Butterfly colour vision genetic switch identified by UC San Diego biologists
Original: UC San Diego biologists identified the genetic switch that gave butterflies an extra light-detecting cell in their eyes, expanding their colour vision beyond imagination
Biologists at the University of California, San Diego have identified the genetic switch that gave butterflies an extra light-detecting cell in their eyes. The finding explains how butterflies perceive a far wider range of colours than humans, shedding light on the evolution of insect vision. Researchers say the discovery could inform broader studies of how visual systems evolve across species.
Why now: The discovery reveals the evolutionary origin of butterflies' extraordinary colour vision, a striking biology finding.
