Changes In Male Hunting Returns, Raymond B. Hames

Department of Anthropology: Faculty Publications

Research on changes in male hunting among hunter-gatherers addresses two important issues in early human evolution: the nature of the family and trade-offs in mating and parenting effort as well as the development of embodied capital. In the hunter-gatherer literature, there is a debate about the function of male hunting that has implications for understanding the role males play in the evolution of the pair bond. The traditional model argues that male hunting and other economic activities are forms of male provisioning or parenting effort designed to enhance a man’s fitness through his wife’s reproduction and the survivorship of their …

A Characterization Of Human Burial Signatures Using Spectroscopy And Lidar, Katie Ann Corcoran

Doctoral Dissertations

This study is an analysis of terrestrial remote sensing data sets collected at the University of Tennessee’s Anthropology Research Facility (ARF). The objective is to characterize human burial signatures using spectroscopy and laser scanning technologies. The development of remote human burial detection methodologies depends on basic research to establish signatures that inform forensic investigations. This dissertation provides recommendations for future research on remote sensing of human burials, and for investigators who wish to apply these technologies to case work.

Data used in this study include terrestrial spectra, aerial hyperspectral imagery, satellite multispectral imagery, terrestrial light detection and ranging (LIDAR), and …

Understanding Population-Specific Age Estimation Using Multivariate Cumulative Probit Regression For Asian Skeletal Samples, Ji Eun Kim

Doctoral Dissertations

For many years, the field of anthropology has encouraged anthropologists to assume that population variation exists in skeletal aging although interpretations of population specificity in skeletal aging have been inconsistent. This project investigates age progressive changes in modern East and Southeast Asian populations, and attempts to quantify the magnitude of differences or similarities in skeletal aging between different Asian groups as a first step to develop a more inclusive age estimation method for Asian populations. Specifically, this study explores the utility of currently available age estimation methods for Asian populations, asks whether a population-specific aging method should be region-specific (Thai …

Three-Dimensional Analysis Of The Development Of Upper Arm Musculoskeletal Stress Markers In Late Adolescents And Young Adults Of Archaic And Mississippian Populations Of Tennessee, Heather Marie Guzik

Master's Theses

This study compares three methods for the evaluation of morphology of musculoskeletal attachment sites. Two methods were macroscopic and the third was microscopic, utilizing three-dimensional laser scanning and fractal analysis The morphology of 19 upper limb attachment sites was observed in 33 males aged 15 and 30+ years, dating to the Archaic and Mississippian periods from the southeastern U.S. It was hypothesized that 1) the microscopic method would identify subtler differences than the macroscopic methods; 2) enthesis development would be greater in the Mississippian population due to the increased subsistence workload, even among younger individuals; and 3) late adolescents would …

A Morphometric Examination Of Cranial Vault Modification In The Middle Cumberland Region Of Central Tennessee, Gregory James Wehrman

Masters Theses

Cranial vault modification (CVM) is a physical manifestation of intersections between culture and biology. Cultural practices that apply pressure to the head during infancy result in significant reshaping of the skull and can be either intentional or unintentional. Occipital flattening is present among many Mississippian skeletal samples from the Middle Cumberland Region (MCR) of central Tennessee and is thought to be an unintentional result of childcare practices. Traditional methods for CVM classification have concentrated on visual assessment of location and means of flattening; however, this method is subjective. This thesis seeks to evaluate visual assessment of CVM through a morphometric …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The goal of this study is to use the improved imaging capability of cone-beam computerized tomography (CBCT) to investigate the development and sexual dimorphism of the frontal sinus and surrounding supraorbital region in the subadult population of urban Southern Nevada. CBCT radiographs were obtained from the UNLV School of Dental Medicine archival dental records. Five hundred and fifty six of these radiographs were reviewed for the study. Two hundred and sixteen patients (92 males, 124 females) between the ages of 7 and 20 years were included based on inclusion/exclusion criteria. Samples were categorized into 3 subadult age groups for analysis: …

Detecting Evidence Of Systemic Inflammation From Osteological Markers In The Indian Knoll Population Of Ohio County, Kentucky., Krysta Wilham

Electronic Theses and Dissertations

Indian Knoll is an Archaic shell midden site located in the Green River region of west-central Kentucky, and was excavated twice in the first half of the 20^th century. While Indian Knoll has been the subject of frequent bioarchaeological studies, the present study presents an osteological analysis of the relationships between skeletal markers commonly associated with local inflammatory processes, and that have the potential to be used as proxies for systemic inflammation. The analysis revealed a significant positive association in the presence of periodontal disease (PD) and periosteal lesions (PL), suggesting a potential underlying hyper-inflammatory status or phenotype. These …

Growth References For Tsimane Forager-Horticulturalists Of The Bolivian Amazon, Aaron D. Blackwell, Samuel S. Urlacher, Bret Beheim, Christopher Von Rueden, Adrian V. Jaeggi, Jonathan Stieglitz, Benjamin C. Trumble, Michael Gurven, Hillard Kaplan

ESI Publications

Objectives—Growth standards and references currently used to assess population and individual health are derived primarily from urban populations, including few individuals from indigenous or subsistence groups. Given environmental and genetic differences, growth may vary in these populations. Thus, there is a need to assess whether international standards are appropriate for all populations, and to produce population specific references if growth differs. Here we present and assess growth references for the Tsimane, an indigenous population of Bolivian forager-horticulturalists.

Methods—Mixed cross-sectional/longitudinal anthropometrics (9,614 individuals; 30,118 observations; ages 0–29 years) were used to generate centile curves and Lambda-Mu-Sigma (LMS) tables for …

Salivary Microbiomes Of Indigenous Tsimane Mothers And Infants Are Distinct Despite Frequent Premastication, Cliff S. Han, Melanie Ann Martin, Armand E.K. Dichosa, Ashlynn R. Daughton, Seth Frietze, Hillard Kaplan, Michael D. Gurven, Joe Alcock

ESI Publications

Background. Premastication, the transfer of pre-chewed food, is a common infant and young child feeding practice among the Tsimane, forager-horticulturalists living in the Bolivian Amazon. Research conducted primarily with Western populations has shown that infants harbor distinct oral microbiota from their mothers. Premastication, which is less common in these populations, may influence the colonization and maturation of infant oral microbiota, including via transmission of oral pathogens. We collected premasticated food and saliva samples from Tsimane mothers and infants (9-24 months of age) to test for evidence of bacterial transmission in premasticated foods and overlap in maternal and infant salivary …

Egyptian Mummy Ct Scan Analysis And A Comparison Of Midwest Museum Practices For The Grand Rapids Public Museum, M. Kate Peterson

Anthropology Master's Theses

To meet the partial requirements for a Master of Arts degree in Anthropology from Western Michigan University, the following internship was completed between June 2015 and September 2016. A Computed Tomography (CT) scan analysis was conducted on the Grand Rapids Public Museum’s mummy, Nakhte-Bastet-Iru. This analysis was a collaborative effort by myself and medical and museum professionals. Insight into the mummy’s life and culture was uncovered through examination and analysis of paleoradiological views of her remains. Additional research into the practices of other Midwest museums provided valuable knowledge of current trends in the dissemination and exhibition of mummy CT scan …

This exceptional undertaking was the first complete scientific analysis of human remains from a Cambodian mass gravesite. Second, the author’s independent research at Choeung Ek and a collaborative project at another mass gravesite will be reviewed. The author’s research focuses on the traumatic injuries and demographics of the remains at Choeung Ek, while also incorporating cultural …

Cardiovascular Disease And Type 2 Diabetes In Evolutionary Perspective: A Critical Role For Helminths?, Michael D. Gurven, Benjamin C. Trumble, Jonathan Stieglitz, Aaron D. Blackwell, David E. Michalik, Caleb E. Finch, Hillard Kaplan

ESI Publications

Heart disease and type 2 diabetes are commonly believed to be rare among contemporary subsistencelevel human populations, and by extension prehistoric populations. Although some caveats remain, evidence shows these diseases to be unusual among well-studied hunter-gatherers and other subsistence populations with minimal access to healthcare. Here we expand on a relatively new proposal for why these and other populations may not show major signs of these diseases. Chronic infections, especially helminths, may offer protection against heart disease and diabetes through direct and indirect pathways. As part of a strategy to insure their own survival and reproduction, helminths exert multiple cardio-protective …

Paleoepidemiological Analysis Of Trauma In A Roman Period Population From Kellis, Egypt, Circa 50-450 Ad, Isabella A. Graham

Electronic Thesis and Dissertation Repository

This thesis analyzes human skeletal trauma in a large well-preserved sample (n =268) from the Roman period Kellis site in the Dakhleh Oasis, Egypt. Prevalence was determined for both infracranial and cranial skeletal trauma. The null hypothesis tested was that there are no differences in trauma when stratified by sex and by age cohorts (i.e., 18-35, 36-50 and 51+). Despite the overall trauma prevalence being similar between the sexes when not differentiated by age, the null hypothesis was rejected. Key differences that occurred between the sexes were that males suffered greater malintent and occupational traumas, whereas osteoporosis was the major …

An Epigenetic Clock Analysis Of Race/Ethnicity, Sex, And Coronary Heart Disease, Steve Horvath, Michael Gurven, Morgan E. Levine, Benjamin C. Trumble, Hillard Kaplan, Hooman Allayee, Beate R. Ritz, Brian Chen, Ake T. Lu, Tammy M. Rickabaugh, Beth D. Jamieson, Dianjianyi Sun, Shengxu Li, Wei Chen, Lluis Quintana-Murci, Maud Fagny, Michael S. Kobor, Philip S. Tsao, Alexander P. Reiner, Kerstin L. Edlefsen, Devin Absher, Themistocles L. Assimes

ESI Publications

Background: Epigenetic biomarkers of aging (the “epigenetic clock”) have the potential to address puzzling findings surrounding mortality rates and incidence of cardio-metabolic disease such as: (1) women consistently exhibiting lower mortality than men despite having higher levels of morbidity; (2) racial/ethnic groups having different mortality rates even after adjusting for socioeconomic differences; (3) the black/white mortality cross-over effect in late adulthood; and (4) Hispanics in the United States having a longer life expectancy than Caucasians despite having a higher burden of traditional cardio-metabolic risk factors.

Results: We analyzed blood, saliva, and brain samples from seven different racial/ethnic groups. …

Modeling Prehistoric Health In The Middle Cumberland Region Of Tennessee: Mississippian Populations On The Threshold Of Collapse, Christina Laiz Fojas

Doctoral Dissertations

This research explores differences in mortality and survivorship resulting from factors associated with the abandonment of the Middle Cumberland Region (MCR) of Tennessee during the Mississippian period (ca. 1000-1500 AD). My dissertation investigates whether individuals from the Late Mississippian period had a greater risk of death than individuals from the Early Mississippian period. Adult age-at-death estimates (n=545) were calculated using Transition Analysis, a Bayesian maximum likelihood method. Gompertz and Gompertz-Makeham hazard models were utilized to reconstruct the mortality profile of the MCR as they model human adult mortality and generate robust parametric mortality profiles. Rather than recount the prevalence of …

The Evaluation And Refinement Of Nonmetric Sex And Ancestry Assessment Methods In Modern Japanese And Thai Individuals, Sean D. Tallman

Doctoral Dissertations

Effective biological profiles in forensic anthropology and bioarchaeology depend on the development, validation, and refinement of population-specific methods. However, most methods were developed in North America on individuals of African and European descent, and it is unlikely that such methods can generate accurate biological profiles for Asian individuals. Moreover, Native Americans have served as biological proxies for Asians due to their distantly shared genetic history, resulting in largely untested assumptions that Native Americans and Asians are homogenous and share nonmetric sexually dimorphic skeletal features and a unique suite of cranial traits that can be used in ancestry assessment.

The Dirt On The Collins Mounds Site, Carmelita Angeles

Graduate Theses and Dissertations

Building monumental architecture has been one method used by humans to rise above an earthbound existence. In the United States, large earthen mounds were constructed from the Archaic period to the Mississippian period. The Collins Mound Site in Arkansas was recently dated to the Late Woodland period. For this study, soil samples were extracted from the northern section of the site for description and particle-size analysis. Erosion from plowing, wind, water, and gravity is the most likely process causing a decreased mound height and increased basal diameter. Mound fill likely originated near the river for two of the mounds and …

Being With Bees: An Anthropological Study On Human-Animal Relations In Southern Beekeeping, Kori Nadine Armstrong

Master's Theses

This thesis investigates the complex and dynamic communicative relationship between beekeepers and their managed honey bee colonies, providing insight into the relationship between bees, their stewards, and the interface between nature and culture. It also helps unravel the ways in which this interspecies relationship changes a beekeepers’ perception of what it means to be human. Data collection features extensive participant observation with 21 semi-structured interviews with Southern beekeepers.

The interrelationship between communication and interaction, as well as diverse ways in which messages and cues manifest in the bee yard are explored through olfactory, optical, touch, and mechanical modalities. Variables including …

Effects Of Human Maternal Placentophagy On Postpartum Maternal Affect, Health, And Recovery, Sharon Marie Young

UNLV Theses, Dissertations, Professional Papers, and Capstones

Postpartum ingestion of the afterbirth by the mother, or maternal placentophagy, is a common behavior among eutherian mammals, including non-human primates, with humans as a rare exception. Despite the conspicuous absence of placentophagy in the cross-cultural ethnographic record, the practice appears to be gaining popularity among a small but growing number of advocates in various industrialized contexts who claim that the practice provides benefits to the postpartum mother, namely the relief and prevention of postpartum blues and depressive symptoms, improved breast milk production, and enhanced bonding with their infant. Because the placenta serves as an endocrine organ throughout pregnancy and …

Effect Of Migration, Carrying Capacity, And Fecundity On The Formation Of Clinal Patterns During Range Expansions., Neha J. Angal

Electronic Theses and Dissertations

Range expansions, empirically and in simulations, lead to clinal patterns of genetic diversity. Clines are often used as spatial markers of past migrations. This study investigated the effects of migration, growth, and carrying capacities on clinal patterns during range expansions, using forward-time simulations in Nemo. Initial results show, in the absence of prior population structure, range expansions result in a loss of diversity strongly affected by migration, growth, and carrying capacity. This loss of diversity did not persist to the final generation, corresponding to 10,000 years, indicating clinal patterns are less durable than previously assumed—challenging the utility of clinal patterns …

Associations Between Male Testosterone And Immune Function In A Pathogenically Stressed Forager-Horticultural Population, Benjamin C. Trumble, Aaron D. Blackwell, Jonathan Stieglitz, Melissa Emery Thompson, Ivan Maldonado Suarez, Hillard Kaplan, Michael Gurven

ESI Publications

Objectives—Despite well-known fitness advantages to males who produce and maintain high endogenous testosterone levels, such phenotypes may be costly if testosterone-mediated investment in reproductive effort trade-off against investment in somatic maintenance. Previous studies of androgen-mediated trade-offs in human immune function find mixed results, in part because most studies either focus on a few indicators of immunity, are confounded by phenotypic correlation, or are observational. Here the association between male endogenous testosterone and 13 circulating cytokines are examined before and after ex vivo antigen stimulation with phytohaemagglutinin (PHA) and lipopolysaccharides (LPS) in a high pathogen population of Bolivian forager-horticulturalists.

Health Costs Of Reproduction Are Minimal Despite High Fertility, Mortality And Subsistence Lifestyle, Michael Gurven, Megan Costa, Ben Trumble, Jonathan Stieglitz, Bret Beheim, Daniel Eid Rodriguez, Paul L. Hooper, Hillard Kaplan

ESI Publications

Women exhibit greater morbidity than men despite higher life expectancy. An evolutionary life history framework predicts that energy invested in reproduction trades-off against investments in maintenance and survival. Direct costs of reproduction may therefore contribute to higher morbidity, especially for women given their greater direct energetic contributions to reproduction. We explore multiple indicators of somatic condition among Tsimane forager-horticulturalist women (Total Fertility Rate = 9.1; n = 592 aged 15–44 years, n = 277 aged 45+). We test whether cumulative live births and the pace of reproduction are associated with nutritional status and immune function using longitudinal data spanning 10 …

Teaching: Natural Or Cultural?, David F. Lancy

Sociology, Social Work and Anthropology Faculty Publications

In this chapter I argue that teaching, as we now understand the term, is historically and cross-culturally very rare. It appears to be unnecessary to transmit culture or to socialize children. Children are, on the other hand, primed by evolution to be avid observers, imitators, players and helpers—roles that reveal the profoundly autonomous and self-directed nature of culture acquisition (Lancy in press a). And yet, teaching is ubiquitous throughout the modern world—at least among the middle to upper class segment of the population. This ubiquity has led numerous scholars to argue for the universality and uniqueness of teaching as a …

High Resting Metabolic Rate Among Amazonian Forager-Horticulturalists Experiencing High Pathogen Burden, Michael Gurven, Benjamin C. Trumble, Jonathan Stieglitz, Gandhi Yetish, Daniel Cummings, Aaron D. Blackwell, Bret Beheim, Hillard Kaplan, Herman Pontzer

ESI Publications

Objectives—Resting metabolic rate (RMR) reflects energetic costs of homeostasis and accounts for 60-75% of total energy expenditure (TEE). Lean mass and physical activity account for much RMR variability, but the impact of prolonged immune activation from infection on human RMR is unclear in naturalistic settings. We evaluate the effects of infection on mass-corrected RMR among Bolivian forager-horticulturalists, and assess whether RMR declines more slowly with age than in hygienic sedentary populations, as might be expected if older adults experience high pathogen burden.

Materials and Methods—RMR was measured by indirect calorimetry (Fitmate MED, Cosmed) in 1,300 adults aged 20-90 …

A History Of Violence: 3000 Years Of Interpersonal And Intergroup Conflicts From The Initial To The Early Colonial Periods In The Peruvian Central Coast. A Bioarchaeological Perspective, María Del Carmen Vega Dulanto

Electronic Thesis and Dissertation Repository

The purpose of this study is to test research questions about the development of violence on the Peruvian central coast during the pre-Hispanic and Early Colonial times. This is the first study to provide a diachronic analysis of violence on the central coast. One null hypothesis was tested and falsified: that there are no differences in the prevalence and pattern of trauma over time on the central coast of Peru. Two complementary questions were also addressed: 1) Is there a relation between sociopolitical changes, natural catastrophes, competition for resources and violence? and 2) How did violence affect specific segments of …

Population Genetic Analysis Of The Critically Endangered Black-And-White Ruffed Lemur (Varecia Variegata) In Ranomafana National Park, Madagascar, Amanda Mancini

Theses and Dissertations

This study sought to determine the efficacy of Ranomafana National Park (RNP) in preserving genetic diversity and gene flow in black-and-white ruffed lemurs (Varecia variegata). Results indicate that RNP successfully promotes gene flow between V. variegata groups, although genetic diversity at this site is low compared to other lemur taxa.

Total Energy Expenditure In Captive Sapajus Apella, Wren Edwards

Theses and Dissertations

Primates expend approximately 50% less energy (kcal/day) for their body size than other eutherians. Using the doubly labeled water method, I investigated total energy expenditure (TEE) and physical activity in Sapajus apella. S. apella TEE was similar (p=0.67) to other platyrrhines, but 54% lower than expected for body mass.

A Quantitative Genetic Analysis Of Craniofacial Variation In Baboons, Jessica Lynn Joganic

Arts & Sciences Electronic Theses and Dissertations

This dissertation is an explication of baboon craniofacial variation and its genetic basis. Intraspecific variation is the result of input from and complex interactions among genetic information, functional demands, and developmental processes. The relative effect of each of these on craniofacial variation, as well as the degree of inter-trait covariance, determines whether traits can respond to selection and what that response might look like. Using a sample of pedigreed baboons, I quantify craniofacial variation to address specific questions regarding the distribution and magnitude of phenotypic, genetic, and environmental variation patterns. In addition, I identify regions of the genome containing genetic …
