Evolution of Divergent Female Mating Preference in Response to Experimental Sexual Selection [PDF]
, 2014 Sexual selection is predicted to drive the coevolution of mating signals and preferences (mating traits) within populations, and could play a role in speciation if sexual isolation arises due to mating trait divergence between populations. However, few

Mating system variation drives rapid evolution of the female transcriptome in Drosophila pseudoobscura [PDF]
, 2014 This research was part funded by the Natural Environment Research Council, Grant Number: NE/I014632/1. The APC was paid through RCUK open access block grant funds.Interactions between the sexes are believed to be a potent source of selection on sex ...

Frontiers in Microbiology, 2020 Plasmids can provide advantageous traits to host bacteria, although they may impose a fitness cost. Chromosome-encoded factors are important for regulating the expression of genes on plasmids, and host chromosomes may differ in terms of their ...

Selection and the direction of phenotypic evolution
eLife, 2023 Predicting adaptive phenotypic evolution depends on invariable selection gradients and on the stability of the genetic covariances between the component traits of the multivariate phenotype.

Improved use of a public good selects for the evolution of undifferentiated multicellularity
eLife, 2013 We do not know how or why multicellularity evolved. We used the budding yeast, Saccharomyces cerevisiae, to ask whether nutrients that must be digested extracellularly select for the evolution of undifferentiated multicellularity.

Relaxed Substrate Specificity in Qβ Replicase through Long-Term In Vitro Evolution
Life, 2021 A change from RNA- to DNA-based genetic systems is hypothesized as a major transition in the evolution of early life forms. One of the possible requirements for this transition is a change in the substrate specificity of the replication enzyme.

Experimental evolution of a pheromone signal [PDF]
Ecology and Evolution, 2021 Abstract Sexual signals are important in speciation, but understanding their evolution is complex as these signals are often composed of multiple, genetically interdependent components. To understand how signals evolve, we thus need to consider selection responses in multiple components and account for the genetic

eLife, 2013 Selection favours single-celled mutants that stick together when a sugar needed for growth is in short supply, suggesting that multicellular life may have evolved as a by-product of selection for more efficient usage of resources.

Experimental Adaptation of Murine Norovirus to Calcium Hydroxide
Frontiers in Microbiology, 2022 Slaked lime (calcium hydroxide) is a commonly used disinfectant for fecal sludge. Although viruses are inactivated by lime treatment, whether RNA viruses adapt to lime treatment has not yet been determined.
