What does the world look like through insect eyes? What biological mechanisms make their vision different from our own? And how might those differences influence their evolution?

On this episode, we talk with UC Irvine evolutionary biologist Adriana Briscoe (@AdrianaBriscoe) about color vision in insects, particularly Heliconius butterflies. We discuss how their perception of the world has led to such massive diversification and how variation in the structure of the light-sensitive opsin proteins that detect light enable species to perceive the world differently. We also discuss how visual perception differences within species might shape behaviors such as pollination, and what ecological factors could drive visual system evolution across the tree of life.
