Deskripsi
Natural and sexual selection can be in opposition favouring different trait sizes, but disentangling these processes empirically is difficult. Here Okada et al. show that predation on males shifts the balance of selection in experimentally evolving beetle populations, disfavoring a sexually-selected male trait but increasing female fitness.
