Anthropometric Measures Of Hadza Forager Children And Juveniles: Implications For Anthropology And Human Biology, Elle Ford, Alyssa N. Crittenden

McNair Poster Presentations

Understanding growth trajectories during child development is important for the fields of human biology, public health, medicine, and evolutionary medicine. To date, the majority of current references for childhood development and health are primarily derived from the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). To ensure a child is developing properly, is equipped with proper nutrition, and will sustain a healthy life through adolescence and adulthood, these measurements and standards are necessary. The current study aims to test whether or not these standards are applicable in non-industrial small-scale societies where differences from western populations …

A Natural History Of The Drag Queen Phenomenon, Michael Moncrieff, Pierre Lienard

Anthropology Faculty Research

The drag queen cultural phenomenon has been described at length. However, the depiction of outlandish and hyperbolic womanhood and taunting and formidable behavior at the core of drag queens' public persona has still to be fully accounted for. We argue that these aspects of the drag queen's public appearance could best be understood in a signaling framework. Publicly donning extravagant woman's costumes attracts harassment and brings financial, mating, and opportunity costs, generating the conditions for the transmission of honest signals. By successfully withstanding those odds, drag queen impersonators signal strategic qualities to members of the gay community. Data collected among …

Do Step- And Biological Grandparents Show Differences In Investment And Emotional Closeness With Their Grandchildren?, Peter B. Gray, Elizabeth Brogdon

Anthropology Faculty Research

Human children are raised by a variety of caregivers including grandparents. A few studies have assessed potential differences in direct caregiving, financial expenditures, and emotional closeness between biological and step-grandparents. Drawing upon kin selection theory, we hypothesized that step-grandparents would provide less care and be less emotionally close to grandchildren than would biological grandparents. A sample of 341 heterosexual U.S. adults 25-35 years of age in a long-term partnership and with a biological child 5 years of age or younger were recruited via Amazon Mechanical Turk. Subjects provided sociodemographic information and answered questions about the dynamics between their own parent/stepparent …

Polyandry Around The World, Laura A. Benedict

Calvert Undergraduate Research Awards

Polyandry is the umbrella term for one woman maintaining sexual access to more than one man. This work is a comparison of forty-three societies as examples of the six types of polyandry practiced around the world. In some types, the sexual acts are part of a marriage contract involving three or more people. In some types, the marriage involves only two people, but the sexual access of the wife extends beyond the marriage. In one type, the extra-marital sexual activity is expected, and not entirely voluntary by all parties. This survey is the first to describe all six types with …

Examining Style In Virgin Branch Corrugated Ceramics, Shannon Horton, Karen Harry

Anthropology Faculty Research

In this article, we examine variation in the corrugation styles of ceramics from the Virgin Branch Puebloan culture. These ceramics were recovered from two regions: the Moapa Valley of southern Nevada and the Mt. Dellenbaugh area of northwestern Arizona. Three wares—Shivwits, Moapa, and Tusayan—are examined, each of which was produced in different locations. Similarities and differences in corrugation styles between these wares are used to investigate ceramic learning frameworks and the nature of the pottery production and distribution system.

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: …

Food Processing And Cooking Technology Of The Mimbres Mogollon (Early Pithouse Period Through The Mimbres Classic A.D. 200-1130), Ashley Morgan Lauzon

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examines food processing and cooking technology of the Mimbres Mogollon culture from A.D. 200-1130. Food processing and cooking technology includes any tool (chipped stone, ground stone, ceramics, basketry/perishables, etc.) or feature (fire-features, etc.) used to prepare, process, and cook food. Data on this technology as a whole is lacking in the region. The goal of this research is to document and explore the changes and developments in food-related technology over time and to investigate possible factors that influenced its development.

To document this technology over the course of approximately 1000 years, four case study sites were used: The …

Fecal Metabolome Of The Hadza Hunter-Gatherers: A Host-Microbiome Integrative View, S. Turroni, J Fiori, S Rampelli, S. L. Schnorr, C. Consolandi, M. Barone, E. Biagi, F. Fanelli, M. Mezzullo, Alyssa Crittenden, A. G. Henry, P. Brigidi, M. Candela

Anthropology Faculty Research

The recent characterization of the gut microbiome of traditional rural and foraging societies allowed us to appreciate the essential co-adaptive role of the microbiome in complementing our physiology, opening up significant questions on how the microbiota changes that have occurred in industrialized urban populations may have altered the microbiota-host co-metabolic network, contributing to the growing list of Western diseases. Here, we applied a targeted metabolomics approach to profile the fecal metabolome of the Hadza of Tanzania, one of the world's few remaining foraging populations, and compared them to the profiles of urban living Italians, as representative of people in the …

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 …

The Proof Is In The Pots: Residue Analysis Of Virgin Branch Puebloan Ceramics, Brenna Lynn Wilkerson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study focuses on better understanding diet and subsistence strategies among Virgin Branch Puebloan groups living in the Moapa Valley in southern Nevada and on the Shivwits Plateau in northwestern Arizona. Gas chromatography-mass spectrometry (GC-MS) was used to identify absorbed food residues in three types of Virgin Branch Puebloan ceramics (Moapa Gray Ware, Shivwits Ware, and Tusayan Virgin Series). The data produced by the residue analysis were used to compare patterns of subsistence between Virgin Branch Puebloan sites in the lowlands along the Muddy River and at upland sites on the Shivwits Plateau as these two areas have different environments …

Footprints Reveal Direct Evidence Of Group Behavior And Locomotion In Homo Erectus, K. G. Hatala, N T. Roach, K R. Ostrofsky, R. E. Wunderlich, H. L. Dingwall, Brian Villmoare, D. J. Green, J. W.K. Harris, D. R. Braun, B. G. Richmond

Bipedalism is a defining feature of the human lineage. Despite evidence that walking on two feet dates back 6-7 Ma, reconstructing hominin gait evolution is complicated by a sparse fossil record and challenges in inferring biomechanical patterns from isolated and fragmentary bones. Similarly, patterns of social behavior that distinguish modern humans from other living primates likely played significant roles in our evolution, but it is exceedingly difficult to understand the social behaviors of fossil hominins directly from fossil data. Footprints preserve direct records of gait biomechanics and behavior but they have been rare in the early human fossil record. Here …

Enterocyte-Associated Microbiome Of The Hadza Hunter-Gatherers, S. Turroni, S Rampelli, M Centanni, S. L. Schnorr, C. Consolandi, M. Severgnini, C. Peano, M. Soverini, M. Falconi, Alyssa Crittenden, A. G. Henry, P. Brigidi, M. Candela

Anthropology Faculty Research

By means of a recently developed non-invasive ex vivo minimal model based on the interaction of the human enterocyte-like HT29 cell line and fecal slurries, we explored the enterocyte-associated microbiome of 21 Hadza hunter-gatherers and nine urban living Italians. Though reductionist, this model allows inferring the microbiota structural and functional arrangement as it interacts with enterocytes. Microbial suspensions obtained from Hadza or Italian stools were first evaluated for structural integrity by high resolution-scanning electron microscopy and co-incubated with HT29 cell monolayers. The enterocyte adherent microbiota fraction was then characterized by 16S rRNA gene sequencing and predictive functional profiling using PICRUSt. …

Reconstructing hominin paleoecology is critical for understanding our ancestorsâ € diets, social organizations and interactions with other animals. Most paleoecological models lack fine-scale resolution due to fossil hominin scarcity and the time-Averaged accumulation of faunal assemblages. Here we present data from 481 fossil tracks from northwestern Kenya, including 97 hominin footprints attributed to Homo erectus. These tracks are found in multiple sedimentary layers spanning approximately 20 thousand years. Taphonomic experiments show that each of these trackways represents minutes to no more than a few days in the lives of the individuals moving across these paleolandscapes. The geology and associated vertebrate …

Commingled Tombs And Arcgis: Analyzing The Mortuary Context And Taphonomy At Bronze Age Tell Abraq, Maryann Calleja

UNLV Theses, Dissertations, Professional Papers, and Capstones

The use of global positioning systems (GPS) and mapping software are commonplace in today’s archaeology. Artifacts and human remains can be plotted on maps and digitized immediately on sites allowing for instant analysis. Yet, the use of GPS in some locations may not be feasible due to natural or human-made terrain features such as canopy cover, densely built urban environments, caves, or other environments where satellite access may be limited. Additionally, prior to the widespread use of GPS, field archaeologists had to rely solely upon systematic, detailed notes and sketches. Such was the case at the Bronze Age tomb at …

Small-Scale Societies Exhibit Fundamental Variation In The Role Of Intentions In Moral Judgment, H. C. Barrett, A Bolyanatz, Alyssa Crittenden, D. M.T. Fessler, S. Fitzpatrick, M. Gurven, J. Henrich, M. Kanovsky, G. Kushnick, A. Pisor, B. A. Scelza, S. Stich, C. Von Rueden, W. Zhao, S. Laurence

Anthropology Faculty Research

Intent and mitigating circumstances play a central role in moral and legal assessments in large-scale industrialized societies. Although these features of moral assessment are widely assumed to be universal, to date, they have only been studied in a narrow range of societies. We show that there is substantial cross-cultural variation among eight traditional small-scale societies (ranging from hunter-gatherer to pastoralist to horticulturalist) and two Western societies (one urban, one rural) in the extent to which intent and mitigating circumstances influence moral judgments. Although participants in all societies took such factors into account to some degree, they did so to very …

The Teshik-Tash Child: Evolutionary Montage During The Middle Paleolithic, Nirosh Moodley, Alesha Pettit

AANAPISI Poster Presentations

Discovered in 1938 in the Bajsun district of southern Uzbekistan, Teshik-Tash 1 represents a juvenile male hominin, aged between nine and eleven years old. He was classified as Homo neanderthalensis. Two pertinent characteristics of the find’s in situ context provided the backdrop for this classification. Firstly, the Teshik-Tash child was buried with associated grave goods surrounded by a Middle Paleolithic assemblage which has been described as “Mousterian-like” (Glantz et al, 2009: 45). Secondly, the very location of this find was the furthest eastern extent of hominin discoveries outside of the Levant. Recent research, however, challenges this boundary by questioning …

The Painted Motifs Of Cypriot Ceramic Art: A Study Of Iconography & Identity, Paige Bockman

UNLV Theses, Dissertations, Professional Papers, and Capstones

The aim of this master’s thesis is to explore the iconography of Chalcolithic (c. 3900-2300 cal. BC) Cyprus using ceramic motifs and identify their potential use in revealing differences between the cultural identity present at archaeological sites, as well as the possible causes of such variation. By exploring the existence and origins of subtle differences between the iconographic repertoires of related sites, the study seeks a better understanding of the movement of both ideas and symbols, and how the meaning of symbols developed within the context of a site.

Currently, Cypriot Chalcolithic sites are believed to be largely homogeneous in …

The Influence Of Iron On Arctic Thule Migration Patterns, Alina T. Aquino

UNLV Theses, Dissertations, Professional Papers, and Capstones

Arctic scholars have yet to fully understand the reasons behind the migration of Thule culture from the western to the eastern Arctic. This rapid movement across such a vast area into environmentally diverse regions marks a critical period of cultural change that is usually summarized by two theoretical positions. Ecological theories postulated environmental changes placed selective pressures on traditional food sources that required Thule hunters to follow migrating prey. Theories that focused on material acquisition alternately proposed the Thule followed the trail of meteoric iron eastward into northwestern Greenland.

This research sought to examine the eastward Thule migration from another …

Picrolite And The Cypriot Neolithic: An Experimental Study, Forrest Dayton Jarvi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Picrolite, a fibrous green stone originating in the Troodos mountains on the island of Cyprus, appears in the archaeological record almost from the very earliest sites on the island. Thus far, few publications have addressed the material from anything but a descriptive perspective. Research at the Aceramic Neolithic site of Kritou Marottou Ais Giorkis has uncovered a wide variety of picrolite artifacts since excavations began in 1997. Preliminary experimental studies have begun to explore the ease of both obtaining and manipulating the material using only local materials and unassisted manpower. This thesis presents a three-part investigation into the place of …

Effects Of Human Maternal Placentophagy On Maternal Postpartum Iron-Status, Laura Kathleen Gryder

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recently, human maternal placenta ingestion, known as placentophagy, has emerged as a rare but growing practice among postpartum mothers in industrialized societies, and is currently found in both home birth and hospital birth settings. The practice is purported to result in certain health benefits for postpartum mothers, some of which could be related to the iron content in full-term placenta (e.g., increased energy and an improved and more rapid postpartum recovery, among others). The aim of this research project was to investigate the effect of encapsulated placentophagy on maternal postpartum iron status via a randomized, double-blind, placebo-controlled pilot study (n=28). …

An Investigation Into Human To Dog Attachment Systems And Their Influence On The Degree Of Aversion Used In Training, Shelly Volsche

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of my Master’s Thesis research is to determine if and what type of relationship exists between owner-to-dog attachment levels and the degree of aversion used in dog training. I also sought to determine if owner characteristics such as parental status, income, gender, and the like influenced the degree of aversion used. My primary hypothesis is that a negative correlation exists between attachment to one’s dog and aversion used in training. That is, as attachment scores increase, aversion scores decrease. In addition to testing this hypothesis, I collected data to determine if there are correlations between the following: gender …

Food Sharing Among Hadza Hunter-Gatherer Children, Alyssa N. Crittenden, David A. Zes

Anthropology Faculty Research

Human prosociality is one of the defining characteristics of our species, yet the ontogeny of altruistic behavior remains poorly understood. The evolution of widespread food sharing in humans helped shape cooperation, family formation, life history, language, and the development of economies of scale. While the behavioral and ecological correlates of food sharing among adults are widely studied, very little is known about food sharing among children. Here, in the first study to analyze the food sharing patterns of hunter-gatherer children, we show that while sharing may be biased towards kin, reciprocity characterizes the majority of all sharing dyads, both related …

Metagenome Sequencing Of The Hadza Hunter-Gatherer Gut Microbiota, Simone Rampelli, Stephanie L. Schnorr, Clarissa Consolandi, Silvia Turroni, Marco Severgnini, Clelia Peano, Patrizia Brigidi, Alyssa N. Crittenden, Amanda G. Henry, Marco Candela

Anthropology Faculty Research

Through human microbiome sequencing, we can better understand how host evolutionary and ontogenetic history is reflected in the microbial function. However, there has been no information on the gut metagenome configuration in hunter-gatherer populations, posing a gap in our knowledge of gut microbiota (GM)-host mutualism arising from a lifestyle that describes over 90% of human evolutionary history. Here, we present the first metagenomic analysis of GM from Hadza hunter-gatherers of Tanzania, showing a unique enrichment in metabolic pathways that aligns with the dietary and environmental factors characteristic of their foraging lifestyle. We found that the Hadza GM is adapted for …

Chipped Stone Analysis Of The Yamashita Sites In Moapa Valley, Nevada: A Technological Organization Approach, Tatianna Menocal

UNLV Theses, Dissertations, Professional Papers, and Capstones

Archaeological research on the lowland branch of the Virgin Branch Puebloan (VBP) has been conducted steadily throughout the 20th century. Much of this research occurred in the early half of the century with initial research conducted by Mark R. Harrington and later archaeology designed as salvage work due to public works projects, including the construction of Hoover Dam and the development of Lake Mead (Ahlstrom and Roberts 2012). The initial archaeology in the area was focused on classifying and characterizing the Puebloan occupation in the region, as the discovery of habitation sites in the area represented the farthest western extension …

Bodies In Motion: A Bioarchaeological Analysis Of Migration And Identity In Bronze Age Cyprus, Anna Jean Osterholtz

UNLV Theses, Dissertations, Professional Papers, and Capstones

The analysis of human remains from the Bronze Age on Cyprus offers insights into underlying issues of social change and identity formation. Data collected from human remains from six sites throughout the southern half of Cyprus dating to the PreBA through the ProBA (2400--1100 BC) provide insight into social cohesion and group identity during this time of constant social change. Human remains were used to provide demographic data (such as number of individuals interred together, age at death and sex), health profiles (such as incidence of childhood stress, pathologies, and trauma), and robusiticty. Specifically, these data were gathered to provide …

Watercraft, People, And Animals: Setting The Stage For The Neolithic Colonization Of The Mediterranean Islands Of Cyprus And Crete, Katelyn Dibenedetto

UNLV Theses, Dissertations, Professional Papers, and Capstones

One of the most significant developments in human history was the “Neolithic Revolution,” which first began around 11,000 years ago in mainland Southwest Asia. It resulted in not only the economic reorientation from hunting and foraging to herding and farming based on domesticate resources, but also significant changes in human technology, demography, society, political organization, ideology and human relationships to the environment. In order to understand this momentous process, however, it is important to understand the events that set it in motion. This is particularly the case when dealing with oceanic Mediterranean islands, specifically Cyprus and Crete, where there is …

The Bioarchaeology Of Social Order: Cooperation And Conflict Among The Mimbres (Ad 550-1300), Kathryn Mary Baustian

UNLV Theses, Dissertations, Professional Papers, and Capstones

Interpersonal conflict, social control, and culturally sanctioned violence are all potential modes of effecting change amongst most human groups. This research investigates the complex relationship between interpersonal violence, human skeletal biology, and social identity among prehistoric agricultural communities in the American Southwest. Using bioarchaeology as a research framework, the data presented in this study reveal patterns that can be used to better understand how violence is utilized or avoided in any time period. Bioarchaeology is well suited to investigate violence because it integrates the most direct evidence of conflict (traumatic skeletal injury) with detailed archaeological reconstructions of past human experiences. …

Sexuality Among Fathers Of Newborns In Jamaica, Peter B. Gray, Jody-Ann Reece, Charlene Coore-Desai, Twana Dinnall-Johnson, Sydonnie Pellington, Maureen Samms-Vaughan

Anthropology Faculty Research

Background While a growing body of research has addressed pregnancy and postpartum impacts on female sexuality, relatively little work has been focused upon men. A few studies suggest that a fraction of men report decreases in libido during a partner’s pregnancy and/or postpartum, with alterations in men’s sexual behavior also commonly aligning with those of a partner. Here, we investigate sexuality among fathers of newborn children in Jamaica. In Jamaica, as elsewhere in the Caribbean, relationship dynamics can be fluid, contributing to variable paternal roles and care, as well as a high fraction of children born into visiting relationships in …
