We test the assumption that humans are the smartest species by pitting a range of animals against people. Our contestants — both human and nonhuman — are put through a series of tests, including cracking a safe, identifying priceless art, recognizing criminals and other incredible feats, to discover who has the best memory, spatial awareness, problem solving skills and navigational prowess. Can a taxi or a rat make it through a maze quicker? Who’s better at strategy — students or a cockatoo? And who’s the better treasure hunter — a man or a fish? The results are surprising, hilarious and often extraordinary.
