Origins of Life

Four billion years ago, the infant Earth was a seething cauldron of erupting volcanoes, raining meteors, and hot noxious gases, totally devoid of life. But a relatively short time later-100 million to 200 million years-the planet was teeming with primitive organisms. What happened? Professor Robert M. Hazen, one of the nation's foremost science educators and a leader of a NASA-supported team that is studying the origins of life in the universe, leads you on a 24-lecture expedition to find the answer to this momentous question.
