Wallace and Darwin, the Museum Mice from the Halls of the American Museum of Natural History, are off on another adventure It's amazing what you can find in a museum and how far you can travel in a small time machine made from a yoghurt cup Have you ever wondered where we humans all came from and how there came to be so many of us? The answers, as our two mice will show you, lie everywhere including in our own DNA. So there is the Big Picture of The Great Human Journey from the middle of Africa to Australia, America and Asia and then there's the Tiny (really tiny) Picture too of molecules and cells that we can trace inside ourselves and our Genome like long strings of letters that tell us where we came from and who our ancestors were, and where they were when and how they got there
