The Role Of Forensic Anthropological Techniques In Identifying America's War Dead From Past Conflicts, William Belcher, Calvin Y. Shiroma, Lesley A. Chesson, Gregory E. Berg, Miranda Jans

Anthropology Faculty Publications

The Scientific Analysis Directorate of the U.S. Department of Defense's (DoD) Defense POW/MIA Accounting Agency (DPAA) is a unique entity within the U.S. Government. This agency currently houses the world's largest, accredited skeletal identification laboratory in the world, in terms of the size of the scientific staff, global mission, and number of annual identifications. Traditional forensic anthropology is used for the formation of a biological profile (biological sex, stature, population affinity/ancestry, and age) as well as trauma and pathologies that may be compared with historical records and personnel files. Since World War II, various scientists associated with DoD have conducted …

African Land Mammal Ages, John Van Couvering, Eric Delson

Publications and Research

We define 17 African land mammal ages, or AFLMAs, covering the Cenozoic record of the Afro-arabian continent, the planet’s second largest land mass. While fossiliferous deposits are absent on the eroded plateau of the continent’s interior, almost 800 fossil genera from over 350 locations have now been identified in coastal deposits, karst caves, and in the Neogene rift valleys. Given a well-developed geochronologic framework, together with continuing revision to the fossil record—both stimulated by the story of human evolution in Africa—and also to compensate for the variation in fossil ecosystems across such great distances, the AFLMAs are biochronological units defined …

Grandmotherhood In Ukraine: Behavioral Variation And Evolutionary Implications, Sofiya Shreyer

Masters Theses

Grandmothers are known to increase the health and well-being of their grandchildren in many different populations. However, grandmothers may vary in their contributions based on their relatedness to their grandchildren. In some populations, maternal grandmothers decrease the risk of mortality and increase the health of their grandchildren more than paternal grandmothers. Grandmaternal influence also sometimes varies based on the gender of the grandchild. The behavioral mechanisms of grandmaternal investment are not well understood and have not been explored in the heavily intergenerational context of Eastern Europe. This study examines the behavioral variation of sixty-two Ukrainian grandmothers through interviews and a …

Nutrition At Tipu: A Comparative Analysis Of Juvenile Health In Maya Populations, Sydnie A. Bianchi

Master's Theses

The site of Tipu in west central Belize provided a foothold for Spanish missionaries in the 17^th century. The effects of contact on adults among the 550 burials recovered in the cemetery there have been well studied, but the children have received less attention. Therefore, this study examined juvenile health through four markers: Linear Enamel Hypoplasia (LEH), a non-specific marker of health disruptions; Porotic Hyperostosis (PH), an indicator of anemia; and Periostitis, an indicator of infection. Some 131 individuals were evaluated using criteria developed by Steckel, Sciulli, and Rose (2002). The results were compared to Late Classic Copán (Storey, …

Social Processes Through The Lens Of Network Science In Spider Monkeys, Emily R. Boeving

FIU Electronic Theses and Dissertations

This dissertation presents a series of empirical studies which aim to deepen and broaden what is known about social processes in spider monkeys. In recent decades, the burgeoning field of network science has brought a new perspective to many disciplines. Although network science has emerged in multiple content areas (e.g., neuroscience, economics), the application and utility of social network analysis to quantify social processes has seen great advances. Sociality and component processes have been described as mystifying and left many perplexed at the basic question, “What is social?” There is no easy answer to this question but one issue is …

Do Actions Speak Louder Than Words? Communicative Frequencies And Multimodality In Ring-Tailed Lemurs (Lemur Catta), Hilary Hager

Electronic Thesis and Dissertation Repository

The study of multimodal communication in primatology has increased only recently. At present, there are no on-going investigations of multimodal communication in ring-tailed lemurs (Lemur catta), despite the body of research on this species. I investigated how different modes of L. catta inter-individual multimodal communication are socially coordinated and integrated by examining frequencies of occurrence within four potential biological and social factors: age, troop affiliation, sex, and dominance rank. Research was conducted over four months at the Duke Lemur Center, Durham, NC, on 14 individuals from three separate troops of captive, free-ranging L. catta. Results demonstrate communicative …

Dietary Development And Nutritional Ontogeny In Gorilla Beringei : A Multi-Layered, -Omics Approach, Emma C. Cancelliere

Dissertations, Theses, and Capstone Projects

In species who consume folivorous diets, immature individuals must contend with the challenges of extracting nutrients from fibrous foods before dietary adaptations and strategies are fully developed. Additionally, immatures have distinct nutritional needs to support their stage-specific metabolic and biophysiological requirements. To meet these stage-specific needs, while constrained by underdeveloped feeding strategies and digestive capacities, immatures may adopt distinct diets better suited to their specific developmental context. However, where dietary modification is constrained by low dietary diversity or landscape homogeneity, it is unclear how immature individuals compensate through alternative strategies. In turn, little is known about the nutritional and life …

Relationship Of Posterior Intracranial Venous Structures In Homo Sapiens And Handedness, Brianne Finley

Theses and Dissertations

The transverse sinus spans the endocranial surface of the occipital bone and ultimately transmits deoxygenated blood to the sigmoid sinus and jugular vein en route to the heart. This paired sinus tends to be more defined on either the left or right side in human crania. Left and right dominance, or the use of one side of the body more than the other, leaves traces on the human skeleton. Methods to determine handedness upon examination of various elements of the human skeleton mostly focus on the use of the extremities, while little research exists examining the skull for evidence of …

Archaeology Or Crime Scene? Teeth Micro And Macro Structure Analysis As Dating Variable, Jessica A. Vincenty

Student Theses

Simple methods to aid in the determination of forensic or archaeologic relevancy of skeletonized remains have been researched since the 1950s. With advances in microscopic imaging techniques and machine learning computer data analysis methods the relevancy of decontextualized, comingled remains has room for improvement. This thesis is a study done to pioneer a new approach to analyzing dental skeletal remains to determine forensic relevancy.

Archaeological dental samples collected from the ancient city of Ur in modern day southern Iraq in addition to modern dental extractions were processed for scanning electron microscopy imaging. Archaeological and modern samples displayed different surface and …

Market Integration And Soil-Transmitted Helminth Infection Among The Shuar Of Amazonian Ecuador, Theresa E. Gildner, Tara J. Cepon-Robins, Melissa A. Liebert, Samuel S. Urlacher, Joshua M. Schrock, Christopher J. Harrington, Felicia C. Madimenos, J. Josh Snodgrass, Lawrence S. Sugiyama

Publications and Research

Background

Soil-transmitted helminth (STH) infections have many negative health outcomes (e.g., diarrhea, nutritional deficiencies) that can also exacerbate poverty. These infections are generally highest among low-income populations, many of which are also undergoing market integration (MI; increased participation in a market-based economy). Yet the direct impact of MI-related social and environmental changes on STH infection patterns is poorly understood, making it unclear which lifestyle factors should be targeted to better control disease spread. This cross-sectional study examines if household infrastructure associated with greater MI is associated with lower STH burdens among Indigenous Ecuadorian Shuar.

Birth Control Behind Bars: An Anthropological Perspective On The Care Of Captive Bonobos, Tylyn A. Recore-Dagsaan

PANDION: The Osprey Journal of Research and Ideas

Bonobos are one of our closest living primate relatives. They are primarily known for their unique social structure and sexual behavior. In their native setting, the Democratic Republic of the Congo, bonobos are often seen engaging in sexual behaviors not only for reproduction, but for social reasons too. Unfortunately, research in the wild is difficult because of political unrest and rapidly declining population numbers. Since bonobos are endangered, it is crucial that we maintain and properly care for a captive population to ensure the survival of the species. A captive setting provides a safe, controlled environment for researchers to observe …

Epigenetics A Decolonizing Science, Wade Paul

Electronic Thesis and Dissertation Repository

Epigenetics is the study of gene expression that does not entail alterations to the actual DNA. Decolonization is a theoretical and political movement that seeks to deconstruct colonial institutions and ideologies and reconstruct new and balanced approaches that accept and respect Indigenous worldviews. This project studies the decolonizing potential of epigenetics. Using genealogy as the method, the study establishes a long history of reductionist and deterministic thought that shaped the study of genetic science. Particular instances like thrift gene theory are explored to highlight how genetic explanations have been detrimental to the health and wellbeing of Indigenous people and illustrate …

Reconsidering The Obstetrical Dilemma: Correlations Between Head And Pelvic Size, Kelsey Catrice Fox

LSU Master's Theses

The Obstetrical Dilemma (OD) theory has become canon in biological anthropology. The OD posits that i] dystocia results from bipedal mothers and encephalized infants, ii] contrasting selection for bipedality and obstetrics hinders locomotive efficiency, and iii] the contradicting requirement of the fetus being small enough to pass through the birth canal yet being cognitively advanced enough to cling to its mother after birth. Females, theoretically, exhibit deficient gait efficiency for the sake of successful childbirth. An obstetric advantage theory has been posited where taller individuals with a larger head size have larger pelves. If the distance between the acetabulae increases …

Climbing Performance And Ecology In Humans, Chimpanzees, And Gorillas, Elaine E. Kozma

Dissertations, Theses, and Capstone Projects

This dissertation aims to establish the effects of limb proportions and body size on the climbing performance of humans, chimpanzees, and gorillas by assessing three aspects of climbing performance: 1) energetic cost, 2) fatigue, and 3) canopy access. Whether hominins were arboreal, and to what extent, is a matter of hot debate. Specifically, the relative prominence of vertical climbing in the locomotor repertoires of various hominin taxa remains a contested issue. Over the course of human evolution, both the body size and relative hindlimb length of hominins has increased. These traits are often linked to bipedality. Long forelimbs, in contrast, …

Bones, Burials, And The Riddle Of Truth: Reconstructing The Past Through What Has Been Left Behind, Jelena M. Begonja

Dissertations, Theses, and Capstone Projects

Mortuary archaeology is known to be the study of human remains and burials. The primary focus of this work has been to study all of the elements associated in burials to learn more about the burial practices and rituals in a group’s culture, however, there is much more potential in studying burial sites than just learning about a group’s burial rituals and practices. This thesis will demonstrate that it is indeed possible to make different inferences about the rest of people’s daily lives, and the truth, based from materials found in studying burials alone. For some groups without much existing …

Ecologically Driven Changes In Subsistence Strategies: An Examination Of Bone Cross-Sectional Geometrical Properties In Hunter-Gatherers From Australia And Early Agriculturists From Belize, Ethan C. Hill

Anthropology ETDs

The primary purpose of this dissertation was to examine how changes to ecological context can urge subsistence level populations to adopt new subsistence strategies. This was accomplished by using metrics of bone strength to infer temporal behavior change in Holocene (10,000 BP – present) skeletal samples from southern Australia and southern Belize. The first paper, An Examination of the Cross-sectional Geometrical Properties of the Long Bone Diaphyses of Holocene Foragers from Roonka, South Australia, was written in collaboration with Osbjorn Pearson, Arthur Durband, Keryn Walshe, Kristian Carlson, and Frederick Grine. We compared long bone data for 69 individuals at Roonka …

An Assessment Of The Use Of Photogrammetry In Cranial Metric And Non-Metric Studies, Amy Hair

Master's Theses

Methods in biological anthropology have made tremendous leaps in recent years and with the increasing rise in technology there is no reason to suspect that this trend will be decreasing. Particularly methods in 3D digitization have not only increased but have also become more accessible in bioarchaeology. One method, photogrammetry, offers bioarcheologists a unique opportunity to easily collect and process cranial metric and non-metric data that can be used to quantify biological relatedness. While these advances are expected to continue, it is ignorant to assume that they represent a fail proof solution. A critical examination is necessary to quantify the …

Analysis Of The Evolution Of The Hominin Jaw & Dentition, Matthew Koelbel

Undergraduate Theses and Capstone Projects

The food an organism consumes impacts the evolution of its dentition and facial morphology. As the teeth of early hominins are often some of the only parts of the skeleton to be fossilized, their morphological changes throughout time are better documented and understood than many other body parts. A literature review of articles focusing on the evolution of the dentition and mandibular morphology of members of the tribe Homininae was conducted. We deduced the ways in which tool use and cooking directly affected the teeth of hominins from the late Pleistocene to Pliocene from this information. The tangible ways that …

In Vitro Immune Activation By Treponema Pallidum And The Effect On Osteoclastogenesis: First Experimental Step Towards An Integration Between Osteoimmunology And Paleopathology., Emily Ann Rich

College of Arts & Sciences Senior Honors Theses

The presence of pathogens in the human body influences the expression of pro-inflammatory cytokines by activated immune cells. These cytokines, and other factors, regulate osteoclastogenesis and osteoclast activity. Through experimental osteoimmunology, interactions between the inflammatory response and bone cell physiology may provide insight into how immune processes can be translated into the lesions or abnormalities observed in the osteological record. In this research, our objective was to determine if the cytokines produced by activated immune cells increase osteoclastogenesis and osteoclast activity. To evaluate this hypothesis, we used two main protocols, one for immune activation and one for osteoclastogenesis, that utilized …

Plant Processing Experiments And Use-Wear Analysis Of Tabon Cave Artefacts Question The Intentional Character Of Denticulated Stone Tools In Prehistoric Southeast Asia, Alfred Pawlik, Hermine Xhauflaira, Sheldon Jago-On, Timothy Vitalese, John Rey Callado, Danilo Tandang, Trishia Palconit, Dante Manipon, Claire Gaillard, Angeliki Theodoropoulou, Nicole Revel, Hubert Forestier

Sociology & Anthropology Department Faculty Publications

The presence of notches on European Palaeolithic flaked stone tools termed ‘denticulates’ has been variously ascribed to cultural, functional and taphonomic factors. In Southeast Asia prehistoric stone tool assemblages are dominated by unretouched flakes, so the rare retouched lithics, including denticulates, can be considered unique testimonies of the intention of the tool makers to control the shape and properties of tool edges. Here we report the results of plant processing experiments with modern unretouched flakes made of red jasper. Splitting plants with the help of a specific hand and arm movement (“twist-of-the-wrist”) resulted in a series of use-wear traces that …
