The discovery of 5,500 Homo heidelbergensis fossil specimens at the Sima de los Huesos archaeological site in Spain has opened up the opportunity for research to be conducted on the vocal capabilities of this species. Previous research has revealed that the range of vowel sounds an individual can produce, known as the vowel space, is directly affected by the dimensions of the vocal tract. The vowel spaces of two hominins, Homo sapiens and Homo neanderthalensis, have been reconstructed through...
Show moreThe discovery of 5,500 Homo heidelbergensis fossil specimens at the Sima de los Huesos archaeological site in Spain has opened up the opportunity for research to be conducted on the vocal capabilities of this species. Previous research has revealed that the range of vowel sounds an individual can produce, known as the vowel space, is directly affected by the dimensions of the vocal tract. The vowel spaces of two hominins, Homo sapiens and Homo neanderthalensis, have been reconstructed through previous research. However, the vowel space of Homo heidelbergensis has not yet been reconstructed. In this research, I aim to explore how the dimensions of the Homo heidelbergensis vocal tract affect the vowel space of that species. This was pursued by measuring the craniospinal dimensions of five Homo heidelbergensis specimens through three dimensional imaging software. When measurements were unattainable due to limitations in the fossil record, regression equations were used to predict missing measurements. By doing so, the vowel space of this species was reconstructed, and crucial information into the vocal capabilities of this close human ancestor was revealed.

Morphological integration refers to the interdependence of two or more phenotypic structures. The morphological integration concept is based on the fact that parts of complex organisms do not vary randomly and instead display degrees of non-independence that are thought to occur from shared genetic or developmental origins, and/or functional demands. Integrated traits may develop, evolve, and be inherited together. One instance of morphological integration can be found between the vertebral...
Show moreMorphological integration refers to the interdependence of two or more phenotypic structures. The morphological integration concept is based on the fact that parts of complex organisms do not vary randomly and instead display degrees of non-independence that are thought to occur from shared genetic or developmental origins, and/or functional demands. Integrated traits may develop, evolve, and be inherited together. One instance of morphological integration can be found between the vertebral column and the skull. Due to the position of the skull resting atop of the vertebral column, posture may influence skull development and overall craniofacial morphology. Morphological integration within or between structures is typically statistically assessed by exploring correlation and covariation patterns among biological structures of interest. In this study, an analysis of morphological integration was carried out by studying covariation of morphometric measures from the vertebral column and craniofacial complex. Age- and sex-matched, de-identified computed tomography images of individuals with kyphosis spinal malformation (n = 15) and controls (n = 19) were acquired from Florida Hospital. It is hypothesized that the sample of individuals with kyphosis will exhibit statistically significant covariance differences relative to the control group for T6 vertebral and midfacial linear distance measurements. Anatomical landmarks were identified on the T6 thoracic vertebrae (n = 6) and the midfacial skeleton (n = 6), and XYZ coordinates were recorded for analysis. A subset of 10 individuals (5 kyphosis, 5 controls) individuals were measured on two occasions to assess reliability and measurement error. An Euclidean Distance Matrix Analysis (EDMA) of morphological integration was carried out on the entire sample by calculating correlation values for paired linear distance measurements (one vertebral and one midfacial) separately for the kyphosis and control samples (n = 225 for each sample). Next, EDMA calculated correlation differences and statistically assessed significance using a non-parametric bootstrap (1,000 resamples) and confidence interval testing (? ? 0.10). Only 35 of the 225 (15.56%) correlation differences were statistically significant. Patterns of variation among these significant correlation differences were explored by examining sample directionality of differences, sign patterns, and strengths. The relevance of these results to clinical and anthropological pursuits are discussed. Several recommendations for future investigations are made.

Show morePopulation mean stature and patterns of health are often linked in anthropological studies, yet few studies control for the multifactorial nature of achieving adult standing height. This thesis explores the intersection of health and stature by analyzing the skeletal remains of 161 adult individuals from the archaeological site of Kuelap, in the eastern slopes of the northern Peruvian Andes, and also tests current biometric methods for estimating stature from skeletal remains. This Chachapoya site dates to the Late Intermediate Period (AD 900 (-) 1470) and Late Horizon (AD 1470 (-) 1536) and resides in the high altitude sub-tropical forests of the Andes. An anatomical method of stature estimation was applied to a subsample of 36 individuals and linear regression formulae were created, proving especially effective for the tibia and calcaneus in this sample. These new formulae produced more accurate results, regardless of sex, when compared to traditional estimates and suggest that sexually specific formulae are not necessary in studies of stature. However, sexual dimorphism in skeletal elements did produce an effective method of sex determination from individual appendicular elements and was tested successfully on commingled remains. This investigation produced valuable formulae for estimating both sex and stature from isolated remains in the Chachapoyas region. The results established that interregional variance in stature is consistent, but mean stature is strongly affected by environmental pressures. This study highlights the ineffectiveness of using stature to assess the relative health of geographically distinct populations, but demonstrates the possibility of culturally specific health interpretations. The formulae for sex and stature estimation created in this study have provided a glimpse of the intersection between culture, environment, and health in human biological diversity.

Show moreCeramic stamps are a rare, yet widely distributed, artifact class within ancient Mexico. However, there has only been limited scholarly research on these objects and much current research is minimally supported. Depicting a wide range of iconography, including metaphysical, floral, and faunal designs, the function and meaning of these stamps, also known as estampias, pintaderas, and sellos, in ancient Mexican life remain an archaeological mystery. This paper examines the contextual, chronological, and iconographic characteristics of ancient Mexican ceramic stamps as well as the distributional trends of those characteristics. This study is comprised of 83 stamps of varying design that date to between 1600 B.C.E. and 1520 C.E.: 19 found by the Rio Verde Project in Southern Oaxaca, Mexico, 5 found by Michael Coe in San Lorenzo, and 59 central Mexican stamps with credible, detailed provenience residing in the collection of the American Museum of Natural History and Robert S. Peabody Museum of Archaeology. Examined through the lens of culture history, processual, and postprocessual theory, comparative statistical analysis was conducted to assist the identification of significant trends. These analyses have revealed that stamp use shifted from mainly public to household spaces over time and that stamps predominantly depict nature and metaphysical themed motifs. I have also found that stamps were likely multipurpose artifacts whose use transcended social status. This research greatly expands on the limited literature about Mesoamerican ceramic stamps and provides valuable insight into ancient Mexican household, identity, and possibly religious, practices.

Show moreOne of the primary goals of biological anthropology is to develop an accurate understanding of human anatomy, health, disease, and injury in both modern and archaeological populations. Paleopathological analyses are a fruitful means of identifying disease and injury in skeletal assemblages, but the individual long-term biomechanical effects associated with pathological conditions have not yet been adequately explored in the literature. Leg fractures are a common pathological condition in both modern and archaeological populations, the effects of which may alter the biomechanics of gait. A growing body of clinical literature demonstrates that abnormal ambulatory function may have far-reaching effects in the rest of the body.To assess the long-term consequences of pathological conditions of the lower extremities, the relationship between lower limb long bone fracture occurrence, incidence of leg length disparity (LLD), and temporomandibular dysfunction (TMD) was analyzed. A total of 56 adult individuals (29 fractured, 27 unfractured) from the Hamann-Todd Osteological Collection (HTOC) at the Cleveland Museum of Natural History (curated between 1912 and 1938) were examined in this study. In total, the sample consisted of 37 males and 19 females (ages 25-76) of either black or white ancestry. LLD was assessed by taking standardized measurements of the lower limb long bones. TMD was analyzed by scoring the presence and severity of osteoarthritis of the temporomandibular joint (TMJ OA), dental attrition, and antemortem tooth loss. Kendall's Tau correlation statistics were used to assess morphological integration between all unique pairwise combinations of lower limb and jaw measurements among unfractured and fractured groups. Results indicate that several measures of LLD and jaw dysfunction are correlated differently in the unfractured and fractured groups. Comparisons of the All Unfractured and All Fractured groups most often showed higher absolute correlation values in unfractured individuals. Samples were also subdivided and compared based on known sex. Significant differences in patterns of morphological integration were observed between male and female sub-samples. Significant correlation values were almost always higher in the unfractured sample than in the fractured sample. Females, however, demonstrated both significant increases and significant decreases in absolute correlation values when comparing fractured and unfractured samples. Thus, patterns of significant differences in morphological integration between the lower limbs and jaw differ for males and females, with fairly consistent decreases in integration strength in the former and a mixed pattern of integration strength increases and decreases in the latter, when a leg fracture is involved. It is argued that these differences are explained by fundamental sexually dimorphic morphological and kinematic differences between males and females, such that fractures resulting in LLD affect the two sexes differently. Gendered lifetime social experiences and activity patterns may also explain the different male and female patterns identified in the analysis. These insights are applied to larger anthropological questions of social identity and the long-term injury experience.

Show moreIn forensic anthropology the estimation of biological sex of unidentified human remains is critical, as it essentially halves the number of potential identities. Sex estimation is also important in bioarchaeology, because the creation of the biological profile is critical to the interpretation of different sociocultural aspects of past populations. Furthermore, certain aspects of the biological profile are sex specific, so it is important to be able to accurately determine biological sex (France 1998). Typically, biological sex is estimated by assessing sexually dimorphic differences within the pelvis and skull. However, because sexually dimorphic differences arise during puberty it is difficult, and oftentimes impossible, to use these traditional techniques on juveniles. Recently, human hair has gained prominence in anthropological research. This is particularly evident in bioarchaeology, where hair can be used to discern information concerning health, toxicology, culture, and diet of past populations. This study focuses on the relationship between the content of trace elements in hair and biological sex to determine if biological sex can be assessed from the content of trace elements in human head hair. Hair was collected from three human sample groups: modern living individuals, modern cadavers, and archaeological remains. Data on trace elements was collected using laser-induced breakdown spectroscopy (LIBS). The statistical relationship between the content of trace elements and sex was then analyzed using a multivariate analysis of variance (MANOVA), post-hoc analysis of variance (ANOVAs), and stepwise binary logistic regression. The MANOVA revealed a statistically significant multivariate main effect for sample group using mean values (p-value (<) 0.0001) and mean variance values (MVs) (p-value = 0.018). Given the significant results of the MANOVA test, the univariate main effects were examined with post-hoc ANOVA tests. Significant univariate main effects were obtained for mean values for C/Mg (p-value (<) 0.0001), C/Fe (p-value (<) 0.0001), C/Ca (p-value (<) 0.0001), and C/Sr (p-value (<) 0.0001). Significant univariate main effects were obtained for MVs for C/Mg (p-value = 0.016), C/Fe (p-value = 0.010), and C/Sr (p-value = 0.042). These preliminary results demonstrate that biological sex of humans can be accurately estimated through trace elemental analysis approximately 85% of the time in living samples, and 79% of the time overall. The results also demonstrate the viability of this technique for sex estimation in juvenile remains with approximately 83% success in predicting juvenile biological sex. This sets the stage establishing trace elemental analysis of hair as a technique for estimating biological sex which is critical to forensic individuation and identification as well as further contextualization of archaeological remains.

Show moreTampa Bay and the broader Central Gulf Coast region of Florida bear evidence of site reduction and population decline during the onset of the Late Woodland period (AD 500-1000). Concomitantly, Weeden Island culture flourished to the north, while climatic instability loomed to the south. It is unclear if the site abandonments in the area between the two are related to social or cultural change, an unstable climate, or a combination thereof. Interdisciplinary research has provided evidence for climate change and sea level regression during the sixth and seventh centuries in Southwest Florida, but these variables have yet to be investigated in Tampa Bay. This study implements a multi-scalar sclerochronological analysis to better understand how the climate of Tampa Bay has changed through time. Analyses of low-resolution stable isotopes (13C and 18O) paired with high-resolution trace elements (Mg, Na, Li, Sr) from 50 eastern oyster (Crassostrea virginica) specimens supports climatic instability during the Late Woodland period in Tampa Bay.
