Sexual selection

The causes, consequences, and genetic basis of the maladaptation that arises when males and females share a genome.

We use theoretical models to examine the evolution of female choice when there is both intralocus sexual conflict and local adaptation. We show that IASC can weaken female preferences for high-condition males – or even cause a preference for males in low condition – depending on the relative benefits of producing well-adapted sons versus daughters. We discuss the relevance of our results to conservation genetics and empirical evolutionary biology.

The capacity of a population to adapt to selection (evolvability) depends on whether the structure of genetic variation permits the …

Using experimental evolution, we test whether allowing or preventing sexual selection on males affects the rate at which flour beetle populations evolve resistance (and susceptibility) to insecticide.

Raia et al. propose that the evolution of the shape and complexity of animal ornaments (e.g., deer antlers) can be explained by …

Polyandry has been hypothesized to allow females to “bet hedge” against mating only with unsuitable mates, reducing variance in …

Garcia-Gonzalez et al. [1] conducted an original and elegant experiment examining whether fertilization of a female’s eggs by …

A major unsolved question in evolutionary biology concerns the relationship between natural and sexual selection. Sexual selection …

Studies of sexual communication typically focus on the design and information content of a signal of interest, but the timing of signal …

As recently outlined in TREE [1], many animals and plants are thought to load their male gametes with multiple types of RNA, some of …
