Modeling of R.A. Fisher's ideas about the evolution of male ornamentation using quantitative genetics began in the 1980s. Following an initial period of enthusiasm, interest in these models began to wane when theoretical studies seemed to show that the rapid evolution of ornaments would not occur if there were costs associated with female mate choice. Recent theoretical work has shown, however, that runaway evolution and other kinds of extensive diversification of ornaments and preferences can occur, even when female choice is costly. These new models highlight crucial parameters that profoundly influence evolutionary trajectories, but these parameters have been neglected in empirical studies. Here, we review quantitative genetic models of sexual selection with the aim of fostering communication and synergism between theoretical and empirical enterprises. We also point out several areas in which additional empirical work could distinguish between alternative models of evolution.
利用数量遗传学对R.A.费希尔关于雄性装饰物进化的观点进行建模始于20世纪80年代。在经历了最初的一段热情期后，当理论研究似乎表明如果雌性配偶选择存在成本，装饰物的快速进化就不会发生时，对这些模型的兴趣开始减弱。然而，最近的理论研究表明，即使雌性选择存在成本，失控进化以及装饰物和偏好的其他种类的广泛多样化也可能发生。这些新模型突出了深刻影响进化轨迹的关键参数，但这些参数在实证研究中一直被忽视。在这里，我们回顾性选择的数量遗传模型，旨在促进理论和实证研究之间的交流与协同。我们还指出了几个额外的实证工作可以区分不同进化模型的领域。
