Tim Flannery, Australian scientist and author, offers a sweeping account of the dual evolutionary history of Earth and the life it supports. Beginning with the birth of stars to the creation of water and the accident of simple life forms, Flannery documented life up through the 2-million-year rise of our human species and pondered our future as a "superorganism" capable of either sustaining or destroying the planet’s ecosystems.

Presented by the Harvard Museum of Natural History.
