David Attenborough asks three key questions: how and why did Darwin come up with his theory of evolution? Why do we think he was right? And why is it more important now than ever before?
The Miller-Urey experiment was the first attempt to scientifically explore ideas about the origin of life. Stanley Miller simulated conditions thought be common on the ancient Earth. The purpose was to test the idea that the complex molecules of life (in this case, amino acids) could have arisen on our young planet through simple, natural chemical reactions.
In this episode Brian uncovers how the stunning diversity of shapes in the natural world are shadows of the rules that govern the universe. In Spain he shows how an attempt by hundreds of people to build the highest human tower reveals the force that shapes our planet. In Nepal, honey hunters seek out giant beehives that cling to cliff walls. The perfect hexagonal honeycombs made by the bees to store their honey conceal a mathematical rule. Off the coast of Canada, Brian explains how some of the most irregular, dangerous shapes in nature - massive icebergs that surge down from Greenland and into shipping lanes of the Atlantic - emerge from a powerful yet infinitely small force of nature. Even the most delicate six-sided snowflake tells a story of the forces of nature that forged it.
A journey through nature, commerce and adventure, The Fruit Hunters takes us from the dawn of humanity to the cutting of edge of modern agriculture — a series that will change not just the way we look at what we eat, but what it means to be human. The Fruit Hunters' first episode, "The Evolution of Desire," explores the origins of fruit's diversity and tells the story of humanity and fruit's intimate co-evolution. Every variety of fruit has a story, the story of the person who cultivated an individual plant, and then shared something wonderful with the world. To preserve this diversity is to retain this living memory. A passionate few, the fruit hunters, fight to preserve this diversity in a world increasingly dominated by economically driven monoculture.
