The Great Lakes region provided geologists with much of the evidence for the frequent ice ages that visited North America. But the lakes may be a rather transient feature of the continent dependent upon the recurring ice ages to maintain their existence.

Life's Rocky Start

Four and a half billion years ago, the young Earth was a hellish place—a seething chaos of meteorite impacts, volcanoes belching noxious gases, and lightning flashing through a thin, torrid atmosphere. Then, in a process that has puzzled scientists for decades, life emerged. But how? NOVA joins mineralogist Robert Hazen as he journeys around the globe. From an ancient Moroccan market to the Australian Outback, he advances a startling and counterintuitive idea—that the rocks beneath our feet were not only essential to jump-starting life, but that microbial life helped give birth to hundreds of minerals we know and depend on today. It's a theory of the co-evolution of Earth and life that is reshaping the grand-narrative of our planet’s story.

Part 2

(PART 2) A team of experts and explorers venture into the Danakil desert in Northern Ethiopia to investigate the incredible geology of the area, and to find out how the people and their animals survive in the hottest place on earth. Kate Humble investigates how tough life is for an Afar woman; Steve Leonard wants to learn about the relationship between the Afar and their animals, and to help with animal medicine where he can; Dr Mukul Agarwal looks at the health issues faced in this most hostile of environments; earth scientist Dougal Jerram looks at the extraordinary volcanic activity of the region and the part it plays in the bigger geological picture of the Rift Valley; and biologist Richard Wiese searches for extreme life forms in the boiling soil of a massive volcanic fissure.
