The molecular mechanism of speciation by sensory drive and its generality

本研究的目的是揭示由感觉驱动的物种形成的分子机制及其普遍性。在本研究中，我们发现在性选择的作用下，可能形成繁殖颜色的形态学基因已经进化。我们还发现了视觉基因的多样性，这些基因可能通过性选择形成了nothobranchus物种的繁殖颜色多样性。根据这些结果，我们证明了包括性选择在内的感觉驱动对繁殖颜色形成基因的整个物种形成机制，并通过对其他鱼类物种形成机制的分析证明了这一机制的普遍性。

The aim of this study was to reveal the molecular mechanism of speciation by sensory drive and its generality. In this study, we showed that the morphological genes those may be responsible for the formation of breeding coloration have evolved under sexual selection in cichlids. We also showed the diversity of visual genes that may form the diversity of breeding coloration by sexual selection in Nothobranchius species. According to these results, we demonstrated that the whole mechanism of speciation by sensory drive including sexual selection on the genes responsible for the formation of breeding coloration, and that the generality of this mechanism of speciation by analyzing other fish species.
