Professor Iain Stewart uncovers clues hidden within the New York skyline, the anatomy of American alligators and inside Bolivian silver mines, to reconstruct how North and South America were created. We call these two continents the New World, and in a geological sense they are indeed new worlds, torn from the heart of an ancient supercontinent - the Old World of Pangaea.

Two hundred million years ago the continent we know as Eurasia didn't exist. Prof Iain Stewart shows that where the South of Eurasia is today there was once a ninety-million-square-kilometre Ocean known as the Tethys. It is the destruction of the Tethys Ocean that holds the key to Eurasia's formation. However, the formation of Eurasia is just the beginning of the story.
