进化生物学中的一个中心范式是，两性在健身兴趣上的根本分歧（“性冲突”）可以导致性别特异性特征的进化，从而降低异性个体的健身度，以及两性之间的性对抗共同进化。然而，以这种方式进化的特征的明确例子--一种性别的单一特征明显地抑制了异性成员的适应性，导致了对抗性的共同进化--是罕见的。果蝇的精液蛋白“性肽”（SP）可能是最广泛引用的一个例子，它似乎对雌性有害，而对雄性有益。在交配过程中由男性射精转移，SP触发女性行为和生理的深刻和广泛的变化。早期的研究报告说，SP的转移增强了男性的健康，同时抑制了女性的健康，这为SP已经进化到为了男性的利益而操纵女性的广泛观点提供了基础。在这里，我们认为，这种观点是（一）一个更广泛的矛盾的实证研究机构的简化，（二）窄相对于理论描述的起源和维护性选择的特征，和（iii）很难调和与我们所知道的进化史SP的影响女性。我们开始绘制的思想史SP，在近（其生产，功能和作用机制）和最终（其健身后果和进化史）的水平，回顾如何SP的研究是中央的发展领域的性冲突。我们描述了一个普遍的范式SP的演变：SP起源并继续演变为男性利益操纵女性。与这种观点相反，我们认为有三个理由，证据的权重不支持接受SP会降低女性健康的观点：（i）SP对女性健康影响的研究结果好坏参半，通常是中性或积极的，只有在营养极端的情况下才会出现健康成本;（ii）SP的成本在野生种群中是否可观仍然未经检验;和（iii）最近描述的混淆，在遗传操作的SP提出的可能性，措施的成本和收益的SP已被扭曲。除了SP的健身效果，比较和遗传数据也很难与女性遭受SP健身成本的想法相一致。相反，这些数据-从功能和进化遗传学以及女性对SP反应的神经回路-表明进化历史涉及女性生殖道中专用SP传感器的进化，这可能是因为它有利于女性，而不是伤害他们。最后，我们探索的理论和证据表明，SP有利于女性作为男性质量或精子接收和存储（或两者兼而有之）的信号。我们概述的SP进化的扩展观点认识到合作和拮抗选择在生殖性状的起源和维持中所起的依赖于环境和波动的作用。
A central paradigm in evolutionary biology is that the fundamental divergence in the fitness interests of the sexes (‘sexual conflict’) can lead to both the evolution of sex‐specific traits that reduce fitness for individuals of the opposite sex, and sexually antagonistic coevolution between the sexes. However, clear examples of traits that evolved in this way – where a single trait in one sex demonstrably depresses the fitness of members of the opposite sex, resulting in antagonistic coevolution – are rare. The Drosophila seminal protein ‘sex peptide’ (SP) is perhaps the most widely cited example of a trait that appears to harm females while benefitting males. Transferred in the ejaculate by males during mating, SP triggers profound and wide‐ranging changes in female behaviour and physiology. Early studies reported that the transfer of SP enhances male fitness while depressing female fitness, providing the foundations for the widespread view that SP has evolved to manipulate females for male benefit. Here, we argue that this view is (i) a simplification of a wider body of contradictory empirical research, (ii) narrow with respect to theory describing the origin and maintenance of sexually selected traits, and (iii) hard to reconcile with what we know of the evolutionary history of SP's effects on females. We begin by charting the history of thought regarding SP, both at proximate (its production, function, and mechanism of action) and ultimate (its fitness consequences and evolutionary history) levels, reviewing how studies of SP were central to the development of the field of sexual conflict. We describe a prevailing paradigm for SP's evolution: that SP originated and continues to evolve to manipulate females for male benefit. In contrast to this view, we argue on three grounds that the weight of evidence does not support the view that receipt of SP decreases female fitness: (i) results from studies of SP's impact on female fitness are mixed and more often neutral or positive, with fitness costs emerging only under nutritional extremes; (ii) whether costs from SP are appreciable in wild‐living populations remains untested; and (iii) recently described confounds in genetic manipulations of SP raise the possibility that measures of the costs and benefits of SP have been distorted. Beyond SP's fitness effects, comparative and genetic data are also difficult to square with the idea that females suffer fitness costs from SP. Instead, these data – from functional and evolutionary genetics and the neural circuitry of female responses to SP – suggest an evolutionary history involving the evolution of a dedicated SP‐sensing apparatus in the female reproductive tract that is likely to have evolved because it benefits females, rather than harms them. We end by exploring theory and evidence that SP benefits females by functioning as a signal of male quality or of sperm receipt and storage (or both). The expanded view of the evolution of SP that we outline recognises the context‐dependent and fluctuating roles played by both cooperative and antagonistic selection in the origin and maintenance of reproductive traits.
