David Attenborough explores the rise of life on the planet, from the explosion of first life on seabeds hundreds of millions of years ago to life today.
When Sir David Attenborough was in his mid-eighties, many thought he had retired; instead, he was embarking on a seven-year journey, revisiting some of the most astonishing landscapes and creatures on the planet.
From the idyllic shores of the Galapagos to the underwater worlds of the Great Barrier Reef, David Attenborough seeks to understand how the natural world has thrived in what might otherwise seem like impossible environments.
