Evolution of the Hominoid Vertebral Column
… role in locomotion and posture. Recent models of hominoid vertebral evolution invoke very different roles for homology and homoplasy in the evolution of vertebral formulae in living and extinct hominoids. These processes are fundamental to the emergence of morphological structures and reflect …

Bilateral Asymmetry in Incisors: Implications for Miocene Hominoid Species Diagnosis
… ASYMMETRY IN INCISORS: IMPLICATIONS FOR MIOCENE HOMINOID SPECIES DIAGNOSIS MAJOR PROFESSOR: Dr. Robert S. Corruccini The primary purpose of this dissertation is to show how knowledge of variation and asymmetry in incisor antimeric pairs of living great ape genera can be utilized as a "yardstick" …

Eurasian Middle and Late Miocene Hominoid Paleobiogeography and the Geographic Origins of the Homininae
The origin and diversification of great apes and humans is among the most researched and debated series of events in the evolutionary history of the Primates. A fundamental part of understanding these events involves reconstructing paleoenvironmental and paleogeographic patterns in the Eurasian …

The Effect of Population History on Hominoid Intraspecific Cranial Shape Diversity: Combining Population Genetic and 3D Geometric Morphometric Data
<p>Cranial shape diversity within hominoids has been previously studied with the aim of understanding how levels of diversity in extant species compare with extinct hominin specimens. This dissertation addresses the question of why cranial shape diversity differs among extant hominoids. Levels of …

Comparative population genetics of the Hominoidea: An investigation of locus-specific and genome-wide influences
… across the four genomic compartments in the Hominoidea (humans, chimpanzees, bonobos, gorillas, and orangutans) in order to test the hypothesis that a high variance in male reproductive success, as predicted from behavioral data, may influence levels of hominoid genetic diversity. First, …

A morphometric study of cranial shape in the Hominoidea
… description to the problem of defining hominoid cranial form. The aim has been to produce an objective assessment of the relative merits of the methods from both a practical and theoretical perspective. The thesis is presented in three parts. In the first, several approaches which offer …

Comparative analysis of primate hydrogenotrophic microbiota
… smithii, was detected in all captive hominoid species, indicating high similarity of methanogenic microbiota among these primates and humans. Comparison of wild and captive primates indicated that captive condition can be a major determinant of hydrogenotrophic microbial composition …

Functional morphology of mammalian sacra and caudal vertebrae : implications for tail loss and positional behaviors in extinct primates
All living hominoids are characterized by taillessness and adaptations to orthograde (upright) trunk posture. Accordingly, these features have importance for our understanding of ape origins, evolutionary relationships and positional behaviors. Despite extensive study of the hominoid postcranial …

The Ape Ecological Niche: Posture and Hand Use in Gibbons and Macaques and the Influence of Manual Skill on Cognitive Development in Apes and Humans
… patterning indicating there is a distinctively hominoid brain structure. These features in great apes have consistently been linked with higher cognitive skills and are considered to be the precursors leading to the exceptional developments of humans over evolutionary time – establishing …

Retrotransposon-mediated instability in the human genome
… alignment of the human genome with two other hominoid genomes allows human lineage-specific changes (i.e., those younger than 5-6 million years) to be accurately dissected out. Here, using a combined computational and experimental approach, we have attempted to provide an unbiased picture of …

Digestive Strategies, Fruit Processing, and Seed Dispersal in the Chimpanzees (Pan Troglodytes) and Redtail Monkeys (Cercopithecus Ascanius) of Kibale National Park, Uganda
… carbohydrates more effectively than their hominoid counterparts. I discuss that this capacity may have given early cercopithecines a competitive advantage during periods of diminishing resources and may help explain the adaptive radiation of the Cercopithecinae beginning in the late Miocene.

Assessing primate skull shape variation in relation to habitat: a 3D geometric morphometric approach
… variation patterning and, therefore, consolidate hominoid systematic procedures. This thesis identifies ecomorphological patterns of variation within extant primates. Through a comparative, multivariate and geometric morphometric approach, this research provides a better understanding of the …

Evolutionary dynamics of the hominin pelvis
… dimensions in later hominins reduced ancestral hominoid genetic constraints on the birth canal, allowing for morphological evolution along a trajectory that might have previously been difficult or impossible to traverse. In total, the results presented here suggest that natural selection led to …

Chromosomes and spermatozoa of the great apes and man
… man and gorilla than between man and the other hominoid apes. Moreover, the heteromorphism of spermatozoa in both human and gorilla semen samples makes it unlikely that clothing induced hyperthermia is the cause of pleiomorphic spermatozoa in man.
