Ella Al-Shamahi, a rising star in Neanderthal research, enlists the skills of Andy Serkis, the master of performance capture, and a group of experts to create, for the first time ever, a scientifically accurate 3D Neanderthal. They discover that Neanderthals were more like us than we ever thought.

For around 400,000 years Neanderthals live and thrived right across Europe and Western Europe. But about 40,000 years ago they disappeared. In this second episode in the series, Ella Al-Shamahi - with the help of Hollywood actor Andy Serkis - explores the fate of the Neanderthals, asking why they became extinct, and discovering how they live on inside of us today.
