摘要: One of the most enigmatic observations in evolutionary biology is evolution morphological or physiological traits one sex that physically injure members other [1-3]. Such occur a wide range taxa [3] and from toxic ejaculate substances [4-6] to genital external spines wound females during copulation [7-11]. Current hypotheses for adaptive such injurious rest entirely on assumption they are beneficial their bearer by aiding reproductive competition [1, 3]. Here, we assess this key seed beetles where males females. We demonstrate male spine length positively correlated with harm mating but also longer more successful sperm competition. This first complete support proposal sexual selection can favor inflict injury upon However, our results suggest pleiotropic by-product, elevate success means than causing harm.
