Step back in time on a journey to the key Neanderthal sites of southern France between Bordeaux and Nice with Palaeolithic archaeologist and author Rebecca Wragg Sykes. See the oldest traces left by humankind: stone tools, art objects, cave paintings and other remains that have changed the way we think about Neanderthals. For the first 40 years after their fossils were recognised, nobody knew whether or not Neanderthals had any culture or complex cognitive abilities. In this tour, Rebecca shows how advances in archaeological methods over the last three decades have revealed a very clear picture.
