This week, Anna introduces Amber to the site of Boxgrove, in what is now Sussex, England. It's one of the oldest known hominin sites in the UK, and features the remains of our early relative, Homo heidelbergensis. Join us to learn more about the Muddle in the Middle, the world's hardest jigsaw puzzle, and the molecular clock.
