Why do some rove beetles look like ants? Why do living things evolve similar solutions to common problems? Is there predictability within the evolutionary process? On this episode, Art and Marty talk with Joe Parker, an entomologist at Caltech. Joe has been collecting beetles since the age of 16, when he first became amazed by their incredible diversity. He now focuses on rove beetles and studies their evolutionary relationship with ants to understand how different species converge upon similar traits.
