在各种哺乳动物中，通过替换雄性来系统地杀死依赖后代是迄今为止发现的性利益冲突的最戏剧性后果之一（Hrdy，1974; Fossey，1984; Packer和Pusey，1984）。遭受这种损失的雌性动物通常在较短的时间间隔内进入发情期，如果它们的婴儿被允许成熟的话。因此，替代的雄性通过杀死前一个雄性所生的婴儿来增加他所生后代的数量。Hrdy（1979）和谢尔曼（1981）对哺乳动物的杀婴行为进行了综述，Hausfater和Hrdy（1984）编辑了一本关于杀婴的书，其中包括许多评价性选择是杀婴原因的论文，杀婴并不是取代雄性的唯一反应。在某些鸟类和鱼类中，替换个体不仅可能不会表现出杀精作用，而且可能完全采用可能无关但依赖的后代。在其他物种中，替代个体对新配偶的依赖性后代表现得漠不关心，但却没有表现出杀父的行为。在这一章中，我扩大了我们的视角。
The systematic killing of dependent offspring by replacing males in various mammals represents one of the most dramatic consequences of sexual conflict of interest yet discovered (Hrdy, 1974; Fossey, 1984; Packer and Pusey, 1984). Females suffering such losses often come into estrous in a shorter time interval then would occur if their infants had been allowed to mature. Consequently, the replacement male increases the number of offspring he sires by killing infants fathered by the previous male. Hrdy (1979) and Sherman (1981) provide reviews of such infanticide in mammals and Hausfater and Hrdy (1984) have edited an entire book on infanticide that includes many papers evaluating sexual selection as a cause of infanticide.Infanticide is not the only response of replacing males. In some birds and fishes, replacing individuals not only may fail to exhibit infanticide but also may fully adopt presumably unrelated but dependent offspring. In other species, replacing individuals behave indifferently toward the dependent offspring of their new consort, but, nonetheless, fail to exhibit infanticide. In this chapter I enlarge our perspectives
