BBC - How to Grow a Planet. Part 2: The Power of Flowers (2012)

Stars: Iain Stewart

Geologist Ian Stewart explain in three stages of natural history the crucial interaction of our very planet's physiology and its unique wildlife. Biological evolution is largely driven bu adaptation to conditions such as climate, soil and irrigation, but biotopes were also shaped by wildlife changing earth's surface and climate significantly, even disregarding human activity.

Episode 2: In the second episode, Iain discovers how flowers have transformed our planet. He journeys to the remote islands of the South Pacific to track down the earliest flowers. In the deserts of Africa and rainforests of Vietnam, he sees how they brought brilliant colour to the most barren landscapes and sculpted the earth itself. And he learns how they drove the evolution of all animals - kick-starting our human story.
