Takes us on a fascinating odyssey, in the company of some world-reknowned scientists whose discoveries into the natural world are providing some clues to the question of where do we come from. Could the first life forms, which appeared some four billion years ago, have originated in organic cosmic dust? One thing is certain: all life on our planet shares some of the same genetic code and developed from the same evolutionary tree. But could life have evolved in a completely different way? What if there were living organisms with a genetic structure entirely unlike ours? The key to this mystery may be found in space.
