Evolution Of Lactate Dehydrogenase Genes In Primates, With Special Consideration Of Nucleotide Organization In Mammalian Promoters
… to the brain increased during stem anthropoid evolution, leading to humans. One mechanism by which this allocation may have occurred is through greater use of lactate as a neuronal fuel. Both the production of lactate, and conversion to pyruvate for use in aerobic metabolism, are catalyzed, in …

Evolution of Gene Regulation in Papio Baboons
… are thought to play an important role in primate evolution and divergence. In support of this hypothesis, comparative evidence clearly demonstrate that gene expression patterns differ between closely related species and tend to evolve under selective constraint. However, we know little …

Sistemática filogenética dos primatas do novo mundo e a evolução do aparelho mastigatório (Platyrrhini, Primates)
Studied the evolution of the masticatory apparatus of the New World monkeys as part of a broader cladistic research program on primate evolution. All the 16 currently recognized extant genera currently plus 4 fossil taxa were investigated. The information content in this morphological complex is …

The human Deleted in Azoospermia gene family : structure, function and evolution
… and male infertility. This thesis describes the evolution, structure and function of human DAZ genes. First, we determined that Y-linked DAZ genes arose by transposition from an autosomal ancestor during primate evolution, and were repeatedly amplified and pruned by multiple splicing mutations. …

Alu retrotransposition-mediated genomic variation within the primate order
… are an active family of mobile elements within primate genomes and the Short INterspersed Element (SINE) Alu is the most abundant member. These non-autonomous elements are responsible for introducing genomic diversity on an intra- and inter- species level that is useful in studies of forensic …

Predictors, Costs, and Consequences of Larval Tapeworm Infection in Geladas (Theropithecus gelada).
<p>Parasitism is integral to primate evolution, contributing to major life history tradeoffs with other processes critical to reproductive success and survival. I investigate how infection with the tapeworm Taenia serialis affects geladas (Theropithecus gelada) in the Simien Mountains National …

The gut microbiome of the western lowland gorilla (Gorilla gorilla gorilla): implications for overall ecology
Our closest evolutionary relatives, non-human primates, display a breadth of behavioral, anatomical and physiological adaptations, which allow them to exploit a myriad of habitats. Detailed representation of these adaptive tools has constituted the basis of our knowledge of primate ecology and …

HUMAN GENOME VARIATIONS AND EVOLUTION WITH A FOCUS ON THE ANALYSIS OF TRANSPOSABLE ELEMENTS
… variants among individuals. In this thesis, the evolution and functional impact of structural variations is examined primarily focusing on retrotransposons in the context of human evolution. The thesis comprises of three different studies on the topics that are presented in three data chapters. …

Retrotransposon mediated genomic fluidity in the human and chimpanzee lineages
… Although they are abundant throughout primate genomes, their propagation strategy remains poorly understood. The recently released human and chimpanzee draft genome sequences provide the opportunity to compare the human genome with the chimpanzee genome. Thus, we were able to assess how …

Endocranial volume and shape variation in early anthropoid evolution
<p>Fossil taxa are crucial to studies of brain evolution, as they allow us to identify evolutionary trends in relative brain size and brain shape that may not otherwise be identifiable in comparative studies using only extant taxa, owing to multiple events of parallel encephalization among primate …

Evolution of Nuclear Integrations of the Mitochondrial Genome in Great Apes and their Potential as Molecular Markers
… study aimed to systematically compare the evolutionary dynamics of MCR numts in great apes. Firstly, an inventory numts derived from the region containing the MCR subdomains was carried out by genomic BLAST searches. Secondly, presence/absence of each candidate numt was determined in great …

Evolution of the Hominoid Vertebral Column
… 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 similarity by common …

Novel proapoptotic p63 isoforms are driven by an endogenous retrovirus in the male germ line of humans and great apes, likely increasing genome stability
… retrovirale Integration sich sehr spät in der Evolution, vor ungefähr 15 Millionen Jahren, ereignete. Das entsprechende Protein ist das einzige p63-Protein in humanem testikulären Lysat, das in verschiedenen männlichen Keimzellen mit Hilfe von Immunhistochemie detektiert wurde. Während dieses …

The role of modularity and integration in shaping primate pelvic girdle evolution
… of integrated units) on the morphological evolution of the primate pelvis. The concepts of integration and modularity are core tenets of evolutionary biology, yet their evolutionary role remains poorly understood. In this thesis, I quantified primate pelvis morphological variation across 4 …
