Abstract:
Experimental evolution is a powerful approach that can be used for the study of adaptation. Evolutionary biologists often use Drosophila as a model organism in experiments that test theories about the evolution of traits related to fitness. Such evolution experiments can take three forms: direct selection for a trait of interest; surveys of traits of interest in populations selected for other traits; and reverse selection. We review some of the Drosophila experiments that have provided insight into both the evolution of particular physiological traits and the correlations between physiological

Abstract:
In the classic view introduced by R. A. Fisher, a quantitative trait is encoded by many loci with small, additive effects. Recent advances in quantitative trait loci mapping have begun to elucidate the genetic architectures underlying vast numbers of phenotypes across diverse taxa, producing observations that sometimes contrast with Fisher's blueprint. Despite these considerable empirical efforts to map the genetic determinants of traits, it remains poorly understood how the genetic architecture of a trait should evolve, or how it depends on the selection pressures on the trait.

Abstract:
Although evolution by natural selection is widely regarded as the most important principle of biology, it is unknown whether phenotypic variations within and between species are mostly adaptive or neutral due to the lack of relevant studies of large, unbiased samples of phenotypic traits. Here, we examine 210 yeast morphological traits chosen because of experimental feasibility irrespective of their potential adaptive values. Our analysis is based on the premise that, under neutrality, the rate of phenotypic evolution measured in the unit of mutational size declines as the trait becomes more i

Phylogenetic comparative methods (PCMs) provide a potentially powerful toolkit for testing hypotheses about cultural evolution.

We found that the mode of horizontal transmission of traits has important consequences for both methods. Where traits were horizontally transmitted separately , PCMs accurately reported when trait evolution was not correlated even at the highest levels of

Abstract:
Function-valued traits—phenotypes whose expression depends on a continuous index (such as age, temperature, or space)—occur throughout biology and, like any trait, it is important to understand how they vary and evolve. Although methods for analyzing variation and evolution of function-valued traits are well developed, they have been underutilized by evolutionists, especially those who study natural populations. We seek to summarize advances in the study of function-valued traits and to make their analyses more approachable and accessible to biologists who could benefit greatly from their use.

Evolutionary theory explains the origin of complex organismal features through a combination of reusing and extending information from less-complex traits, and by needing to exploit only one of many unlikely pathways to a viable solution. While the appearance of a new trait may seem sudden, we show that the underlying information associated with each trait evolves gradually. We study this process using digital organisms, self-replicating computer programs that mutate and evolve novel traits, including complex logic operations.

Abstract:
Females and males have distinct trait optima, resulting in selection for sexual dimorphism. However, most traits have strong cross-sex genetic correlations, which constrain evolutionary divergence between the sexes and lead to protracted periods of maladaptation during the evolution of sexual dimorphism. While such constraints are thought to be costly in terms of individual and population fitness, it remains unclear how severe such costs are likely to be. Building upon classical models for the ‘cost of selection’ in changing environments ( sensu Haldane), we derived a theoretical expression fo

Abstract:
Cooperative social behaviours are ubiquitous in nature and essential to biological theory, yet they present an apparent paradox since cooperators benefit others while potentially incurring a fitness cost. The standard resolution is that cooperation is evolutionarily stable if cooperative behaviours are positively assorted, so their benefits are directed at other cooperators, shifting the problem to explaining the presence of positive assortment. If we view individuals as playing an evolutionary game, then the evolution of assorting traits changes the rules of the game to allow for greater coop

One of evolution's greatest innovations was group living; indeed, it is fundamental to our daily lives as humans. Yet despite intense theoretical and empirical work, the details of how group living arose and is maintained are poorly understood. A central question in this area concerns the strength of natural selection operating between groups of organisms (group selection) because some think this is key to the evolution of group behaviour. It is, however, challenging to measure natural selection occurring between groups and between the individuals within those groups simultaneously. Consequent

Interspecific diversity of reproductive traits among cactophilic Drosophila is described at different levels. The insemination reaction concept is reexamined using ultrastructural techniques. Examination of the vaginal contents of five Drosophila species suggested three distinct, more precise terms: the sperm sac, the mating plug and the true insemination reaction. Behavioral and physiological factors associated with the expulsion of the sperm sac in D. mettleri are explored in detail. Timing of the expulsion of the sperm sac appears to be correlated with the nutritional state of the female; t

<p> Adaptive phenotypic plasticity is a key mechanism by which organisms deal with variation in many different aspects of their environment. Adaptive plasticity can occur in any trait, from aspects of biochemistry and morphology to behaviors. Because so many different traits can be plastic, organisms often respond plastically to a given change in their environment, such as an increase in temperature, with adaptive changes in multiple traits. Nevertheless, how these different plastic responses interact with each other and evolve together has received little attention. My research addresses thes

Cooperation has shaped the evolution of life on Earth. The ants are the most numerically diverse of the eusocial Hymenoptera, and display wide variation in social complexity. This positions the ants as an ideal taxon in which to study social evolution in a comparative framework. Social evolution theory has generated many hypotheses that are testable in ants, however the lack of comprehensive or complete phylogenies, and the decentralised and scattered nature of trait data, has been an obstacle to these types of study.
