Human population history and its interplay with natural selection
… thesis, I aimed to refine our knowledge on human population history using ancient genomes, and then used a climate-informed, spatially explicit framework to explore the interplay between complex demographies and selection. I first analysed a high-coverage genome from Upper Palaeolithic Romania …

Human population history and genetic adaptation in the Himalayan region
… functional studies to explore the demographic history, genetic structure and signatures of adaptation in Himalayan populations. Eight hundred and eighty three individuals from 49 different autochthonous groups from Nepal, Bhutan, North India, and the Tibetan Plateau in China were genotyped for …

Genomic insights into the human population history of Australia and New Guinea
… the importance of this part of the world to the history of humanity outside Africa, little is known about the population history of the people living here. In this thesis I present population-genetic studies using whole-genome sequencing and genotype array datasets from more than 500 indigenous …

Unraveling the population history of the Xiongnu to explain molecular and archaeological models of prehistoric Mongolia
<p>This dissertation explores the prehistory of Mongolia during a time when nomadic tribes created the world's first steppe empire in Inner Asia. These aggregated tribes, known to Chinese historians as Xiongnu, ruled from the 3rd century BCE to the 2nd century CE. They came to define steppe polity …

The Effect of Population History on Hominoid Intraspecific Cranial Shape Diversity: Combining Population Genetic and 3D Geometric Morphometric Data
… than twice that of all living humans. Here, the population history of each species, or sub-species, is considered as a force potentially structuring phenotypic variation. It is already well established that population history has shaped patterns of modern human cranial diversity across the world. …

Dental Variation in Central Mexican Latinx Individuals
… of this dissertation was to explore the population history of a Central Mexican Latinx sample through dental morphological variables and odontometric crown and cervical measurements. Biological distance, or biodistance statistics, fuzzy c-means analyses, and linear discriminant function …

The Bioarchaeology of An Sơn and Hòa Diêm: Biosocial Insights into Prehistoric Southern Vietnam
… modifications and palaeodiet, four metathemes of population history, connectivity, the Neolithic Demographic Transition and the osteological paradox were developed as a conceptual framework in which to explore these health indicators. The population affinities of both An Sơn and Hòa Diêm support …

Insights into the genomic histories of diverse human populations using whole-genome sequencing analysis.
Despite the progress in sampling many populations, human genomics research is still not fully reflective of the diversity found globally. Understudied populations limit our knowledge of genetic variation and population history, and their inclusion is needed to ensure they benefit from future …

Historical refuges and recolonization routes in the Southern Appalachian Mountains, inferred through phylogeographic analysis of the spotted wintergreen (Chimaphila maculata)
… modeling to test competing scenarios of population history of a species. Ecological niche modeling has also been useful in inferring areas of likely suitable habitat during past climate conditions. Several studies have examined the population history of biota in the Southern Appalachian …

Lack of polymorphism suggests a recent bottleneck of Aloidendron pillansii: Exploration into the population of Aloidendron pillansii from phylogeographical analysis of molecular data
… are found, such as Aloe pillansii. The recent population history of A.pillansii is poorly understood. However the suggested climatic shifts that occurred throughout the Holocene era may have affected its distribution, demographics and gene flow. The glacial/interglacial refugia hypothesis …

Mitochondrial DNA in ancient human populations of Europe.
… of thousand years of human evolutionary and population history. Geographical variation in the nonrecombining maternally inherited mitochondrial DNA has been studied in a wide array of modern populations in order to reconstruct the migrations that have participated in the spread of our …

Using ancient DNA to infer impacts of European colonization on first nations populations in coastal British Columbia, Canada
… partnered with the Malhi lab to explore their population history and the genetic effects of colonization on BC First Nations populations. In this dissertation, I sequenced the hypervariable segment (HVS1) of mitochondrial DNA (mtDNA) of 61 ancient PRH individuals and compared them to the …

Efficient haplotyping for families
… gene conversions. They can also be used to study population history, including expansion, contraction, and migration patterns in humans and other species. Hapi's efficiency is a result of eliminating or ignoring states and state transitions that are unnecessary for computing haplotypes. When …

Graphs, matrices, and populations : linear algebraic techniques in theoretical computer science and population genetics
… we consider the problem of inferring human population history from genetic data. We give an efficient and principled algorithm for using single nucleotide polymorphism (SNP) data to infer admixture history of various populations, and apply it to show that Europeans have evidence of mixture …

Patterns of linkage disequilibrium in the human genome
… LD is relatively simple. Over the lifetime of a population, the genetic markers that are adjacent to an ancestral mutation will recombine less often than more distant markers. Therefore, the ancestral alleles of the markers closest to the mutation should be most frequent in a collection of …

Craniofacial morphology and the consequences of intentional cranial deformation among prehistoric Andean populations
… conflicting interpretations of Azapa valley population history. Distances calculated using new measurements suggested general continuity, while distances calculated using old measurements indicated early isolation and late interaction. This discrepancy may be ascribed to the older …
