Skeletons drawn from archaeological contexts provide a fund of data for assessing disease in general and timing of epidemics in particular in past societies. The bioarchaeological record presents an especially important perspective on timing of some of the world's most catastrophic diseases, such as leprosy, tuberculosis, plague (Black Death), and treponematosis. Application of new developments in paleogenomics and paleogenetics presents new opportunities to document ancient pathogens' DNA (for example, Black Death), track their history, and assess their beginning and end points. Paleopathological documentation of disease terminus is complex, in part owing to circumstances where past communities experienced overlapping epidemics, such as leprosy and plague. For most settings, these syndemics-whereby there is an interaction between two or more epidemic diseases-both exacerbate and enhance the burden of morbidity in a community or region. Fundamental to understanding the severity and duration of epidemics is the consideration of multiple factors that simultaneously influence the severity and duration of the specific infectious diseases in a community or region, including poor oral health, under-nutrition, iron deficiency anemia, and elevated parasite load. In our view, comprehending the beginning, the middle, and the end of epidemics requires understanding the wider context of syndemics, the multiple challenging circumstances that undermine health and community stability, and how biosocial factors differentially affect the immune competence of individuals. This article provides several examples of the application of bioarchaeology and syndemics theory in achieving an understanding of how epidemics end. Pathogens continue to circulate, even after what appears to be the end. In effect, then, there is no "end," just evolution of opportunistic pathogens and our ability (or not) to mitigate them.

The transition from a human diet based exclusively on wild plants and animals to one involving dependence on domesticated plants and animals beginning 10,000 to 11,000 y ago in Southwest Asia set into motion a series of profound health, lifestyle, social, and economic changes affecting human populations throughout most of the world. However, the social, cultural, behavioral, and other factors surrounding health and lifestyle associated with the foraging-to-farming transition are vague, owing to an incomplete or poorly understood contextual archaeological record of living conditions. Bioarchaeological investigation of the extraordinary record of human remains and their context fromNeolithic Çatalhöyük (7100-5950 cal BCE), a massive archaeological site in south-central Anatolia (Turkey), provides important perspectives on population dynamics, health outcomes, behavioral adaptations, interpersonal conflict, and a record of community resilience over the life of this single early farming settlement having the attributes of a protocity. Study of Çatalhöyük human biology reveals increasing costs to members of the settlement, including elevated exposure to disease and labor demands in response to community dependence on and production of domesticated plant carbohydrates, growing population size and density fueled by elevated fertility, and increasing stresses due to heightened workload and greater mobility required for caprine herding and other resource acquisition activities over the nearly 12 centuries of settlement occupation. These changes in life conditions foreshadow developments that would take place worldwide over the millennia following the abandonment of Neolithic Çatalhöyük, including health challenges, adaptive patterns, physical activity, and emerging social behaviors involving interpersonal violence.

Numerous bioarchaeological studies emphasize an increase in dental lesions associated with the transition to agricultural subsistence. Over the years, this diachronic trend has led to the conflation and oversimplification of specific dental indicators of oral health with broad subsistence strategies, emphasizing intergroup variation at the expense of intragroup variation. In order to explore such hidden variation, this metastudy uses published data from 185 archaeological sites to test the hypothesis that the prevalence of dental lesions (carious lesions, antemortem tooth loss, and periapical abscesses) among classified agricultural groups is higher than among hunter-gatherers. As a secondary hypothesis, this study also tests the association between climatic variables (temperature variation, altitude, and precipitation) and dental lesion prevalence. Our results show that, despite significant differences in the average prevalence of carious lesions between agricultural and hunter-gatherer populations, the variation in caries prevalence shows high overlap (>70%) between subsistence patterns. Additionally, differences in the prevalence of antemortem tooth loss and periapical abscesses between agricultural and hunter-gatherer populations are not significant, showing even larger overlaps in prevalence ranges. Complementing the lifestyle analyses, climatic factors (mean temperature, annual temperature, and precipitation) are significantly correlated with the prevalence of specific dental pathological lesions and not others. Our results emphasize the need to reevaluate certain dental conditions as direct indicators of broad subsistence patterns, calling attention to the complex multifactorial pathogenesis of dental lesions and the nonlinear relationship between oral indicators of health and subsistence lifeways.

Objectives: The transition from foraging to farming is usually associated with unprecedented population densities coupled with an increase in fertility and population growth. However, little is known about the biological effects of such demographic changes during the Neolithic. In the present work, we test the relationship between diachronic changes in population size, relative exposure to developmental stressors, and patterns of dental fluctuating asymmetry in the Neolithic population of Çatalhöyük (Turkey, 7,100–5,950 cal BC). Materials and Methods: We calculate fluctuating asymmetry of mesio‐distal and bucco‐lingual diameters of upper and lower permanent canines and first and second molars on a large (N = 259) sample representing adults of both sexes and various age classes. Results: Results show only a moderate decrease of fluctuating asymmetry during the late phase of occupation of the site, possibly linked to a decrease in population density, and no differences in asymmetry between sexes. Discussion: Though preliminary, our data reflect the presence of developmental stressors throughout the occupation of the site, albeit with a slight improvement in living conditions during the latest periods of occupation. At the same time, these data confirm the key role of diet as buffer against the detrimental effects of fluctuating demographic pressures on the biology of prehistoric human populations.

Beginning some 10,000 years ago, humans began a dramatic alteration in living conditions relating especially to the shift in lifeway from foraging to farming. In addition to the initiation of and increasing focus on the production and consumption of domesticated plant carbohydrates, this revolutionary transformation in diet occasioned a decline in mobility and an increased size and agglomeration of populations in semipermanent or permanent settlements. These changes in life conditions presented an opportunity for increased transmission of pathogenic microbes from host to host, such as those that cause major health threats affecting most of the 7.5 billion members of our species today. This article discusses the bioarchaeology of infectious disease, focusing on tuberculosis, treponematosis, dental caries, and periodontitis, all of which continue to contribute to high levels of morbidity and mortality among the world's populations today.

Long-distance exchange of copper objects during the Archaic Period (ca. 8000-3000 cal B.P.) is a bellwether of emergent social complexity in the Eastern Woodlands. Originating from the Great Lakes, the Canadian Maritimes, and the Appalachian Mountains, Archaic-age copper is found in significant amounts as far south as Tennessee and in isolated pockets at major trade centers in Louisiana but is absent from most of the southeastern United States. Here we report the discovery of a copper band found with the cremated remains of at least seven individuals buried in the direct center of a Late Archaic shell ring located in coastal Georgia. Late Archaic shell rings are massive circular middens thought to be constructed, in part, during large-scale ritual gatherings and feasting events. The exotic copper and cremated remains are unique in coastal South Carolina and Georgia where Archaic-age cremations are conspicuously absent and no other Archaic copper objects have been reported. Elemental data produced through laser ablation inductively coupled plasma mass spectrometry shows the copper originated from the Great Lakes, effectively extending Archaic copper exchange almost 1,000 km beyond its traditional boundaries. Similarities in mortuary practices and the presence of copper originating from the Great Lakes reveal the presence of long-distance exchange relations spanning vast portions of the eastern United States and suggest an unexpected level of societal complexity at shell ring localities. These findings are consistent with the hypothesis that elite actors solidified their positions through ritual gatherings and the long-distance exchange of exotic objects during the Archaic.

Food has long served as a mechanism for identifying and reinforcing social structures, but while carbon and nitrogen isotope analysis has provided important identity-based evidence of past diets, the cyclical and stable/fluid nature of food consumption practices across the life course has been relatively neglected. In this paper, the large human assemblage at Çatalhöyük with all age groups present has enabled diet reconstruction of the rarely represented groups of older children and adolescents as well as for the young, middle and old adult age groups of both sexes. These data show how neonates reflect foods available to pregnant mothers, that infants were breastfed until around 18 months of age and weaned by three years of age, older children had a different diet compared to adolescents and young adults who, in turn, differed from middle and older adults. The absence of sex-related differences suggests changes in food consumed at Çatalhöyük accompanied the marking of transitions through the life course. [ABSTRACT FROM AUTHOR]

The bioarchaeological record of human remains viewed in the context of ecology, subsistence, and living circumstances provides a fundamental source for documenting and interpreting the impact of plant and animal domestication in the late Pleistocene and early to middle Holocene. For Western Asia, Çatalhöyük (7100-5950 cal BC) in central Anatolia, presents a comprehensive and contextualized setting for interpreting living circumstances in this highly dynamic period of human history. This article provides an overview of the bioarchaeology of Çatalhöyük in order to characterize patterns of life conditions at the community level, addressing the question, What were the implications of domestication and agricultural intensification, increasing sedentism, and population growth for health and lifestyle in this early farming community? This study employs demography, biogeochemistry, biodistance analysis, biomechanics, growth and development, and paleopathology in order to identify and interpret spatial and temporal patterns of health and lifestyle under circumstances of rapid population growth and aggregation and changing patterns of acquiring food and other resources. The record suggests that the rapid growth in population size was fueled by increased fertility and birthrate. Although the household was likely the focus of economic activity, our analysis suggests that individuals interred in houses were not necessarily biologically related. Predictably, the community employed resource extraction practices involving increased mobility. Although oral and skeletal indicators suggest some evidence of compromised health (e.g. elevated subadult infection, dental caries), growth and development of juveniles and adult body size and stature indicate adjustments to local circumstances.

ABSTRACT Adult stature variation is commonly attributed to differential stress-levels during development. However, due to selective mortality and heterogeneous frailty, a population's tall stature may be more indicative of high selective pressures than of positive life conditions. This article examines stature in a biocultural context and draws parallels between bioarchaeological and living populations to explore the multidimensionality of stature variation in the past. This study investigates: 1) stature differences between archaeological populations exposed to low or high stress (inferred from skeletal indicators); 2) similarities in growth retardation patterns between archaeological and living groups; and 3) the apportionment of variance in growth outcomes at the regional level in archaeological and living populations. Anatomical stature estimates were examined in relation to skeletal stress indicators (cribra orbitalia, porotic hyperostosis, linear enamel hypoplasia) in two medieval bioarchaeological populations. Stature and biocultural information were gathered for comparative living samples from South America. Results indicate 1) significant ( P < 0.01) differences in stature between groups exposed to different levels of skeletal stress; 2) greater prevalence of stunting among living groups, with similar patterns in socially stratified archaeological and modern groups; and 3) a degree of regional variance in growth outcomes consistent with that observed for highly selected traits. The relationship between early stress and growth is confounded by several factors-including catch-up growth, cultural buffering, and social inequality. The interpretations of early life conditions based on the relationship between stress and stature should be advanced with caution.

ABSTRACT The peopling, origins, and early prehistory of the Americas are topics of intense debate. However, few studies have used human remains to document and interpret patterns of health and lifestyle of Paleoamericans. This study provides the first investigation to characterize oral health in a series of early Holocene skeletal remains from Lagoa Santa, Brazil, a locality containing the remains of some of the earliest inhabitants of South America (10,000-7,000 BP). The sample is composed of 949 teeth and 1925 alveoli from an estimated 113 individuals excavated from 17 archaeological sites located in the State of Minas Gerais. We compare dental caries and abscess prevalence at Lagoa Santa to a large sample of human skeletons from the Western Hemisphere Project (WHP) database using both individual and tooth/alveolus count methods. In addition, antemortem tooth loss and tooth wear were analyzed in Lagoa Santa by sex and age. The results show that Lagoa Santa dental caries and abscess prevalence are significantly higher than observed among other hunter-gatherers included in the WHP database, except when abscess prevalence is considered by individual count. Adult females have less tooth wear coupled with higher prevalence of dental caries and antemortem tooth loss than adult males. These results point to an unexpected record of poor oral health at Lagoa Santa, especially among females. A diet based on a highly cariogenic combination of wild tubers and fruits is suggested as an explanation for the elevated rate, characterizing an early adaptation to a tropical environment in South America.
