Ancestral Puebloan mtDNA in context of the greater southwest

Ancient DNA (aDNA) was extracted from the human remains of seventy-three individuals from the Tommy and Mine Canyon sites (dated to PI-II and PIII, respectively), located on the B-Square Ranch in the Middle San Juan region of New Mexico. The mitochondrial DNA (mtDNA) haplogroups of 48 (65.7%) of these samples were identified, and their frequency distributions were compared with those of other prehistoric and modern populations from the Greater Southwest and Mexico. The haplogroup frequency distributions for the two sites were statistically significantly different from each other, with the Mine Canyon site exhibiting an unusually high frequency of haplogroup A for a Southwestern population, indicating the possible influence of migration or other evolutionary forces. However, both sites exhibited a relatively high frequency of haplogroup B, typical of Southwestern populations, suggesting continuity in the Southwest, as has been hypothesized by others (8, 9, 29, 45 and 57). The first hypervariable region of twenty-three individuals (31.5%) was also sequenced to confirm haplogroup assignments and compared with other sequences from the region. This comparison further strengthens the argument for population continuity in the Southwest without a detectable influence from Mesoamerica.     

Genetic relationships based on discrete dental traits: Basketmaker II and Mimbres

Investigations of the relationships between culture and biology among prehistoric populations of the southwestern United States can enhance our reconstruction of social interactions. The present study analyses the permanent dentition of Basketmaker II and Mimbres individuals from multiple sites using the Arizona State University dental anthropology system, and compares them with a regional sample. Discrete dental trait analysis provides a useful means for assessing the degree of genetic relatedness between populations when large comparative samples are available. Both in situ cultural change and population replacement have been posited as the dominant mechanism acting on Basketmaker and early Puebloan groups. We examine the relationship of these populations to probable Uto‐Aztecan speakers in light of the Uto‐Aztecan farmer migration hypothesis. The Basketmaker II complex, traditionally recognised as a distinct cultural unit, exhibits considerable population heterogeneity. Western Basketmakers appear to share biological ties with Uto‐Aztecan speakers, while Eastern Basketmakers do not, as predicted by the model. The relationship of the Mimbres to probable Uto‐Aztecan speakers is less clear because the Mimbres show only weak affinities to northern Mexican populations.

The prehistoric drug trade: widespread consumption of cacao in Ancestral Pueblo and Hohokam communities in the American Southwest

We propose the existence of extensive trade and interaction among the peoples of the American Southwest and Mesoamerica. We base this inference on our detection of the widespread presence of theobromine, the biomarker for cacao, in 50 of 75 vessels used by Ancestral Puebloans (previously referred to as Anasazi) elites and non-elites from the Four Corners area and Hohokam elites of the Gila and Salt river valleys in the prehistoric American Southwest. We used a non-invasive, non-destructive aqueous sampling procedure that provides conservation advantages over the current methods that require crushing and boiling sherds or removing residues from vessel surfaces. Analysis of these samples by sensitive LC-MS instrumentation capable of detecting nanogram quantities of material revealed theobromine in non-local vessel forms found in elite burials in great house and platform mound sites as well as in local vessel forms used by non-elites living in small unit-pueblos. After elimination of plants native to the Southwest as the source of theobromine, we conclude that either Theobroma cacao or Theobroma Bicolor was imported from its homeland in the Mesoamerican tropical coastal lowlands. Our results are at odds with the current consensus that there was little systematic commerce between Mesoamerican and Southwestern polities. We suggest that cacao was exchanged for high quality turquoise such as that mined in the Cerrillos, New Mexico mining district. We conclude that, far from being isolated developmentally, this trade integrally tied populations in the American Southwest to the socio-political and economic activities of Mesoamerican states.     

The Uncertain Origins of Mesoamerican Turkey Domestication

The turkey (Meleagris gallopavo) is the only domesticated vertebrate to originate from North America. Accurate reconstructions of the timing, location, and process of its domestication are thus critical for understanding the domestication process in the ancient Americas. A substantial amount of recent research has been devoted to understanding turkey domestication in the American Southwest, but comparatively little research has been conducted on the subject in Mesoamerica, despite the fact that all modern domestic turkeys descend from birds originally domesticated in Mexico during pre-colonial times. To address this disparity, we have conducted a review of the available literature on early turkeys in the archaeological record of Mesoamerica. We evaluate the evidence in terms of its accuracy and use this evaluation as a stepping off point for suggesting potential avenues of future research. Although the lack of available data from Mesoamerica currently precludes detailed cross-cultural comparisons, we briefly compare the origins and intensification of turkey rearing in Mesoamerica with the American Southwest to generate more dialogue among researchers independently studying the topic in these two distinct but interconnected cultural regions.     

A tale of two sites: Functional site differentiation and lithic technology during the Late Pithouse period in the Mimbres area of Southwestern New Mexico

The raw materials from which stone tools are made can provide considerable information relevant to behavioral variation within a prehistoric population. By examining the stone used for tools from two different types of Late Pithouse period (A.D. 550-1000) residential sites from the Mimbres Mogollon area of Southwestern New Mexico, this paper illustrates how understanding the lithic landscape of a region provides a means to assess behavioral variation in stone procurement practices. The analysis indicates that the differences in mobility and economic pursuits between longer-term residential sites containing pit structures and a shorter-term seasonal residential site with ephemeral architecture structured the raw material procurement practices of site’s occupants. Pit structure sites were focused on agricultural pursuits and used a technology that centered on the production of informal tools fashioned from locally available raw materials. The seasonal residential site focused on wild resources and evidenced greater reliance on formal tool production using raw materials acquired from beyond the immediate vicinity of the site. Despite increasing sedentism and agricultural dependence of the region’s population, some portion of the population exercised seasonal mobility strategies and associated technological and behavioral practices more typical of hunting and gathering populations, suggesting a diverse socio-economic system within the region.     

Ancient DNA,a Neolithic legging from the Swiss Alps and the early history of goat

Ancient DNA from a Neolithic legging (1st half of the 3rd millennium BC) found at Lenk, Schnidejoch (2750 m a.sl.) in the Swiss Alps has demonstrated, that modern distribution of genetic variation does not reflect past spatio-temporal signatures. The legging was made from the skin of a domestic goat (Capra hircus), belonging to the caprine haplogroup B1, which is marginal in Europe today, but represents a third highly diverse goat haplogroup entering Europe already in the Neolithic. Population expansion of lineage B therefore happened more than 4500 years ago, but their members were at some point almost completely replaced by goats of today's common A and C haplogroups.     

Painting as Agency,Style as Structure: Innovations in Mimbres Pottery Designs From Southwest New Mexico

The act of painting a design is a form of agency, and the overall style of that design in part can be conceptualized as a kind of structure. This perspective is used as a basis for analyzing chronological changes in designs on Mimbres Black-on-white pottery (ca. AD 750–1150) from Southwest New Mexico. Specific focus is on a methodology that can be used to detect innovations, that is, the introduction of novel designs that are incorporated into the design corpus and thus transform the structure. The conceptualization of a particular tradition (in this instance, pottery painting) as a form of structure analogous to general structure in Giddens' sense thus provides important insights into the recursive relationship between agency and structure.     

Large game, agricultural land, and settlement pattern change in the eastern Mimbres area, southwest New Mexico

The 12th-century depopulation of large villages in the Mimbres region of the US Southwest has been attributed to a number of causes, including resource stress. This study combines archaeological evidence and models of environmental conditions in the eastern Mimbres area of southwest New Mexico to assess the magnitude and timing of food stress from a combination of a period of reduced precipitation and the effects of prolonged hunting and farming activities on the landscape. Results indicate that large game in the area was quite sensitive to hunting pressure, and was locally depleted long before settlement reorganization occurred. Access to arable land was somewhat reduced around the time of settlement reorganization, but productive land remained locally plentiful. Although the settlement reorganization did not improve access to large game or arable land, farmers’ perceptions of below-average conditions for agriculture relative to their expectations and past experience would have contributed to decisions to move.     

Recent Issues in the Archaeology of the Mimbres Region of the North American Southwest

Archaeological research in the Mimbres region (southwestern New Mexico) has focused on the post-A.D. 500 ceramic/agricultural occupations, especially the Mimbres Classic period (1000–1130). This work has advanced general anthropological issues regarding mobility, land use and human impact, and the concept of abandonment. Deeper understandings of some of these issues require more detailed demographic estimates, which in turn are dependent on methodological advances, particularly studies of site use life. Research on the production and distribution of Mimbres pottery—famous for its naturalistic black-on-white designs—is advancing rapidly. Although the designs have been well illustrated and much discussed, more systematic anthropological research on Mimbres design style is badly needed. Various aspects of Mimbres social and ideational realms (e.g., household and community organization, social hierarchy, the symbolism of the pottery designs) have received some attention but await new perspectives derived from current social theory.     

Temporal frequency distributions of alluvium in the American Southwest: taphonomic,paleohydraulic, and demographic implications

The use of radiocarbon frequency distributions to reconstruct prehistoric human and animal populations must account for taphonomic loss and other factors that affect the archaeological and paleontological records. Surovell et al. (JAS, 36, 1715–1724) have recently proposed a correction for “taphonomic bias” that is based on the radiocarbon frequency of a global sample of volcanic deposits. Analysis of 717 radiocarbon dates sampled from the alluvium of the San Pedro and Santa Cruz rivers and their tributaries in southeastern Arizona shows that discovery and scientific biases also play an important role in the creation of radiocarbon frequency distributions, and that the rate of “taphonomic bias” in prehistory is not predicted by the radiocarbon frequency of volcanic deposits. The latter principle is further argued using a sample of 123 Pliocene to Clovis-age proboscideans from the San Pedro Valley. We propose an alternative model that is based on the nature of the stratigraphic record, with discovery bias, scientific bias, taphonomic loss, and the shape of the calibration curve all operating to influence the temporal frequency distribution of radiocarbon-dated prehistoric phenomena.     

Animate Objects: Shell Trumpets and Ritual Networks in the Greater Southwest

For over a millennium, shell trumpets have been an important part of Southwestern US ritual practice. We investigate the distribution of Southwestern shell trumpets, arguing that they are objects that are accorded animacy and can be used to track the history of different social networks. Using ethnohistoric and ethnographic documentation, at least two traditions of historically linked ritual practices are identified: one associated with serpent iconography and the other with curing, warfare, and sorcery. These two traditions represent enduring dispositions that link various regions of the Southwest through the introduction and adoption of ritual practices associated with migration and the transformation of late prehistoric societies.     

Cultural Effects on Phenetic Distances Among Postclassic Mexican and Southwest United States Populations

The Southwest United States (US) and Mesoamerica are often thought of as disparate regional networks separated by Northern Mexico. Chaco Canyon in the Southwest US, Tlatelolco in Central Mexico and Casas Grandes in Northern Mexico, all had large inter‐regional trade centres that economically connected these networks. This study investigated how factors such as geographic distance, shared migration history, trade and political interaction affected biological relationships and population affinities among sites in Mexico and in Southwest US during the Postclassic period (ad 900 ~ 1520). Distances based on cultural and geographic variables derived from archaeological and ethnohistoric data were compared with phenetic distances obtained from dental morphological traits. The results of Mantel tests show trade (corr = 0.441, p = 0.005), shared migration history (corr = 0.496, p = 0.004) and geographic distance (corr = 0.304, p = 0.02) are significantly correlated with phenetic distances, whereas political interaction (corr = 0.157, p = 0.133) is not. Partial Mantel tests show trade (corr = 0.223, p = 0.049) and shared migration history (corr = 0.493, p = 0.003) remain significant when controlling for similarities with geographic distance, although the correlation for trade and phenetic distance is lowered. Geographic distance is not significant when similarities with trade (corr = 0.067, p = 0.681) and shared migration history (corr = 0.148, p = 0.127) are controlled. These results highlight the importance of economic relationships and shared migration history across geographic regions in interpreting biological relationships among contemporaneous populations in prehistoric Mexico and the Southwest US.

Mitochondrial DNA diversity in a Transbaikalian Xiongnu population

Xiongnu was a confederation of nomadic pastoral tribes (~200 bc–100 ad) that founded the first nomadic empire in Central Asia. According to archeological and historical data, the tribes played a key role in ethnic and cultural processes in Central Asia and adjacent regions of Eurasia. Genetic studies of the Xiongnu published to date have focused on remains from burial grounds in present-day Mongolia, in the southern part of the ancient Xiongnu area. However, paleoanthropological materials from numerous Xiongnu cemeteries and settlements in Transbaikalia (the southern region of Eastern Siberia, Russia) in the northern part of the Xiongnu Empire have not been examined genetically. Here, we analyzed mitochondrial DNA variation in a Transbaikalian Xiongnu population based on ancient DNA obtained from skeletal remains (n = 18) at four burial grounds to complement available Xiongnu genetic diversity data. We detected 16 mitochondrial DNA haplotypes belonging to seven East Eurasian haplogroups (A, B5, C, D4, G2a, N9a, and Y) in the Transbaikalian Xiongnu series. We observed substantial similarity between Transbaikalian and Mongolian Xiongnu series with respect to main haplogroup composition and frequencies. We observed several mitochondrial DNA clusters (N9a, Y, B5, and A16) and 11 of 16 haplotypes that were previously undetected in the Xiongnu gene pool. We also observed high similarity between the Xiongnu and contemporary indigenous populations of eastern Central Asia, particularly Mongolian-speaking groups. These findings extend our knowledge of Xiongnu genetic diversity.

Frequency of Complete Cleft Sacra in a Native American Sample

The purpose of this paper is to contribute to the current understanding of the variability of complete sacral clefts in human populations by presenting new data on a large prehistoric and historic Native American skeletal sample (n = 1943). Results are examined by age, sex, time period, and regional distribution and compared with reported frequencies of complete sacral clefts in other modern, historic, and ancient populations. In all, 1.6% of the sample exhibited complete sacral clefts, including 2.1% of males and 1.1% of females. Although males exhibit a frequency twice as high as females, this difference is not statistically significant. However, within the Alaskan sample, the sex difference was significant (p = 0.002), with 3.4% of males and 0.5% of females exhibiting complete clefts; these differences may be related to mechanical influences during growth and development in males. Differences among age groups are not significant. Regional comparisons among Alaska, Eastern Woodlands, Great Basin/Northwest/California, Great Plains, and Southwest showed no significant differences overall, but Alaska (2.2%) and Great Plains (0.5%) do show a significant difference (p = 0.024). No significant differences were found between prehistoric, protohistoric, and historic/recent samples, suggesting a lack of a secular trend in frequency of complete sacral clefts in Native American populations. One individual exhibited an enlarged canal, which may be indicative of a more severe condition. Copyright © 2012 John Wiley & Sons, Ltd.     

Recent research in west Mexican archaeology

The last decade has seen the greatest increase in archaeological research in western Mexico since the 1940s. Unlike previously heralded renewals, this one is accompanied by widespread skepticism of the dominant culture-historical paradigm linking west Mexico to the rest of Mesoamerica, to the American Southwest, and to South America. Current research offers substantive new data and interpretations bearing on issues such as the definition of Mesoamerica, the role of South American long distance contacts, the human ecology of highland lakes, the role of river systems in Mesoamerican prehistory, and the nature/role of prehispanic elite exchanges.     

Culturally modified skeletal remains from the site of Huamelulpan,Oaxaca, Mexico

A series of crania from the site of Huamelulpan, Oaxaca, Mexico (400 BC to AD 800), were examined. Four showed notable cultural modifications. One exhibited a healed trephination, while the other three were perforated through the frontal. The cultural context and significance of these modifications is discussed, especially in relationship to the site of Monte Albán, where trephination was more common than anywhere else in Mesoamerica. The post-mortem cranial perforations appear to be connected with the practice of ancestor veneration. © 1997 John Wiley & Sons, Ltd.     

3400 years of agricultural engineering in Mesoamerica: lama-bordos of the Mixteca Alta,Oaxaca, Mexico

The origins of early Mesoamerican agricultural techniques are not well established. Our charcoal-derived radiocarbon chronology dates cross-valley check dams, or lama-bordos, buried by up to 11.5 m of sediment in arroyos near Coixtlahuaca, Oaxaca, Mexico. Now it is clear that people in highland Mexico built lama-bordos at least 3400–3500 years ago, several hundred years earlier than previously dated engineering systems in Mesoamerica. Lama-bordo systems evolved as intensively and extensively managed landscapes coeval with climate shifting to more arid conditions. They provide clear examples of human-produced stratigraphy and artificial landscapes (stair-stepped valleys). More importantly, these lama-bordo systems signal a major cultural tipping point toward sedentary agricultural life and solidify our understanding of the Neolithic transition in Mesoamerica.     

Obsidian procurement,least cost path analysis,and social interaction in the Mimbres area of southwestern New Mexico

For over 15 years chemical compositional analyses of obsidian artifacts recovered from archaeological sites in the southwestern United States have been increasingly used to address many research agendas. Despite this increasing interest in obsidian studies, few have attempted to synthesize the ever-growing amount of data generated from the numerous projects being conducted in the southwest. Here, we synthesize and present data for 923 sourced obsidian samples recovered from over 80 archaeological sites in the Mimbres area of southwestern New Mexico. We then use least cost path analysis as a means of investigating procurement patterns as well as networks of social interaction within the region.     

Mitochondrial DNA Analysis of Ancient Domestic Goats in the Southern Caucasus: A Preliminary Result from Neolithic Settlements at Göytepe and Hacı Elamxanlı Tepe

This study presents preliminary results of mitochondrial DNA analyses of modern and ancient domestic goats in the southern Caucasus in order to examine their phylogenetic relationship with modern and ancient goats. For this purpose, seven ancient samples were obtained from two early agricultural villages in west Azerbaijan (Göytepe and Hacı Elamxanlı tepe, dated to ca. 6000–5500 cal bc , the Pottery Neolithic period), in addition to five modern goat samples in the same region. In the study, mitochondrial DNA segments of the control region (216 bp for the Neolithic samples and 481 bp for the modern samples) were amplified, and phylogenetic analyses were performed using previously published reference DNA sequences. As a result, all the haplotypes found in this study were grouped in the haplogroup A of goats. The finding of the haplogroup A among domestic goats in the southern Caucasus in the early sixth millennium bc can be interpreted as part of the geographic expansion of this lineage from the areas of initial domestication to surrounding areas that include also South and Southeast Europe. In the southern Caucasus, the haplogroup A probably continued to be a major lineage among domestic goats since their emergence in this area to the present. In contrast, this lineage has not been detected among local wild goats including Capra aegagrus , indicating the external origin of domestic goats. This possibility is consistent with archaeological records that indicate sudden appearance of agricultural lifeways in the southern Caucasus and cultural connections with northern Mesopotamia.
