-print version.

The population size fluctuated geographically and temporally with a tendency to increase in the cities. The Maya were divided in autonomous political entities, maintaining multiple networks through commerce, warfare, and migration that influenced their economic, cultural, and demographic development (Renfrew 1975;Schele and Freidel 1990;Folan et al. 2000;Sierra et al. 2014).Evidence of far-reaching commerce, exchange of elite individuals through marriage, and non-elite population mobility suggests a degree of genetic flow among Mayan populations in the

“…Holocene population dynamics left their mark in other regions of North America as well. In the midwestern United States, for example, mtDNA data from burial populations spanning the last 3,000 years provide evidence for genetic continuity across both time and space (Shook & Smith 2008, Raff et al 2011, Marshall & Kaestle 2013, Reynolds et al 2015. This pattern likely reflects demographic stability through time in the region, as well as a long history of gene flow among populations in association with the extensive trade networks that connected indigenous communities across eastern North America for thousands of years.…”

Studies of Native American genetic diversity and population history have been transformed over the last decade by important developments in anthropological genetics. During this time, researchers have adopted new DNA technologies and computational approaches for analyzing genomic data, and they have become increasingly sensitive to the views of research participants and communities. As new methods are applied to long-standing questions, and as more research is conducted in collaboration with indigenous communities, we are gaining new insights into the history and diversity of indigenous populations. This review discusses the recent methodological advances and genetic studies that have improved our understanding of Native American genomics and population histories. We synthesize current knowledge about Native American genomic variation and build a model of population history in the Americas. We also discuss the broader implications of this research for anthropology and related disciplines, and we highlight challenges and other considerations for future research.
