For centuries, the idea of intelligent animals struck most people as ridiculous. But not any more - the latest science reveals that animals are a lot smarter than we thought.

From skateboarding dogs to chimp maths geniuses, Liz Bonnin embarks on a worldwide search for the planet's most intelligent animals, devising some ingenious IQ puzzles and even putting herself to the test to find out.

Liz gets creative with dolphins, shares a eureka moment with orangutans and defends the reputation of the human race when she goes head-to-head with a chimp genius in a test of maths and memory. There is an octopus escapologist, John Humphrys puts a goldfish through its paces on Mastermind, and Tillman the skateboarding dog wows crowds in Los Angeles.

Prepare to be amazed, entertained and even outwitted by the world's Super Smart Animals. Show less
