不一致的信号通过保护低质量的雄性免受选择而改变了性选择的景观。像政治演说和产品广告一样，动物信号是高度重复的，其作用是说服接收者采取有利于信号者的行为。就像潜在的选民和消费者一样，接收者也会评估信号，为他们的行为决策提供信息。然而，性信号的不一致是普遍存在的，并可能给交配决策带来不确定性。在这里，我们表明，女性未能作出最佳的交配决定的基础上评估的信号质量，由于信号产生的不一致。自然水平的不一致性显着降低女性的偏好表达的非任意信号的男性质量。不一致性对偏好的重塑甚至比众所周知的环境噪音障碍更深刻。据我们所知，这是第一次证明不一致的信息如何降低动物的最佳决策，并对理解信号进化产生影响。
Inconsistent signaling alters the landscape of sexual selection by shielding low-quality males from selection. Like political stump speeches and product advertisements, animal signals are highly repetitive and function to persuade receivers to adopt behaviors benefiting the signaler. And like potential constituents and consumers, receivers assess signals to inform their behavioral decisions. However, inconsistency in sexual signals is widespread and potentially injects uncertainty into mating decisions. Here, we show that females fail to make optimal mating decisions based on assessments of signal quality due to inconsistency in signal production. Natural levels of inconsistency markedly reduced female preference expression for a nonarbitrary signal of male quality. Inconsistency reshaped preferences even more profoundly than the better-known impediment of ambient noise. To our knowledge, this is the first demonstration of how inconsistent messaging degrades optimal decision-making in animals, with implications for understanding signal evolution.
