It’s the ultimate detective story. How did life begin on Earth, and could such a process exist elsewhere in the Universe? Many scientists think that planets with life may be as common as stars. Before we can search for life elsewhere, we must solve the mystery of life on Earth. This presentation traces “life” from an early hostile Earth to the diverse and amazing array of living things we know today.
