Complexities Of Companionship: Exploring The Human-Dog Relationship Through Mtdna Analysis Of Bridge River Canine Remains, Seth Warnick

Graduate Student Theses, Dissertations, & Professional Papers

Dogs (Canis lupus familiaris) hold an unquantifiable level of cultural influence and companionship across swathes of societies all over the globe. While dogs are genetically very distinct from Homo sapiens, throughout human history the two organisms have spread across the world together and have biologically gone through similar selective, social, and environmental constraints. Today the biological makeup of dog breeds is incredibly diverse, however, the archaeological record and genetic research has provided insight into the humble beginnings of a relationship between humans and dogs that has transcended the fabric of emerging civilization itself. Located on the Northwest interior plateau, Bridge …

Estimating The Sex Of A Skeleton Using Measurements Of The Femur: Assessing Accuracy Among People Of Different Ancestry And Historic Periods, Hannah Decker

Graduate Research Theses & Dissertations

Two of the most common elements used for sex estimation in humans are the pelvis and the skull, as measurements of these two regions can provide highly accurate results. However, in some forensic cases and archaeological sites, the skull and pelvis may be damaged or missing. As a result, it is important to develop methods for estimating the sex of an individual from other bones of the body. In this study, I specifically examined the femur and determined classification accuracy rates for six femoral measurements: the supero-inferior neck diameter, epicondylar breadth, vertical head diameter, transverse femoral head diameter, femoral shaft …

Morphometric Ancestral Analysis Of Infraorbital Foramen And Maxillo-Facial Landmarks Of Adult North American Skulls Using X-Ray And Computed Tomography Scans, Anna-Marie Lynn David

Graduate Student Theses, Dissertations, & Professional Papers

Skeletal remains provide a variety of information about a species population and the sub populations within that species. The infraorbital foramen has previously been used to understand dietary niches, paleoecology, the nervous system, and the effect of the nervous system on other bone functions in the facial region in humans and other mammals. In medicine, the precise location of the infraorbital foramen has been studied to aid and guide maxillo-facial procedures and surgeries. In this research project, the null hypothesis states that the placement and location of the infraorbital foramen in relation to other facial landmarks were the same between …

A Comparative Analysis Of Homicide Rates Utilizing The University Of Tennessee Forensic Data Bank, Anna F. Hampton

Graduate Student Theses, Dissertations, & Professional Papers

Homicide has piqued the interest of society through media not only in the 21^st century, but also dating back to the 1800s with crime fiction novels. Homicide holds the attention of our society with crime drama television series and has become part of American culture. With the attention that homicide receives, studies focusing on homicide are therefore important. This research utilizes the University of Tennessee Forensic Data Bank (FDB) to examine and compare homicide rates to the Global Study on Homicide conducted by the United Nation Office on Drugs and Crime (UNODC). Variables examined include sex, ancestry, cause of …

Alas, Poor Yorick: A Dna Analysis Of Ancestry Using Crania, Claire Hanson

Graduate Student Theses, Dissertations, & Professional Papers

Current methods for estimating ancestry in biological profiles provided to law enforcement and forensic collections rely heavily on the use of metric and non metric methods such as FORDISC 3.1 and “trait lists.” The reliance on these methods has led to inaccurate and ambiguous ancestry estimations, as many metric and non metric methods are subjective and cannot be statistically tested for error rates. As a result, forensic collections, such as the University of Montana Forensic Collection, could potentially house remains that have been inaccurately curated. In order to test the accuracy of curation in the UMFC, DNA samples were extracted …

The History Of Admixture In African Americans, Jessica M. Gross

Anthropology ETDs

African American admixture has been a focal topic of genetic studies since the mid-20^thcentury. Generally, these studies estimate individual- and population-level African and European ancestry proportions. Some of these studies fit unrealistic admixture models to the patterns of genetic diversity in African Americans to determine both the onset time of admixture between Africans and Europeans, and the per-generation contribution of Europeans.

This research has failed to consider the contribution of the millions of Africans who migrated, either forcibly or by choice, to North America during and after slave importation, and failed to consider how changing social dynamics have …

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.

Estimating Ancestry And Genetic Diversity In Admixed Populations., Anthony Koehl

Anthropology ETDs

Admixture is a form of gene flow that occurs when long separated populations come into contact and exchange mates. Admixture has been a primary mechanism in the formation of many modern human populations. The genetic characteristics of an admixed population are intermediate to, yet distinct from, those of its ancestors. In this dissertation, I investigate biological and statistical factors that enter into the analysis of admixed populations using genetic marker data. In chapters one and two, I use genotype data from published sources that contain 618 microsatellite loci. In chapter three, I simulate genotypes of 500 microsatellite loci. In chapter …

An Evaluation Of Metric Methods Of Race Differentiation In The Human Pelvic Girdle For The Application Of Expert Witness Testimony, Laura Natalie Yurka

Master's Theses

Research has shown that measurements from the pelvic bones and femur can be utilized for race estimation when the skull is absent or damaged. The literature reported levels up to 95% accuracy when utilizing discriminant function analysis to simultaneously classify race and sex. This research examined the previously reported methods of race estimation within the evidence standards for forensic science as well as current statistical standards. New metric measurements from the pelvis and femur were also proposed and tested to assess their utility as race indicators. Finally, this research addressed concerns that skeletal collections like the Robert J. Terry Skeletal …

Postcranial Osteometric Assessment Of Korean Ancestry, Elizabeth Carol Okrutny

Electronic Theses and Dissertations

The determination of ancestry is an important part of an individual's identification when creating a biological profile. This thesis scrutinizes postcranial variation using over 65 osteometric sorting measurements in an attempt to identify those measurements that display the most significant differences among Koreans, Africans, and Europeans. Data was collected from four American skeletal collections and one South Korean skeletal collection for a total sample population of 306 individuals: 24 of Korean ancestry, 66 of African ancestry, and 216 of European ancestry. In an effort to minimize the number of measurements needed for ancestral assessment, stepwise discriminant analysis was performed for …

Determining Sex And Ancestry Of The Hyoid From The Robert J. Terry Anatomical Collection, Sarah Kindschuh

Electronic Theses and Dissertations

One of the basic goals of the physical anthropologist is to create a biological profile, consisting of sex, ancestry, age, and stature, from the skeletal material that they are presented with. This thesis seeks to explore size and shape differences related to sex and ancestry from the hyoid bones of the Robert J. Terry Anatomical Collection in order to gauge its usefulness in the process of developing a biological profile. A series of measurements were taken from 398 hyoids and analysis was conducted using a number of statistical methods. Independent samples t-tests were used to examine size differences between sexes …
