Ice and Stone

In the final episode of the series, Dr Alice Roberts goes in search of our elusive Stone Age ancestors. Along the way she visits the Channel island of Jersey where she meets a team of archaeologists hoping to shed new light on the much-maligned Neanderthals, and embarks on a kayak survey of the coastline looking for undiscovered sites hidden in the cliffs. At the Natural history museum Alice comes face to face with the dark side of our Ice Age ancestors lives - she sees evidence of cannibalism and the ritual use of human skulls. And she meets a team who are hoping to unlock the secrets of Stonehenge, not on Salisbury plain, but in the remote Preseli Hills of Wales.
