S1 E2 • De l'eau à la Terre

Attenborough explores the Burgess Shale in Canada’s Rocky Mountains, where there is fossil evidence of an event 542 million years ago which saw animals increase in number, diversity and size as never before. These ancient rocks reveal the world’s first large predator, the first defences and the emergence of an animal group that would conquer the oceans: the hard-shelled arthropods.
