Since Darwin's conception of sexual selection theory, scientists have struggled to identify the
evolutionary forces underlying the pervasive differences between male and female …

A popular notion in sexual selection is that females are polyandrous and their offspring are
commonly sired by more than a single male. We now have large-scale evidence from …

The distinct reproductive roles of males and females, which for many years were
characterised in terms of competitive males and choosy females, have remained a central …

Quantitative literature reviews such as meta‐analysis are becoming common in evolutionary
biology but may be strongly affected by publication biases. Using fail‐safe numbers is a …

Over the last decades, the field of sexual selection underwent a paradigm shift from sexual-
stereotype thinking of “eager” males and “coy” females towards a more nuanced perspective …

Sexual conflict occurs when the genetic interests of males and females diverge. Recent
evidence supporting the view that male and female genomes are in conflict has now …

Sexual conflict is a conflict between the evolutionary interests of individuals of the two sexes.
The sexes can have different trait optima but this need not imply conflict if their optima can …

We review the current status of three well–established models (direct benefits, indirect
benefits and sensory drive) and one newcomer (antagonistic chase–away) of the evolution …

In unpredictably varying environments, strategies that have a reduced variance in fitness
can invade a population consisting of individuals that on average do better. Such strategies …

The immunocompetence handicap hypothesis was formulated 12 years ago in an attempt to
offer a proximate mechanism by which female choice of males could be explained by …
