Evolutionary dynamics of the hominin pelvis
… genetic theory and methods to the study of hominin pelvic evolution. There are three sets of results. First, stepping back from paleoanthropological issues, this study explores the effects of sample size and transformations on the statistics that form the backbone of the analyses to follow. …

Patterns of Archaic Hominin DNA in Modern Human Genomes
… of introgression from an unknown archaic hominin with an apparent divergence time with modern humans that is similar to the divergence time of Neanderthals. In a sample of 379 European and 279 East Asian genomes, I identify on average 1/4 of each individual's introgressed Neanderthal …

Using multivariate calibration to evaluate hominin brain/body size relationships
… methods that increase the sample size of fossil hominins, provide more confidence in body mass estimates, and allow a comparison of the rate and timing of changes in each trait over the past 4+ million years (mya). Brains and bodies show different evolutionary patterns over time. Body size …

Genetic inference of deep hominin evolutionary history using the sequentially Markovian coalescent
Whole genome sequencing has allowed researchers to infer human demographic history with unprecedented resolution. Of particular interest are the series of population size changes, admixture events, and adaptations that have occurred over time. Many methods that infer these quantities rely on …

Functional myology of the primate head and neck with implications for hominin evolution
… of fossil primates, particularly fossil hominins, have relied upon untested hypotheses linking nuchal muscle form and function to bony morphologies. This thesis addresses the gap in knowledge of variation in the primate nuchal musculature and its relationship to positional behaviors …

A comparison of statistical and geometric reconstruction techniques : guidelines for correcting fossil hominin crania
The study of human evolution centres, to a large extent, around the study of fossil morphology, including the comparison and interpretation of these remains within the context of what is known about morphological variation within living species. However, many fossils suffer from environmentally …

Hominin cognitive and behavioural complexity in the Pleistocene: assessment through identity, intentionality and visual display
… Hypothesis predicts the cognitive ability of hominin species by utilising estimated brain and group sizes in relation to an ordinal scale of cognitive complexity expressed as orders of intentionality. The Social Brain Hypothesis predictions however, have never been correlated to the …

The palaeolithic of the Avon valley: a geoarchaeological approach to the hominin colonisation of Britain.
… Their contribution to the understanding of hominin presence and behaviour in northwest Europe has though remained largely obscured due to the complex depositional context of Pleistocene fluvial terraces and limited age constraints of these sites. This thesis discusses the current knowledge …

Effects of Instrumentation on Dental Microwear Textures: Reanalysis and Augmentation of an Early Hominin Sample
… patterning. The first study examines a sample of hominin molars (Australopithecus africanus and Paranthropus robustus) for comparison with data previously scanned and analyzed on the University of Arkansas' Plu Standard confocal microscope (Scott et al., 2005). The second study expands the sample …

Diagnosing Bone Fracture to Assess Early Hominin Behaviour, Meat-Eating, and Socioecology at FLK-Zinjanthropus, Olduvai Gorge, Tanzania
… This is important because interpretations of hominin entry into the carnivore guild and evolution of meat-eating are based on rare tool and tooth marks in Oldowan (2.5-1.8mya) fossil assemblages. Consequently, estimating hominin and carnivore involvement is difficult, and questions remain …

How did the Human Brain Evolve? Tracking Cerebral Changes in the Fossil Hominin Record Using Advanced Imaging Techniques and 3D Modelling
Understanding the evolution of the hominin brain is critical for reconstructing the emergence of human cognitive abilities. However, given the lack of direct fossilised brain tissue, palaeoneurological studies rely on cranial endocasts, replicas of the internal surface of the braincase, to infer …

Of mice and hominins: using the craniomandibular morphology of hybrid mice to better understand hybrid morphologies in the Hominin fossil record
… research into hybridization and gene flow among hominin taxa in the Late Pleistocene. However, little research has focussed on how hybridization affects skeletal morphology. In regions and time periods where the recovery of ancient DNA is not possible, a thorough understanding of hybrid …

The Makapansgat Hominins: A Descriptive and Comparative Morphological Study
… the assemblage to other South African early hominin samples. The fossils examined here include previously undescribed fossils from the fossiliferous ex-situ breccia piles of the Makapansgat Limeworks. Data analyses incorporated extant humans, gorillas, chimpanzees, and macaques to provide a …

Dietary ecology of mixed-feeding antelopes in the Omo-Turkana basin during the Plio-Pleistocene: a tool to investigate hominin palaeo-environments.
… antelope species could be used to investigate hominin palaeo-environments in the Omo-Turkana basin during the Plio-Pleistocene (3.5-1.6 Ma), a detailed study of the dietary ecology of mixed-feeding antelopes was proposed. This research focused on the diets of the impala (genus Aepyceros) and …

Using a multiproxy analysis of springbok fossils to track 2 million years of vegetation changes experienced by hominins in southern Africa.
A causal link between climatic changes and hominin evolution is an established one, yet the exact dynamics of this relationship is debated. Key climatic changes, such as the intensification of the Northern Hemisphere Glaciation, the onset of the Walker Circulation and the Mid-Pleistocene …

Paranthropus paradoxes: Patterns of morphological variation in East African 'robust australopithecines'
… Paranthropus represents an iconic taxon in the hominin fossil record. Its early discovery, together with its morphological distinctiveness, have defined this genus as a unique hominin lineage parallel to our own. Paranthropus boisei, who lived in East Africa between 2.3 and 1.4 million years …

Landscapes of the apes: modelling landscape use of chimpanzees and early hominins across an environmental gradient.
… role in human evolution, but evidence on early hominin behaviour remains limited. Chimpanzee responses to changing landscapes may provide new insights into early hominin landscape use due to chimpanzees’ close relatedness to humans. This thesis used individual-based and referential modelling to …
