None can support complex life except earth. But the conditions on earth were not always so suitable for life, and scientists are working to reconstruct the history of two essential requirements whke tlanet hatable. The first is free oxygen in the atmosphere. The other is a moderate and stable climate. Paleontologist andy knoll has spent much of his career examining earths rock record to piece together the history of early life and the rise of oxygen. Theres this close waltz, if you will, between the history of earths physical environments and the history of life. Narrator geologist paul hoffman studies the time in our planets history when the climate was much more extreme, a period called the snowball earth.
