Genetic Analysis of Taste in Homo Sapiens
There are many known taste receptors specific to each taste attribute. This thesis examines the relationship between single nucleotide polymorphisms (SNPs) and copy number variations (CNVs) in known taste and taste pathway receptors TAS2R38, Gustin, and TRPM5 and for PROP (6-n-propylthiouracil) …

Ecomorphological and Ecometric Approaches to Clarifying Homo sapiens Palaeoecology
… and genetic evidence suggest that the origins of Homo sapiens lie somewhere in Africa during the late-Early to Middle Pleistocene period (~1,000,000-500,000 years ago). The morphological diversity of hominin fossils, the patterns seen in technological and cultural evolution, and the signals of …

Comparative Analysis of Alternative Splicing in Homo sapiens, Mus musculus and Rattus norvegicus Transcriptomes
… spliced transcripts in transcriptomes of Homo sapiens, Mus musculus and Rattus norvegicns. Our databases allow in-depth analyses of alternative and constitutive exons within alternatively spliced genes. Interactive web implementation of our databases brings to end-users the ability to …

Characterization of Leucyl -Trna Synthetase From Homo Sapiens and Escherichia Coli in Aminoacylation, Amino Acid Editing and Interdomain Interactions
"Human cytoplasmic LeuRS (hscLeuRS) is typically found in a macromolecular complex containing at least eight other proteins. In order to study this enzyme, hscLeuRS was expressed independent of the complex in Escherichia coli. Enzymatic characterization of the isolated hscLeuRS suggested that it …

Characterization of leucyl-TRNA synthetase from homo sapiens and escherichia coli in aminoacylation, amino acid editing and interdomain interactions
Aminoacyl-tRNA synthetases (aaRSs) are ancient enzymes that charge tRNA with its cognate amino acid. In order to maintain fidelity during protein synthesis, editing mechanisms ensure that tRNAs are accurately charged. Leucyl-tRNA synthetase (LeuRS) has an editing active site that resides in a …

Functional adaptation of mandibular trabecular bone and its association with diet: Inter- and intra-specific comparisons among Homo sapiens, papionins, and mice.
Mandibular cortical bone morphology varies considerably across mammals and has been attributed to changes in feeding behaviour related to diet, subsistence and food mechanical properties (FMPs), including the shift from hunter-gathering to agriculture within humans during the Neolithic. Trabecular …

In the human past, is the perennial consumption of starch a deep or shallow phenomenon?
… by genetic and biological evidence that Homo sapiens was especially adapted to a starch diet within the Palaeolithic, making starch consumption a deep phenomenon. Yet there is no deep time archaeological evidence of starch consumption by early humans. A significant body of evidence …

Later Quaternary archaeological sequences in northern Tanzania
… of the age and cultural associations of archaic Homo sapiens remains, the Eyasi crania, which are older than 150,000 years bp. A standardized typology was formulated and is applied to all lithic assemblages. Results indicate that a Sangoan Industry is associated with archaic Homo sapiens. The …

Web servers, databases, and algorithms for the analysis of protein interaction networks
… proteome-wide pre-computed PPI predictions for Homo sapiens, Drosophila melanogaster, and Saccharomyces cerevisiae. 2. Comparative analysis of PPI networks across organisms can provide valuable insights into evolutionary conservation. We describe an algorithm, called IsoRank, for global …

The Cochlear Labyrinth of Krapina Neandertals
… cochlear volumes are similar to modern Homo sapiens and larger than chimpanzee and gorilla cochlear volumes. Although the nature of the relationship between cochlear volume and hearing abilities remains speculative, the measured cochlear volume in Krapina Neandertals suggests they had a …

Socially Motivated Vocal Learning
… vocal learning in two social species, humans (Homo sapiens sapiens) and an oscine songbird, the zebra finch (Taeniopygia guttata). Using both behavioral and neuroanatomical data, Chapter 2 of this thesis argues that both the evolution and the development of vocal learning were triggered by the …

The Genetic Structure of the Kuwaiti and Failaka Island Populations: Y-chromosome & Mitochondrial DNA Variation

The Arabian Peninsula is connected to three continents: Africa, Asia, and Europe. In addition to the major diaspora, the Arabian Peninsula has witnessed …

The impact of yesterday’s territorial shortages on today’s adapted mind
… punctuated much of human evolutionary history, homo sapiens are endowed with an evolved psychological mechanism (EPM) to view threats concerning territory as especially salient and worthy of aggressive retorts. I go on to contend that variation in individuals’ ontogenetic contexts—such as sex …
