A Computational Synthesis of Genes, Behavior, and Evolution Provides Insights into the Molecular Basis of Vocal Learning
(2012)Vocal learning is the ability modify vocal output based on auditory input and is the basis of human speech acquisition. It is shared by few distantly related bird and mammal orders, and is thus very likely to be an example ... -
A Mechanical Analysis of Suspensory Locomotion in Primates and Other Mammals
(2016)For primates, and other arboreal mammals, adopting suspensory locomotion represents one of the strategies an animal can use to prevent toppling off a thin support during arboreal movement and foraging. While numerous studies ... -
Culture From Infrahumans to Humans: Essays in the Philosophy of Biology
(2007-05-07)It has become increasingly common to explain the behavior of animals—from sperm whales to songbirds—in terms of culture. But what is animal culture, what is its relationship to other biological concepts and to human culture, ... -
Evolutionary Implications and Genetic Basis of Peroxide Survival in Saccharomyces Cerevisiae
(2009)Hydrogen peroxide is used by animals and plants to deter the growth of microbial invaders by inflicting DNA lesions, protein oxidation and lipid membrane modifications. Pathogens protect themselves with enzymes and scavenging ... -
Genomic, Genetic, and Functional Interrogation of Mycobacterium tuberculosis Outbreak Strains
(2017)In the past 200 years, tuberculosis (TB) has caused more deaths than any other infectious disease and currently infects more people than it has at any other time in human history. Mycobacterium tuberculosis (Mtb), the etiological ... -
How Evolution, Stories, and Irrationality Influence Decision Making in Financial Markets: Analyzing Whether We Can Leverage Our Innate Traits and Heuristics to Improve Outcomes
(2020-12-13)One of the most commonly asked questions in investing is whether or not it is possible to achieve excess returns in the financial markets. To give a somewhat simple answer, for most investors a basic low-fee passive ("static") ... -
Positive selection within the genomes of SARS-CoV-2 and other Coronaviruses independent of impact on protein function.
(PeerJ, 2020-01)Background:The emergence of a novel coronavirus (SARS-CoV-2) associated with severe acute respiratory disease (COVID-19) has prompted efforts to understand the genetic basis for its unique characteristics and its jump from ... -
Scoring Evolution and Creationism
(2011-12)From 2002 to 2006, Cobb County, Georgia placed controversial stickers on high school biology textbooks which were critical of evolution. This study uses the differences-in-differences method to analyze what effects the ... -
Selection and Constraint: Population Genetic Approaches to Understanding the Evolution of Sea Urchin Development
(2011)Changes in the expression and function of genes active during metazoan development have played a critical role in the evolution of morphological differences between species and phyla, yet the origins of these changes remain ... -
Stochastic Dynamics and Epigenetic Regulation of Gene Expression: from Stimulus Response to Evolutionary Adaptation
(2016)How organisms adapt and survive in continuously fluctuating environments is a central question of evolutionary biology. Additionally, organisms have to deal with the inherent stochasticity in all cellular processes. The ... -
Studies into Location-specific cis-Regulatory Motifs
(2010)Gene expression and regulation are major determinants of phenotypic traits displayed across species. Although the DNA sequence elements that control gene expression play a crucial role in determining species morphology, ... -
The Evolution and Genetics of Reinforcement in Phlox Drummondii
(2010)One of the major goals of evolutionary biology is understanding the process of species formation. There is particular interest in how selection can favor species formation through the process of reinforcement. When two ... -
The Evolution of the Glucosinolate Pathway in the Brassicaceae
(2013)Understanding the mechanisms that underlie the formation of, and innovation in biochemical pathways is an important goal in evolutionary biology. The following work addresses the problem of biochemical pathway evolution ... -
The Role of Polyploidy in Phenotypic and Genomic Evolution in the Shy Monkeyflower, <i>Mimulus sookensis<i>
(2012)In an ever-changing world, evolution is an essential process that may allow organisms to adapt to their environment through natural selection. All evolutionary processes act through a single fundamental medium: genetic variation. ... -
Two Antarctic penguin genomes reveal insights into their evolutionary history and molecular changes related to the Antarctic environment.
(Gigascience, 2014)BACKGROUND: Penguins are flightless aquatic birds widely distributed in the Southern Hemisphere. The distinctive morphological and physiological features of penguins allow them to live an aquatic life, and some of them have ... -
Unisexual Reproduction in Cryptococcus: Evolutionary Implications, Virulence and RNA Silencing
(2013)Sexual development enables microbial pathogens to purge deleterious mutations from the genome and drives genetic diversity in the population. <italic>Cryptococcus neoformans</italic> is a human fungal pathogen with a defined ...
