For decades, radio astronomers have combed the skies for signals from alien life. But according to our guest, Dr. Peter Godfrey-Smith, we’ve overlooked a form of intelligence so remote from ours it might as well be alien. It’s our evolutionary cousin, the octopus, a sea-dwelling mollusk that made headlines in 2016 for escaping from a New Zealand aquarium through a drain pipe. Because our most recent common ancestor was so simple and ancient, says Godfrey-Smith, the octopus represents an independent experiment in the evolution of minds and complex behavior. It confronts us with a mind in many ways radically different from our own, with which humans have nonetheless managed to make contact. Diving with cephalopods has led him to wonder: what might these strange creatures have to teach us about consciousness?
