David Attenborough embarks on an epic 500 million year journey to unravel the incredible rise of the vertebrates – producing the largest, the fastest and the most intelligent creatures the world has ever seen. This journey takes him on his first filming trip in China – a region he’s long dreamt of exploring - to investigate a series of remarkable ancient creatures that are being hailed as key missing links to our evolutionary past. The evolution of animals with backbones is one of the greatest stories in natural history. Brand new discoveries of fossils – ancient and living – combined with stunning CGI and cinematography enable David to tell this fascinating story and reveal that humans are the heirs to a magnificent evolutionary heritage. From the team that produced David Attenborough’s triple Emmy award-winning series, ‘First Life’.
