Wild fun: How animals play

YouTube is filled with adorable videos of animals at play, and studying that play is helping uncover mysteries of evolutionary behavior. University of Massachusetts, Amherst professor David Toomey joins host Krys Boyd to discuss why piglets flop, dogs slide and octopuses play, and what that tells us about animal cognition and biology. Plus, we’ll dive deeper into the world of cephalopods. Toomey’s book is “Kingdom of Play: What Ball-bouncing Octopuses, Belly-flopping Monkeys, and Mud-sliding Elephants Reveal about Life Itself.”
