David Attenborough reviews the scientific discoveries that have transformed our view of life on earth during his lifetime. How and where did life first begin? How do continents move? How do animals communicate? And why do they behave the way they do? Sir Attenborough shares his memories of the scientists and the breakthroughs that helped shape his own career. He also recalls some of his most memorable attempts to bring new science to a television audience - by standing in the shadow of an erupting volcano as lumps of hot lava crashed around him, by being charged by a group of armed New Guinean tribesmen and the extraordinary sight of chimps hunting monkeys, captured on camera for the first time by Attenborough and his team.
In this final episode Professor Brian Cox travels to Iceland, where the delicate splendour of a moonbow reveals the colours that paint our world, and he visits a volcano to explain why the sun shines.

Finally, at an observatory high in the Swiss Alps, he shows how these colours aren't simply beautiful, but that understanding how they're created is allowing us to search for other Earths far out in the cosmos.
