Exclusive male care of offspring is the rarest form of postzygotic parental care among animals and has arisen independently in only 13 arthropod taxa. To distinguish the effects of sexual selection from those of natural selection on the evolution of arthropod paternal care, predictions concerning several life-history and behavioral traits resulting from both forms of selection are made and tested across all known taxa with exclusive paternal care. Comparisons suggest parallels between prezygotic nuptial gifts and exclusive postzygotic male care and support the hypothesis that, in arthropods, male behaviors that enhance female reproductive success either directly, by releasing females from the fecundity constraints of maternal care (enhanced fecundity hypothesis), or indirectly, by identifying mates with superior genes (handicap principle), are traits on which sexual selection has acted. Under such conditions, males that are willing to guard young become preferred mates for gravid females and enjoy greater promiscuity than males that are unable or unwilling to guard. Females use nest construction or the act of guarding another female's eggs as honest signals of paternal intent and quality.
在动物中，雄性独自照顾后代是合子后亲代抚育最罕见的形式，仅在13个节肢动物类群中独立出现过。为了区分性选择和自然选择对节肢动物父性抚育进化的影响，我们针对这两种选择形式所产生的若干生活史和行为特征进行了预测，并在所有已知的雄性独自照顾后代的类群中进行了检验。比较结果表明，合子前的婚飞礼物与合子后雄性独自照顾后代之间存在相似之处，并支持了以下假设：在节肢动物中，那些通过直接解除母体抚育对繁殖力的限制（增强繁殖力假说）或间接识别具有优良基因的配偶（ handicap原则）来提高雌性繁殖成功率的雄性行为，是性选择作用的特征。在这种情况下，愿意守护幼崽的雄性成为怀孕雌性更青睐的配偶，并且比那些无法或不愿意守护的雄性享有更高的滥交率。雌性将巢穴建造或守护其他雌性卵的行为用作父性意图和质量的真实信号。
