Disentangling the complex interactions between females and the sperm of multiple males

A new study published in Evolution Letters dissects the complex processes and interactions between the sexes that determine which male fathers the offspring when females have mated with different males. Here, lead author Stefan Lüpold explains the motivation for, and key conclusions of, the study. Students of evolutionary biology will at some point encounter sexual selection, a …

Searching for sexually antagonistic genes: the story behind the paper

A new Comment & Opinion piece published in Evolution Letters provides a roadmap for analysing genetic data in the context of sex-specific adaptation. Here, lead author Filip Ruzicka explains the motivation for and key conclusions of the study. Sexual dimorphism—or differences in female and male traits—represents the most striking instance of adaptive differentiation within single …
