The mismeasurement of sexual selection
Sexual selection can explain major micro- and macro-evolutionary patterns. Much of current theory predicts that the strength of sexual selection (i) is driven by the relative abundance of males and females prepared to mate (i.e. the operational sex ratio, OSR) and (ii) can be generally estimated by calculating intra-sexual variation in mating success (e.g. the opportunity for sexual selection, Is). Here, we demonstrate the problematic nature of these predictions. The OSR and Is only accurately...[Show more]
