150,000 years ago humans are just one of many species on the planet. But we are creative. In our hands a simple stone becomes a tool. A sharp flint becomes a Spear. It allows us to overcome our physical limitations. 12,000 years ago an Ice Age gripped the world. Our ancient ancestors come up with a miniature variation on the spear – an invention we still use today: the needle. Enabling us to make appropriate clothing, the needle allows humans to be more versatile, more adaptable, better able to survive.
