Cognitive Performance Across The Life Course Of Bolivian Forager-Farmers With Limited Schooling, Michael Gurven, Eric Fuerstenberg, Benjamin C. Trumble, Jonathan Stieglitz, Bret Beheim, Helen Davis, Hillard Kaplan

ESI Publications

Cognitive performance is characterized by at least two distinct life course trajectories. Many cognitive abilities (e.g. “effortful processing” abilities including fluid reasoning, and processing speed) improve throughout early adolescence and start declining in early adulthood, while other abilities (e.g. “crystallized” abilities like vocabulary breadth) improve throughout adult life, remaining robust even at late ages. Although schooling may impact performance and cognitive “reserve”, it has been argued that these age patterns of cognitive performance are human universals. Here we examine age patterns of cognitive performance among Tsimane forager-horticulturalists of Bolivia, and test whether schooling is related to differences in cognitive performance …

A Comprehensive Case Report Of The University Of Montana Case 37, Cody M. Lawson

Graduate Student Theses, Dissertations, & Professional Papers

In this professional paper I examine the human skeletal remains of one individual. The remains were analyzed to gain insight into the age, sex, ancestry, stature, weight, pathology, and trauma of the individual. Forensic anthropological methods were applied to UMFC 37. The remains of UMFC 37 represent a male, between the age of 40 and 60. He is likely a Caucasian. UMFC 37 is between 5 feet 6 inches and 5 feet 10 inches tall and weighs between 148 and 167 pounds.

Fertility And Reproduction's Niche: Human Sexual Diversity, Samuel W. Austin

Graduate Student Theses, Dissertations, & Professional Papers

Abstract: Biologically exploring the origins and forms of human sexuality is of paramount importance. Scientific research has indicated that homosexuality was linked to reproduction, fertility, and adaptive child caring strategies, traits that seem to display cross-cultural similarities. This suggests that sexual diversity may be one of human’s earliest adaptations. While most of the previous research has been on individuals of European descent, little research on Native American populations has been completed to test whether these patterns continue in their population.

The research presented here tests the Sexually Antagonistic Hypothesis for Male Homosexuality, Fraternal Birth Order Effect, and childhood atypical gender …

Juvenile Remains: Predicting Body Mass And Stature In Modern American Populations, Erin F E Pinkston

Cal Poly Humboldt theses and projects

There are increasing numbers of unidentified persons in the U.S. and abroad. To generate positive identifications, forensic anthropologists and others working in the medicolegal field employ a variety of methods to produce biological profiles to match to case files and missing persons databases. Body mass, and stature are two important components of a biological profile, and both can be estimated using regression formulae derived from skeletal metrics. In cases of unidentified juvenile remains, these are particularly important metrics, as it is difficult or impossible to determine sex in prepubescent remains, and the quality of ancestry estimation is currently under debate …

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 …

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 …

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 …

Sexual Determination From Frontal Sinus Analysis In A Subadult Population Using Archival Radiographic Records, Erica Crosta

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: …

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 …

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 …

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. …

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 …

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 …
