Scientists find genetic switch that expanded butterflies’ colour vision

Researchers have identified a specific genetic switch responsible for the expansion of color vision in butterflies. This discovery explains the biological mechanism that allows these insects to perceive a broader spectrum of light, which is essential for their survival and environmental interactions.

By isolating the genetic trigger, scientists have gained new insights into the evolutionary processes that drive sensory adaptation in the animal kingdom. This finding highlights the complexity of insect vision and provides a foundational understanding of how genetic mutations can lead to significant physiological changes in species over time.
