In biology, a vestige is a trait or characteristic that evolved for a particular function, has subsequently become obsolete, and has typically begun to degenerate. Evolutionary biologist Timothy Jackson guides us down the rabbit hole of vestigiality to explore the evolution of obsolescence and makes the case that exploring these remnants of our past, and these basic evolutionary concepts, can help us better understand ourselves.
