The Origins of Life

Dr. Robert Hazen of the Carnegie Institution for Science ( hazen.gl.ciw.edu/ ) will discuss evidence about the origins of life almost 4 billion years ago. Dr. Hazen is author of Genesis: The Scientific Quest for Life's Origins; as well as The Story of Earth: The First 4.5 Billion Years, from Stardust to Living Planet, and many other books and articles. How did the hydrogen that formed soon after the Big Bang 13.82 billion years ago, the carbon and oxygen forged in stars at least 5 billion years ago, and other elements and molecules combine to form the first life on earth?
