据预测，性选择将推动种群内交配信号和偏好（交配特征）的共同进化，如果由于种群间交配特征的差异而产生性隔离，则可能在物种形成中发挥作用。然而，很少有研究表明种群间交配特征的差异仅仅是由性选择造成的。实验进化是直接研究性选择对种群间交配性状差异作用的一种有前途的方法。我们操纵了伪眼果蝇种群的性选择机会（低与高）。先前对这些实验种群的研究表明，性选择操纵导致了几种求偶歌曲参数的性选择处理之间的差异，包括显著影响雄性交配成功率的脉冲间隔（IPI）。在此，我们使用回放设计来测量雌性对IPI的偏好，以测试130代实验性选择处理之间的偏好差异。研究结果表明，雌性偏好与雄性信号是共同进化的，在不同的性选择处理之间是相反的方向，这为性选择能够推动种群间交配特征的不同共同进化提供了直接证据。我们在性选择和物种形成的背景下讨论其含义。
Sexual selection is predicted to drive the coevolution of mating signals and preferences (mating traits) within populations, and could play a role in speciation if sexual isolation arises due to mating trait divergence between populations. However, few studies have demonstrated that differences in mating traits between populations result from sexual selection alone. Experimental evolution is a promising approach to directly examine the action of sexual selection on mating trait divergence among populations. We manipulated the opportunity for sexual selection (low vs. high) in populations of Drosophila pseudoobscura. Previous studies on these experimental populations have shown that sexual selection manipulation resulted in the divergence between sexual selection treatments of several courtship song parameters, including interpulse interval (IPI) which markedly influences male mating success. Here, we measure female preference for IPI using a playback design to test for preference divergence between the sexual selection treatments after 130 generations of experimental sexual selection. The results suggest that female preference has coevolved with male signal, in opposite directions between the sexual selection treatments, providing direct evidence of the ability of sexual selection to drive the divergent coevolution of mating traits between populations. We discuss the implications in the context sexual selection and speciation.
