Predation, a major cause of natural selection, is classically thought to target the weak and sick. However, predators can animals with condition-dependent sexual traits, therefore, high-quality individuals also be focus predation. Thus, it not always clear which are foci or how this affects trait evolution. Here, we tested for evolutionary effects sex-specific predation on male female longevity using replicate populations broad-horned flour beetle Gnatocerus cornutus . We found that male-limited resulted in evolution reduced increased longevity, while female-limited had no either sex. document costs reproduction. Coupled other findings, our results suggest impacts males and, because negative intersexual genetic correlations, increases longevity.
