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.

Some animals have an extraordinary ability to find their way. The dung beetle, an insect revered by ancient Egyptians, uses the sun, the moon and even the Milky Way to move its prized ball of dung in the right direction. Pigeons are often considered feeble birdbrains, but they have incredible memories that can recall several complex travel routes with amazing accuracy and they even use man-made roads and hedgerows to find the quickest way home.
