Nutrition and health at contact in late prehistoric central Gulf Coast Florida

This paper presents an analysis of human remains from Tatham Mound, a dual-component mortuary site from central Gulf Coast Florida. The human remains from Tatham are significant because they come from a limited time period during the initial contact with Europeans at AD 1525-1550. Dietary reconstruction demonstrates that at the time of European contact, maize was not a predominant dietary item. Low frequencies for several dental and skeletal pathological indicators are consistent with relatively good health as compared to other Southeastern late prehistoric and protohistoric populations. Despite the limited time period represented by the mound population, critical interactions occurred between Native Americans and Spaniards, as indicated by skeletal elements severed by metal weapons. The Tatham population is significant because it is one of the earliest studied populations contacted by Europeans in North America, and the only one with well-documented sharp-force trauma that represents intergroup hostility.     

Traumatic events and life-style in ancient Italian populations

Traumatic lesions are commonly found in archaeological skeletal samples and provide useful information about various behavioral and cultural aspects of the populations. Our aim was to evaluate the relationship between the distribution and types of skeletal traumatic lesions and the different life-styles of past populations. We examined three necropolises in central Italy. Pozzilli (VI-IV century BC) and Quadrella (I-IV century AD) are from the same geographical area (Molise) but belong to different periods; Novilara (IX-VI century BC) is located in Marche but belongs to the Iron Age like Pozzilli. The lesions observed at Pozzilli seem not to be accidental, whereas the traumas observed at Quadrella can be attributed to occasional, unintentional events. Cranial injuries observed at Novilara strengthen the hypothesis that the population was composed, at least in part, of warriors. Our results suggest the presence of a relationship between skeletal traumatic lesions and life-styles of populations.     

Analysis of human skeletal remains from Nadin iron age burial mound

This analysis attempts to reconstruct health, disease and life conditions of the population buried in Nadin, a burial mound, situated in central Dalmatia, Croatia. The analyzed skeletal material belongs to Liburnian culture and could be dated to early Iron Age, from 9th to 6th century B.C. The sample consists of a minimum number of 37 individuals, 7 children and 30 adults. The frequency of all the observed conditions is relatively low. Cribra orbitalia was observed only in females, the frequency of periosteal reaction on the tibiae is 26.1%. Two cases of cranial trauma were observed. Analyzed teeth exhibit low prevalence of carious lesions, ante mortem tooth loss and linear enamel hypoplasia. The case of hyperostosis frontalis interna on the endocranial surface of the frontal bone was observed. The affected skull belongs to the older adult female.     

Tuberculosis and leprosy in Italy. New skeletal evidence

Tuberculosis (TB) and leprosy are infections caused by Mycobacteria. This paper documents new skeletal evidence in Italy from the Iron Age site of Corvaro (Central Italy; 5th century BCE) and the Roman site of Palombara (Central Italy; 4th–5th century CE), and briefly reviews the extant evidence for these infections in Italy. The skeletal evidence for TB in Italy is more ancient than for leprosy, and is more common. The oldest evidence for both mycobacterial diseases is in the North of Italy, but this could be by chance, even if biomolecular models suggest a land route from the East to central Europe, especially for leprosy.     

Changes in skeletal robusticity in an iron age agropastoral group: The samnites from the Alfedena necropolis (Abruzzo,Central Italy)

Cross‐sectional geometrical (CSG) properties of an Iron Age Samnite group from the Alfedena necropolis (Abruzzo, Italy, 2600–2400 B.P.) are compared with a Ligurian Neolithic sample (6000–5500 B.P.). In the period under examination, Samnites were organized in a tribal confederation led by patrilinear aristocracies, indicating incipient social stratification. In comparison, Neolithic society lacked clear signs of social hierarchy. The subsistence of both groups was mainly based on pastoralism and agriculture, but changes in habitual behavior are expected due to the socio‐economic transformations that characterized the Iron Age. The Samnites' warlike ideology suggests that unimanual weapon‐use and training would have become frequent for males. The intensification of agriculture and the adoption of transhumant pastoralism, performed by a smaller subset of the population, likely led to a lower average level of logistic mobility. The strongly genderized ideology of the period suggests a strict sexual division of labor, with women primarily performing sedentary tasks. CSG properties based on periosteal contours were calculated for humeri, femora, and tibiae (N = 61). Results corroborated the expectations: Alfedena males show substantial humeral bilateral asymmetry, indicating prevalent use of one arm, likely due to weapon training. In both sexes lower limb results indicate reduced mobility with respect to the Neolithic group. Sexual dimorphism is significant in both humeral asymmetry and lower limb indicators of mobility. Although both groups could be broadly defined as agropastoral based on archeological and historical evidence, CSG analysis confirmed important differences in habitual behavior.

Possible relationship of cranial traumatic injuries with violence in the south‐east Iberian Peninsula from the Neolithic to the Bronze Age

The main aim of this study was to analyze the presence and distribution of cranial trauma, as possible evidence of violence, in remains from the Neolithic to Bronze Age from the SE Iberian Peninsula. The sample contains skulls, crania, and cranial vaults belonging to 410 prehistoric individuals. We also studied 267 crania from medieval and modern times for comparative purposes. All lesions in the prehistoric crania are healed and none of them can be attributed to a specific weapon. In all studied populations, injuries were more frequent in adults than in subadults and also in males than in females, denoting a sexual division in the risk of suffering accidents or intentional violence. According to the archeological record, the development of societies in the SE Iberian Peninsula during these periods must have entailed an increase in conflict. However, a high frequency of cranial traumatic injuries was observed in the Neolithic series, theoretically a less conflictive time, and the lowest frequency was in crania from the 3rd millennium B.C. (Copper Age), which is characterized by the archeologists as a period of increasing violence. The relatively large size and the high rate of injuries in Neolithic crania and the practice of cannibalism are strongly suggestive of episodes of interpersonal or intergroup conflict. The number and distribution of injuries in Bronze Age is consistent with the increase in violence at that time described by most archeologists.

Familial segregation in the iron age community of Alfedena, Abruzzo, Italy, based on osteodental trait analysis

Numerous authors have studied human cemetery remains with an eye toward identifying different socially stratified ethnic or kinship groups within the same population. The interments of the protohistoric graveyard of Alfedena, Abruzzo, Italy, show recurrent organization in separate structures, suggesting to several involved archaeologists that these structures express family groups and/or differences in social function of the occupants. This has induced us to analyze the possible biological implications of specific models for kinship groups, lineages, or mating forms in graveyards. One hundred ninety-six metric and nonmetric skeletal and dental variables were collected. The analysis of metric features was performed by analysis of variance and by calculating divergences between each pair of individuals. The position parameters of the inter-and intragroup distance distributions were then compared by means of nonparametric tests. The nonmetric features were analyzed by contingency tables. The partition of intercircle variance is twice as frequently significant for males (20 variables) as for females (10). For metric variables in males, 20.9% displayed a probability level less than 5% for the null hypothesis of random distribution of individuals in the circles. Fewer (10.3%, but still more than expected at random) reached this level of significance for the females. In the male groups, 19% of nonmetric features showed significant frequency differences, but this was true in only 4.3% of the females.(ABSTRACT TRUNCATED AT 250 WORDS)     

Stature in archeological samples from central Italy: methodological issues and diachronic changes

Stature reconstructions from skeletal remains are usually obtained through regression equations based on the relationship between height and limb bone length. Different equations have been employed to reconstruct stature in skeletal samples, but this is the first study to provide a systematic analysis of the reliability of the different methods for Italian historical samples. Aims of this article are: 1) to analyze the reliability of different regression methods to estimate stature for populations living in Central Italy from the Iron Age to Medieval times; 2) to search for trends in stature over this time period by applying the most reliable regression method. Long bone measurements were collected from 1,021 individuals (560 males, 461 females), from 66 archeological sites for males and 54 for females. Three time periods were identified: Iron Age, Roman period, and Medieval period. To determine the most appropriate equation to reconstruct stature the Delta parameter of Gini (Memorie di metodologia statistica. Milano: Giuffre A. 1939), in which stature estimates derived from different limb bones are compared, was employed. The equations proposed by Pearson (Philos Trans R Soc London 192 (1899) 169-244) and Trotter and Gleser for Afro-Americans (Am J Phys Anthropol 10 (1952) 463-514; Am J Phys Anthropol 47 (1977) 355-356) provided the most consistent estimates when applied to our sample. We then used the equation by Pearson for further analyses. Results indicate a reduction in stature in the transition from the Iron Age to the Roman period, and a subsequent increase in the transition from the Roman period to the Medieval period. Changes of limb lengths over time were more pronounced in the distal than in the proximal elements in both limbs.     

Trauma and violence in the Wari empire of the Peruvian Andes: warfare, raids, and ritual fights

This study examines bioarchaeological evidence for violence during the period of Wari imperialism in the Peruvian Andes through analysis of skeletal trauma from three populations dating to AD 650-800. The samples are from contemporaneous archaeological sites: Conchopata, a Wari heartland site in central highland Peru; Beringa, a community of commoners in the Majes valley of the southern Wari hinterland; and La Real, a high status mortuary site, also in the Majes valley. Given the expansionist nature of Wari and its military-related iconography and weaponry, it is hypothesized that Wari imperialism was concomitant with greater levels of violence relative to other prehispanic groups in the Andes. It is also hypothesized that differential articulation with the Wari empire (e.g., heartland vs. hinterland groups) affected the frequency and patterning of trauma. Results show that cranial trauma frequency of the three Wari era samples is significantly greater than several other Andean skeletal populations. This suggests that Wari rule was associated with high levels of violence, though it may not have always been related to militarism. The three adult samples show similar frequencies of cranial trauma (Conchopata = 26%; Beringa = 33%; La Real = 31%). This may suggest that differential positioning in the Wari empire had little effect on exposure to violence. Sex-based differences in cranial trauma frequencies are present only at La Real, but wound patterning differs between the sexes: females display more wounds on the posterior of the cranium, while males show more on the anterior. These data suggest that Wari rule may have contributed to violence.     

Iron Age breastfeeding practices in Britain: isotopic evidence from Wetwang Slack, East Yorkshire

We present here the results of carbon and nitrogen isotopic analysis of bone collagen undertaken on all skeletal remains of infants and young children below the age of 6 years (n = 34) from the internationally important British cemetery site at Wetwang Slack in East Yorkshire (middle Iron Age, ca. 4th to 2nd centuries BC). The aim of the study is to investigate infant diet, with particular reference to breastfeeding and weaning practices, and to compare the data with previously published studies of archaeological populations, particularly in the context of the variation in data patterns to be seen between sites. The skeletal remains from Wetwang Slack form the only prehistoric collection in the UK, prior to the Romano-British period, with sufficient individuals in this age group to make such an isotopic study viable alongside associated adults and older children. The data are compared in detail with published data from two other sites, one from 19th century Canada and the other from Medieval Britain. The results suggest an unusual situation at Wetwang Slack, with neither the nitrogen nor the carbon isotope ratios conforming to expectations when compared with the putative mothers. We discuss how these data compare with the expectation for breastfed infants and we interpret the divergence in this case to be due to restricted breastfeeding and the early introduction of supplementary foods.     

Regional, social, and evolutionary perspectives on treponemal infection in the Southeastern United States

The origin and geographic distribution of syphilis, a form of treponemal infection, have long been regarded as among the most important medical riddles of prehistoric and historic disease evolution. In this study, we expand on previous discussions of the origin, evolution, and relationship of treponemal infections as they occur in the prehistoric southeastern United States. Individuals from 25 skeletal series (n = 2,410 individuals) were examined for cranial and dental lesions characteristic of treponemal infection. They lived between the Archaic period (8000-1000 BC) and protohistoric period (AD 1500-1600), and in physiographic zones from the coast to the mountains of Alabama, Florida, North Carolina, and Tennessee. Radial cranial scars were found for 47 individuals, but none of the four cases of dental lesions could be attributed to congenital syphilis. Differences in frequency of cranial lesions by region were minimal, with the least number of cases found for the mountains, but the frequency of positive cases tended to increase through time. It is suggested that increasing population density and changing behaviors, rather than novel strains of the treponemal pathogen, are responsible for the chronological increase in the frequency of positive cases.     

The origin and antiquity of syphilis (treponematosis), in southeast Asia

The pausible reasons for the paucity of skeletal evidence regarding the contraversal issue on the origin and antiquity of treponematosis (syphilis) in southeast Asia, suggest a lack of thorough investigation into the skeletal biology of the several remains that were excavated. According to an estimate the skeletal remains of about 69.5 per cent (107) of the prehistoric sites were not reported and even the remaining 30.5 per cent were not thoroughly investigated for paleopathological aspects. The two recent studies of possible evidence of treponematosis during megalithic (Iron Age) period supports the Old World hypothesis that the disease was prevalent during pre-Columbian period in India.     

Continuity or discontinuity of the life-style in central Italy during the Roman Imperial Age-Early Middle Ages transition: diet, health, and behavior

Dento-alveolar pathologies and alterations (dental wear, caries, abscesses, ante mortem tooth loss (AMTL), calculus, hypoplastic defects, and chipping) and skeletal markers of health (cribra orbitalia and periostitis) were analyzed in two skeletal samples from the necropolises of Quadrella (I-IV c. AD) and Vicenne-Campochiaro (VII c. AD) in the Molise region of central Italy. The aim was to determine if the Roman Imperial Age-Early Middle Ages transition characterized by political, socioeconomic, and cultural transformations affected the biology of these populations, particularly their alimentation and health status. The frequencies of caries and AMTL, similar in the two samples, suggest a high consumption of carbohydrates. The higher levels of heavy wear, calculus, and interproximal chipping in the Vicenne population indicate a greater use of fibrous foods (both meat and others), in line with the dietary model of Germanic peoples. Health conditions do not appear to have been good in either period, as shown by the high frequencies of linear hypoplasia and the presence of cribra orbitalia and periostitis. The diet of the individuals buried with horses of the Vicenne population did not differ from that of the rest of the population, whereas there were evident differences in the use of the teeth for nonmasticatory activities among these individuals. Therefore, from the point of view of alimentation and health status, the profound socioeconomic and cultural transformations during the Late Antiquity-Early Middle Ages transition do not seem to have been translated into a true discontinuity of the two Molisan populations.     

Paleodemography of India and Ceylon since 3000 B.C

Biological and cultural adaptations of prehistoric man in South Asia are surveyed against the background of geological-climatic-biotic changes occurring within Pleistocene and post-Pleistocene times. The earliest human remains discovered thus far in the Indian sub-continent are skeletons associated with Late Stone Age (Mesolithic) cultural materials. These series and those associated with subsequent cultural horizons (Neolithic, Chalcolithic, Harappan, Iron Age and Early Historic) are reviewed in terms of their suitability for palaeodemographic study. In South Asia this kind of research is best approached through the analysis of local sites where skeletal material is available and where reconstruction of ancient ecological settings is feasible. Three cases are presented: (1) population displacement and mobility in the pre-Vedda and Vedda biological continuum in Ceylon; (2) influence of changing nutritional factors upon the pathology of jaws and teeth for the Late Stone Age skeletal series from Langhnaj; (3) causes of death at Mohenjo-daro, with a discussion of the undue emphasis in the anthropological literature upon trauma and neglect of significant attempts to discern causes of death where these are relevant to pathology and to specific ecological adaptations.     

Late Pleistocene human evolution in Sicily: comparative morphometric analysis of Grotta di San Teodoro craniofacial remains

The paleoanthropological remains from Grotta di San Teodoro near Acquedolci (province of Messina, Italy) represent the oldest and largest skeletal collection yet found documenting human settlement of Sicily. The sample, attributed to the Late Epigravettian (between 14,000 and 10,000 years B.P.), consists of seven variously complete adult individuals (San Teodoro 1–7). We compare the cranial sample to an array of both prehistoric and recent samples using multivariate techniques including D² distance analysis, canonical variate analysis, cluster analysis, and multidimensional scaling. Overall, the San Teodoro cranial sample displays a morphometric pattern close to Western European groups of similar antiquity, in particular those from Central and Southern Italy. The morphometric affinities indicate that these people probably came from peninsular Italy by sea during the Late Epigravettian epoch. An alternative hypothesis is that they descended from immigrants that arrived by land during a low sea level episode corresponding to the maximum Würmian regression, about 18,000 years B.P, with gene flow accounting for the morphological homogeneity with the populations of peninsular Italy. The San Teodoro skeletal sample provides the first reliable evidence for human settlement of Sicily.     

Genetic Continuity of Bronze Age Ancestry with Increased Steppe-Related Ancestry in Late Iron Age Uzbekistan

Although Uzbekistan and Central Asia are known for the well-studied Bronze Age civilization of the Bactria–Margiana Archaeological Complex (BMAC), the lesser-known Iron Age was also a dynamic period that resulted in increased interaction and admixture among different cultures from this region. To broaden our understanding of events that impacted the demography and population structure of this region, we generated 27 genome-wide single-nucleotide polymorphism capture data sets of Late Iron Age individuals around the Historical Kushan time period (∼2100–1500 BP) from three sites in South Uzbekistan. Overall, Bronze Age ancestry persists into the Iron Age in Uzbekistan, with no major replacements of populations with Steppe-related ancestry. However, these individuals suggest diverse ancestries related to Iranian farmers, Anatolian farmers, and Steppe herders, with a small amount of West European Hunter Gatherer, East Asian, and South Asian Hunter Gatherer ancestry as well. Genetic affinity toward the Late Bronze Age Steppe herders and a higher Steppe-related ancestry than that found in BMAC populations suggest an increased mobility and interaction of individuals from the Northern Steppe in a Southward direction. In addition, a decrease of Iranian and an increase of Anatolian farmer-like ancestry in Uzbekistan Iron Age individuals were observed compared with the BMAC populations from Uzbekistan. Thus, despite continuity from the Bronze Age, increased admixture played a major role in the shift from the Bronze to the Iron Age in southern Uzbekistan. This mixed ancestry is also observed in other parts of the Steppe and Central Asia, suggesting more widespread admixture among local populations.     

Demography And Disease Patterns In A Protohistoric Plains Group: A Study ofthe Mobridge Site (39WW1)

Abstract

Epidemic disease has often been cited as the major factor causing historic depopulation of Native American groups. Because a range of infectious diseases introduced by Europeans struck different tribes at different times, the effects of these diseases or the outbreak of epidemics were not uniform for all groups. The Arikara of the American Plains wereamong the last North American Indian groups to experience direct contact with Europeans. However, indirect contact with introduced infectious diseases may have reduced these Plains protohistoric groups prior to established relations with Europeans. Historic depopulation of the Arikara and a demographic study of the skeletal remains from the Mobridge site (39WW1 l are the focus of this case study of the protohistoric population dynamics of a Native American group. Disease patterns are used in the demographic analysis to aid in the interpretation of observed mortality patterns. Evaluation of the skeletal remains from the Mobridge Site includes life table reconstruction and differential diagnosis of skeletal pathology complexes. Results of these analyses show that certain underlying disease processes evident skeletally correspond to deviations in the age distribution. Thus; the protohistoric mortality patterns of Mobridge appear to reflect the early stages of impact from introduced diseases.     

Dental enamel hypoplasias and health changes in the Middle Bronze Age - Early Iron Age transition at Pella in Jordan.

Dental enamel hypoplasias are increasingly being used in epidemiological studies as indicators of health within both modern and prehistoric populations. This symptom of growth disruption is used here to examine possible changes in health occurring at the transition between the Bronze Age and Iron Age in Jordan, through examination of enamel hypoplasias in skeletal remains from two tombs at the archaeological site of Pella. A small but not statistically significant difference in the prevalence and frequency of hypoplastic defects was found between the two time periods. These results suggest that the political and economic changes occurring at this time were not sufficiently stressful to cause a dramatic deterioration in health at the onset of the Early Iron Age.     

The Genetic Origin of Daunians and the Pan-Mediterranean Southern Italian Iron Age Context

The geographical location and shape of Apulia, a narrow land stretching out in the sea at the South of Italy, made this region a Mediterranean crossroads connecting Western Europe and the Balkans. Such movements culminated at the beginning of the Iron Age with the Iapygian civilization which consisted of three cultures: Peucetians, Messapians, and Daunians. Among them, the Daunians left a peculiar cultural heritage, with one-of-a-kind stelae and pottery, but, despite the extensive archaeological literature, their origin has been lost to time. In order to shed light on this and to provide a genetic picture of Iron Age Southern Italy, we collected and sequenced human remains from three archaeological sites geographically located in Northern Apulia (the area historically inhabited by Daunians) and radiocarbon dated between 1157 and 275 calBCE. We find that Iron Age Apulian samples are still distant from the genetic variability of modern-day Apulians, they show a degree of genetic heterogeneity comparable with the cosmopolitan Republican and Imperial Roman civilization, even though a few kilometers and centuries separate them, and they are well inserted into the Iron Age Pan-Mediterranean genetic landscape. Our study provides for the first time a window on the genetic make-up of pre-Roman Apulia, whose increasing connectivity within the Mediterranean landscape, would have contributed to laying the foundation for modern genetic variability. In this light, the genetic profile of Daunians may be compatible with an at least partial autochthonous origin, with plausible contributions from the Balkan peninsula.
