Joe Hanson on Animals, Sound, and Semiotics

When an animal makes a sound, does that sound have meaning?  Mike talks to Dr. Joe Hanson, a biology expert and curator/host of It’s Okay To Be Smart, about how male Pacific humpback whales woo female Pacific humpback whales, and you’ll get a glimpse into the world of animals, sound, and semiotics.  You might even hear them make whale noises … Mike and Joe, that is, not the actual whales.  Plus special cameos by “Wonderwall” and “The Fox.”
