Le lien cosmique -- Film Description:
"Where do we come from? The award-winning The Cosmic Link takes us on a fascinating odyssey, in the company of some world-renowned scientists whose discoveries into the natural world are providing some clues to this age-old question. 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. Christian de Duve, biochemist and Nobel Prize winner, astronomer Michel Mayor and biopaleontologist Michael Caldwell of the Canadian Museum of Nature help shed brilliant light on our cosmic link with the rest of the universe."
