A Personal Voyage
One Voice in the Cosmic Fugue
Four billion years ago our planet was a molecular Garden of Eden. On the second leg of his 13-part journey through the Cosmos, Carl Sagan looks at how things might have turned out - how they in fact did, and why.
We also discover the only surviving descendant of the dinosaur, take a trip through a living cell, and speculate what life might be like on Jupiter.
