Beetle daisies evolved floral spots that mimic female bee flies to entice mate-seeking males for pollination. A new study shows that these deceptive spots emerged through stepwise co-option of multiple genetic elements, shedding light on the origin of complex phenotypic novelties.
甲虫雏菊进化出了模仿雌性蜜蜂蝇的花朵斑点,以吸引寻求交配的雄性进行授粉。一项新的研究表明,这些欺骗性斑点是通过逐步共选择多个遗传元件而出现的,这为复杂表型新颖性的起源提供了线索。
