Begin your journey by shrinking down to enter a single redwood leaf, and discover that all life on Earth shares a common ancestry. Then travel through time to witness key events since the Big Bang—from the first stars to the formation of the solar system—that set the stage for life. Along the way, you will see two scenarios for the dawn of life on early Earth, and discover how our planet has changed since those microscopic beginnings. Narrated by Academy Award winner Jodie Foster.
