David Attenborough's Rise of Animals: Triumph of the Vertebrates

From the Seas to the Skies (1x1)

: 20, 2013

This episode details the origins of the vertebrates, which lie in the primitive fish that once swam in ancient seas. Remarkable advances allowed them to make the radical move onto land, and then take to the skies with the advent of flight. Brand new discoveries of fossils - ancient and living - combined with stunning CGI enable David to chart their unexpected journey out of the water to populate all corners of the globe.
