“…Our results also support the expansion of maize with the human populations from the Mexican Gulf Coast to the south, as maize cultivation was dispersed from the lowland tropics of Tabasco earlier than 5,050 BCE to North and South America (Pohl et al 2007;Merrill et al 2009). This finding is consistent with the introduction of maize into the US Southwest prior to 2050 BCE (Merrill et al 2009;Kohler and Reese 2014), according to the population expansion from the Maya area to North and South America (Figure 4) through the long-distance migration of farmers from the Mexican Gulf Coast (Malhi et al 2003). These results support the historically based migration theories supported by archaeological data.…”

“…Furthermore, a phytolith analysis of sediments from San Andres, Tabasco, confirmed the diffusion of maize cultivation from the tropical Mexican Gulf Coast >7,000 years ago (~5800 BCE), followed by the rapid spread of the crop to South and North America by the ancestors of the Maya (Pohl et al 2007;da Fonseca et al 2015;Piperno et al 2009;Grobman et al 2012). This diffusion is further supported by evidence suggesting that the introduction of maize into the Southwest United States occurred before 2050 BCE (Merrill et al 2009;Kohler and Reese 2014).…”

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.

“…Sattenspiel and Harpending (1983) and Paine (1989), among others, have described the problem of demographic nonstationarity from a bioarchaeological perspective. Several researchers have proposed methods that address the probable violation of the stationarity assumption in past populations, such as using models that allow for the estimation of population growth rates or using proxies for birth rates based on the proportions of subadults in skeletal samples Buikstra et al 1986;Kohler and Reese 2014;White 2014;Wood et al 2002). Archaeological research is also addressing migration and population growth (or decline) through isotope analysis (e.g., Beaumont et al 2013;Keenleyside et al 2011;Knudson et al 2012), ancient DNA studies (e.g., Li et al 2011;O'Fallon and Fehren-Schmitz 2011;Raff et al 2011), biodistance analysis (e.g., McIlvaine et al 2014;Torres-Rouff et al 2013), and GIS-based analyses of settlement patterns and trends in population size (Jones 2010(Jones , 2014.…”

The Osteological Paradox 20 Years Later: Past Perspectives, Future Directions

More than 20 years ago, Wood et al. (Curr Anthropol 33:343-370, 1992) published ''The Osteological Paradox: Problems of Inferring Prehistoric Health from Skeletal Samples,'' in which they challenged bioarchaeologists to consider the effects of heterogeneous frailty and selective mortality on health inferences in past populations. Here, we review the paper's impact on bioarchaeology and paleopathology, focusing on recent advancements in studies of ancient health. We find the paper is often cited but infrequently engaged in a meaningful way. Despite an initial decade of limited progress, numerous researchers are now addressing components of the Paradox in more informed ways. We identify four areas of fruitful research: (1) intrasite, contextual perspectives, (2) subadults, (3) associating stress markers with demographic phenomena, and (4) skeletal lesion-formation processes. Although often seen as a problematic assumption, understanding the sources of heterogeneous frailty within human populations is a worthy research question in and of itself, and one that clearly links past and present health research within a global framework.

“…The median age at death was sometime during the third decade of life (20-35 years old) and very few adults survived into older adulthood (>45 years old). These patterns in mortality are fairly common to late pre-contact populations in the region (Kohler and Reese 2014;McClelland 2015).…”
