各种丽鱼科鱼所呈现的令人惊叹的色彩不仅让水族馆饲养员着迷,而且由于最近揭示了其在非洲湖泊适应性辐射中的作用,也受到了对物种形成感兴趣的生物学家的极大关注。我们回顾了颜色在维多利亚湖慈鲷的物种形成和适应性进化中的重要作用,这些慈鲷在很短的进化期内经历了适应性辐射。成熟的雄性慈鲷在选择配偶时会展示自己的颜色。她们的皮肤颜色反射光,反射光形成颜色信号,被女性的视觉系统接收。视觉感知的适应性发散会塑造和发散色彩,以匹配适应的视觉感知。视觉感知和颜色的分歧表明颜色信号的分歧导致物种之间的生殖隔离,这个过程导致物种形成。共存物种之间颜色信号的差异通过防止杂交来维持生殖隔离。因此,颜色的多样性导致了物种形成,并维持了维多利亚湖慈鲷的物种多样性。
The amazing coloration shown by diverse cichlid fish not only fascinates aquarium keepers, but also receives great attention from biologists interested in speciation because of its recently-revealed role in their adaptive radiation in an African lake. We review the important role of coloration in the speciation and adaptive evolution of Lake Victoria cichlids, which have experienced adaptive radiation during a very short evolutionary period. Mature male cichlids display their colors during mate choice. The color of their skin reflects light, and the reflected light forms a color signal that is received by the visual system of females. The adaptive divergence of visual perceptions shapes and diverges colorations, to match the adapted visual perceptions. The divergence of visual perception and coloration indicates that the divergence of color signals causes reproductive isolation between species, and this process leads to speciation. Differences in color signals among coexisting species act to maintain reproductive isolation by preventing hybridization. Thus, the diversity of coloration has caused speciation and has maintained species diversity in Lake Victoria cichlids.
