Brian and Robin consider the quirks that make human beings unique while Bill Bailey learns how to speak like a chimp and Conan O’Brien explains how his brain is wired for comedy.

Brian Cox and Robin Ince consider the quirks that make human beings unique and check in with experts from The Infinite Monkey Cage back catalogue. Prof Alice Roberts explains that our ancestors interbred with Neanderthals to make us who we are today. We’re also excellent at communicating with other species, as comedian Bill Bailey learns when he gets a lesson in chimp speak from the legendary primatologist Dr Jane Goodall. Then there are the bits of us that are pretty different, like our large brains and Conan O’Brien says his has been wired for comedy. Everyone agrees natural selection hasn’t always equipped us with the best tools for the job and David Baddiel argues the eye is a perfect example of a human design flaw.
