Este trabalho teve por objetivo principal estudar as relações sociais e simbólicas de gênero na pré-história brasileira, com base no estudo dos rituais funerários e remanescentes ósseos humanos de populações horticultoras do noroeste de Minas Gerais, que de 1540 anos a.C. a 1540 d.C. ocuparam de forma sazonal e constante a Gruta do Gentio II para a realização de seus rituais funerários. Nosso estudo foi dividido em duas partes, com base na análise de variáveis relacionadas ao ritual funerário (tratamento dado ao corpo, posição, orientação, direção da face, características da cova, distribuição temporal e espacial, acompanhamentos funerários) e aos remanescentes ósseos e dentários propriamente ditos (sexo, idade, fraturas, doenças, linhas de Harris, facetas suplementárias da tíbia, degeneração das superfícies articulares do esqueleto axial e apendicular, além de cáries, abrasão dentária, hipoplasia, doença periodontal, cálculos, abcessos dentários e perda ante-mortem). Dentro de uma perspectiva teórico-interpretativa simbólica, com base na arqueologia de gênero, pós-processualismo e arqueologia cognitiva, e nos métodos analíticos bioarqueológicos, acreditamos que foi possível compreender parte dos papéis sociais, desempenhados principalmente por homens e mulheres, além de adolescentes e crianças, no contexto arqueológico da Gruta do Gentio II, Unaí, Minas Gerais. / The aim of this work is to investigate the social and symbolic relations of gender in Brazilian prehistory, based on the study of human funerary rituals and bone remains of horticulturist populations in the northeast of Minas Gerais state who in a seasonal and constant form, in the period 1540 BC to 1540 AC, used the caverns at Gruta do Gentio II to perform their funerary rituals. Our study is divided in two parts based on the variables related to the funerary ritual (handling, position and orientation of the corpse, direction of the face, grave characteristics, distribution in space and time, grave goods) and to the bone and teeth remains respectively (sex, age, fractures, illnesses, Harris lines, supplementary tibia facets, joint surfaces degeneration of the axial and appendicular skeleton, and also caries, dental abrasion, hypoplasia, periodontal illness, calculus, dental abscesses and ante-mortem tooth loss). In a symbolic theoretical-interpretative perspective based on the gender archaeology, postprocessualism and cognitive archaeology, as well as the bioarchaeological analytic methods, we believe that it is possible to understand part of the social roles performed mainly by men and women but also by children and teenagers in the archaeological context of Gruta do Gentio II, Unaí, Minas Gerais.

abstract: Archaeologists have long contended that large-scale human migrations played an essential role in the cultural development of pre-Hispanic central Mexico. During the Epiclassic period (600-900 CE), migration is implicated in the appearance of new forms of material culture, sociopolitical disruptions, and the emergence of new regional polities. Sweeping social changes accompanied these developments, including demographic reorganization and increased levels of violence. Research across the social sciences finds that violence directed at individuals perceived as categorically distinct also typically increases during such periods of socio-political upheaval. This dissertation investigates identity-based violence in the Epiclassic Basin of Mexico to consider how diverse social identities contributed to the selection of victims of ritual violence. This research examines the skeletal remains from a sacrificial deposit at the Epiclassic shrine site of Non-Grid 4 in the Basin of Mexico, where a minimum of 180 human crania were interred as ritual offerings. The project reconstructs patterns of paleomobility and biological relatedness to determine whether individuals with distinct categorical social identities were more likely to become victims of human sacrifice. It answers the questions: (1) Were the sacrificed individuals predominantly locals who lived in the Basin of Mexico throughout their lives?; (2) Were the sacrificed individuals comprised of a single kin-group biologically continuous with pre-extant populations in the Basin of Mexico?; and (3) If victims were migrants biologically discontinuous with antecedent populations, from where in ancient Mesoamerica did they originate? Results indicate that a majority of sacrificial victims were immigrants originating north and south of the Basin of Mexico. Biogeochemical analyses of sacrificed individuals find that 80% are non-local migrants into the Basin, suggesting that they were likely targeted for violence based on their divergent residential histories. Multi-scalar biodistance analyses of Non-Grid 4 sacrificial victims demonstrate that they represent two biologically distinct groups. There was evidence, however, for both biological continuity among victims and pre-extant central Mexican populations, as well as for migration from northern and southern Mexico. This project therefore not only improves knowledge of migration during the central Mexican Epiclassic, but also contributes to broader anthropological understandings of the social context of violence. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2020

abstract: Bioarchaeologists often use dental data and spatial analysis of cemeteries to infer the biological and social structure of ancient communities. This approach is commonly referred to as biological distance (“biodistance”) analysis. While permanent crown data feature prominently in these efforts, few studies have verified the accuracy of biodistance methods for recognizing child relatives using deciduous teeth. Thus, as subadults comprise an essential demographic subset of mortuary assemblages, deciduous phenotypes may represent a critical but underutilized source of information on the underlying genetic structure of past populations. The goal of the dissertation is to​ quantitatively analyze the developmental program underlying deciduous phenotypes and​ to evaluate their performance in accurately reconstructing known genealogical relationships.​ This project quantifies morphological variation of deciduous and permanent tooth crowns from stone dental casts representing individuals of known pedigree deriving from three distinct populations: European Canadians, European Australians, and Aboriginal Australians. To address the paucity of deciduous-focused validation research, phenotypic distances generated from the dental data are subjected to performance analyses (biodistance simulations) and compared to genetic distances between individuals. While family-specific results vary, crown morphology performs moderately well in distinguishing relatives from non-relatives. Comparisons between deciduous and permanent results (i.e., Euclidean distances, Mantel tests, multidimensional scaling output) indicate that deciduous crown variation provides a more direct reflection of the underlying genetic structure of pedigreed samples. The morphology data are then analyzed within a quantitative genetic framework using maximum likelihood variance components analysis. Novel narrow-sense heritability and pleiotropy estimates are generated for the complete suite of deciduous and permanent crown characters, which facilitates comparisons between samples, traits, dentitions, arcades, antimeres, metameres, scoring standards, and dichotomization breakpoints. Results indicate wide-ranging but moderate heritability estimates for morphological traits, as well as low to moderate integration for characters within (deciduous-deciduous; permanent-permanent) and between (deciduous-permanent) dentitions. On average, deciduous and permanent homologues are more strongly genetically correlated than characters within the same tooth row. Results are interpreted with respect to dental development and biodistance methodology. Ultimately, the dissertation empirically validates the use of dental morphology as a proxy for underlying genetic information, including deciduous characters. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2017

This study tests whether musculoskeletal markers are attributable to occupational categories. It is hypothesized that individuals over the age of 30 years with a lifetime occupation as a laborer will demonstrate a significantly different pattern of activity markers from individuals in the white collar classifications. A sample of n=69 from the Maxwell Museum's Documented Skeletal Collection are investigated. Upper and lower extremities were scored for MSM type (robusticity, stress lesions, and ossification exostoses) and severity (grades 0 - 3) following Hawkey and Merbs (1995) visual reference system. To evaluate methodological approaches to MSM scoring, ossification exostoses and stress lesions were also scored using the Mariotti et al. (2004) proposed methods. Upper limb muscle insertion sites on the humerus, radius, and ulna and lower limb insertion sites on the femur, fibula, patella, calcaneus, and tibia were studied. The Kruskal Wallis test was used to predict occupational class according to an individual's aggregate MSM z-score. The Mann-Whitney test was used for comparison of aggregate MSM z-scores between the two occupational categories and for comparison of aggregate MSM z-scores between males and females. The Spearman correlation was used for non-parametric correlation analysis of aggregate MSM z-scores and the occupational categories of white collar and labor. The data were analyzed using the statistical software program SPSS (version 17.0). Results of this study show that musculoskeletal markers cannot statistically predict, nor can they be used to distinguish between, occupational categories of white collar and labor. Comparison of MSM shows no significant difference in the overall patterns of enthesopathies between individuals who report an occupation of white collar or those who report an occupation of laborer as defined by the U.S. Office of Personnel. Comparison of MSM in this population shows no significant difference between males and females, regardless of occupational category, a finding which runs counter to many earlier studies. Using dichotomous data it is revealed that laborers develop MSM symmetrically, evidence of whole-body activity. Further, white collar MSM can be associated with sitting and elevating the arm. Laborer's MSM are associated with lifting, twisting, pushing, squatting, walking, running and standing. Recommendations on methodology are provided.

This project employs a modified version of the Bioarchaeology of Care (BoC) in an analysis of Burial 1 from the Mississippi State Asylum, Jackson, MS. Burial 1 is a skeletal individual recovered from the historic MSA cemetery. Notably, Burial 1 exhibits recidivistic cranial trauma in the form of cranial depression fractures (CDFs) and significant entheseal changes in the upper extremities. However, because there is no identifying information associated with Burial 1, interpretations of the caretaking they may have received, both prior to and after institutionalization, include short- and long-term outcomes from their community and the MSA. Additionally, Burial 1’s CDFs and subsequent traumatic brain injury likely increased their risk of being institutionalized and created complications for them in the MSA. Despite the limitations of this study, future research applying a modified BoC could lead to otherwise unknown information about the lived experiences of institutionalized patients in historic institutions of care.

This research investigates maternal nutritional status through the analysis of young infants (N=27) that are likely pre-weaned from two Roman occupational periods at Put Dragulina. Because young infants are solely dependent on the nutritional status of their mother while in utero and postpartum through the consumption of breast milk, the presence of skeletal pathologies positively associated to nutritional deficiencies on the remains of young infants can be analyzed to reconstruct the nutritional status of the infant’s mother. This study finds that 89% (N=24) of young infants, regardless of occupational period, presented with skeletal pathologies consistent with nutritional deficiencies. These results suggest that the mothers who are absent from the Put Dragulina cemetery would have likely had poor nutritional statuses due to the high frequencies of nutritional stress indicators present on the skeletal remains of their infants.

This thesis reconstructs and analyzes a Classic period (AD 250-800) burial collection from the archaeological site of Loma Don Genaro in Oaxaca, Mexico. This research aims to address two main questions: 1.) What information about the burial collection is available through the archaeological archives? 2.) What does this information tell us about social organization during the Classic period at Loma Don Genaro? In order to address these questions, the following objectives were explored: to reconstruct ancient burials using archival material; to describe the burial demography across the site; to describe variation in grave goods; to relatively date and order the burials chronologically; to draw conclusions about social organization through patterns visible in the burial record. This project included bringing together existing archival records such as field drawings, burial record forms, lot forms, field maps, photographs, and field notes in order to reconstruct detailed burial records for 25 individuals. This recontextualization of the burial collection has made the data concerning each burial easily accessible, enabling further data to be gleaned from the remains. After creating a usable data management system for the burial collection and its associated records, the burials were analyzed. Analysis included: providing relative dates for the burials and chronologically ordering the burials using stratigraphic information; demographic analysis in order to identify the number adults, juveniles, males, and females in the collection, as well as the ages of each individual; analysis of burial position and orientation; analysis of the diversity of both the amount and type of grave goods (such as ceramic vessels, jade beads, figurines, and lithics) present in each burial. Several patterns relating to sex, age, and social status across the site were identified: there is an emphasis on adult burials with minimal children in the burial collection; the more elaborate burials reflecting a higher social status for the buried individuals were those with greater than ten ceramic vessels, had slab-lined burials, or were slab-lined and contained greater than ten vessels, and contained both male and female individuals. The data from this thesis provide an important snapshot of life during a key period of social change in ancient Mexico.

Although stable isotope analysis is routinely utilized in bioarchaeology and relies on principles that are well-understood, there are still fundamental issues that have not been thoroughly investigated. This thesis examines the relationship between inter-tissue spacing of carbon stable isotope values (δ13C) and age in juvenile human remains. Analyses of tissues within the same individual reveal disparate isotopic values for a variety of physiological and biological reasons discussed herein. This project examines the distance between the δ13C values in bone collagen, skin, hair, and nail, and examines how these distances vary between different age groups, utilizing data collected from 52 well-preserved human remains from the Dakhleh Oasis, Egypt: 28 individuals between the ages of 1 and 4 years, 14 between 5 and 10 years, and 10 between the ages of 11-15 years. The mean carbon isotope values for each tissue were compared across each age group, and used to calculate the differences between each tissue type. Although distances between tissues were found to vary across all age categories, the distances between collagen and hair, collagen and skin, and collagen and nail are all substantially greater in the 11-15 year old category than those in the 1-4 and 5-10 year categories. Possible physiological, developmental and social factors are discussed in an effort to explain this discrepancy
