Evolutionary models of clonal expansion and niche construction
(2022-05-11)Heart disease and cancer, the two leading causes of death in the industrialized world, are linked to expansions of clonal cell populations in the body, driven by the evolutionary processes of mutation, selection, drift, ... -
Evolutionary Novelty in a Butterfly Wing Pattern through Enhancer Shuffling
(Public Library of Science (PLoS), 2016)An important goal in evolutionary biology is to understand the genetic changes underlying novel morphological structures. We investigated the origins of a complex wing pattern found among Amazonian Heliconius butterflies. ... -
Evolutionary Origins of Gondwanan Interactions: How Old Are Araucaria Beetle Herbivores?
(Oxford University Press (OUP), 2001-12)Studies of a variety of phenomena, ranging from rates of molecular substitution to rates of diversification, draw on estimates of geological age. Studies incorporating estimates of timing from fossils or other geological ... -
The Evolutionary Origins of Human Patience: Temporal Preferences in Chimpanzees, Bonobos, and Human Adults
(Cell Press, 2007)To make adaptive choices, individuals must sometimes exhibit patience, forgoing immediate benefits to acquire more valuable future rewards. Although humans account for future consequences when making temporal decisions, ... -
Evolutionary Origins of the Endowment Effect: Evidence from Hunter-Gatherers
(American Economic Association, 2014)The endowment effect, the tendency to value possessions more than non-possessions, is a well known departure from rational choice and has been replicated in numerous settings. We investigate the universality of the endowment ... -
An evolutionary perspective on germ cell specification genes in insects
(2014-06-06)This dissertation investigates the embryonic specification of a specific group of cells: the germ cells. Germ cells, which give rise to sperm and egg, are the only cells in sexually-reproducing animals that directly ... -
Evolutionary Perspectives on Pregnancy

Evolutionary principles of modular gene regulation in yeasts
(eLife Sciences Publications, Ltd, 2013)Divergence in gene regulation can play a major role in evolution. Here, we used a phylogenetic framework to measure mRNA profiles in 15 yeast species from the phylum Ascomycota and reconstruct the evolution of their modular ... -
Evolutionary Radiation of an Inbreeding Haplodiploid Beetle Lineage (Curculionidae, Scolytinae)
(Oxford University Press (OUP), 2000-11) -
The Evolutionary Social Psychology of Off-record Indirect Speech Acts
(Walter de Gruyter, 2007)This paper proposes a new analysis of indirect speech in the framework of game theory, social psychology, and evolutionary psychology. It builds on the theory of Grice, which tries to ground indirect speech in pure rationality ... -
Evolutionary Stability on Graphs
(Elsevier, 2008)Evolutionary stability is a fundamental concept in evolutionary game theory. A strategy is called an evolutionarily stable strategy (ESS), if its monomorphic population rejects the invasion of any other mutant strategy. ... -
Evolutionary stasis and lability in thermal physiology in a group of tropical lizards
(The Royal Society, 2014)Understanding how quickly physiological traits evolve is a topic of great interest, particularly in the context of how organisms can adapt in response to climate warming. Adjustment to novel thermal habitats may occur ... -
Evolutionary Trajectories and Biogeochemical Impacts of Marine Eukaryotic Phytoplankton
(Annual Reviews, Inc., 2004)The evolutionary succession of marine photoautotrophs began with the origin of photosynthesis in the Archean Eon, perhaps as early as 3.8 billion years ago. Since that time, Earth's atmosphere, continents, and oceans have ... -
Evolutionary Yarns in Seahorse Valley: Living Tissues, Wooly Textiles, Theoretical Biologies
(Duke University Press, 2013)The Hyperbolic Crochet Coral Reef (HCCR) is a distributed venture of thousands of women who cooperatively fabricate a collection of yarn and plastic coral reefs. Under the auspices of the Institute For Figuring, these ... -
Evolutions of fault damage zones and consequences for earthquake triggering
(2021-05-14)Studying the interactions between underground fluid and faults is crucial to help us understand the earthquakes which occur at relatively low driving stresses. In this thesis, I investigate the permeability evolution in ... -
Evolvability
(Association of Computing Machinery, 2009)Living organisms function in accordance with complex mechanisms that operate in different ways depending on conditions. Darwin's theory of evolution suggests that such mechanisms evolved through variation guided by natural ... -
Evolving a Direct Inhibitor of the Ras Proteins
(2013-08-12)In recent years, great advances have been made in understanding the molecular causes of human disease, but our ability to exploit these discoveries for therapeutic benefit is frequently limited by the inability to make ... -
Evolving Line Drawings
(1993)This paper explores the application of interactive genetic algorithms to the creation of line drawings. We have built a system that starts with a collection of drawings that are either randomly generated or input by the ... -
Evolving Models of Ovarian Cancer: Defining the Role of PAX8 in Fallopian Tube Tumorigenesis
(2015-08-07)Ovarian cancer is the most deadly gynecological malignancy in the US. Once thought to be a single disease arising from the ovarian surface epithelium, we now understand that it is in fact a heterogenous disease with origins ... -
Evolving Righteousness in a Corrupt World
(Public Library of Science, 2012)Punishment offers a powerful mechanism for the maintenance of cooperation in human and animal societies, but the maintenance of costly punishment itself remains problematic. Game theory has shown that corruption, where ...
