CODE FOR LIFE:

CODE FOR LIFE:

Beginning more than three and a half billion years ago, a tiny, primitive molecule encoded instructions deep within itself. Then it passed these instructions on to its children, who passed it to their children and so on - all the way down through time to all living things today.

The human genome, written in a code of just four letters, tells us who we really are - and that generates many questions!

Is this process of natural selection coming to an end? Should we choose the best that is in us for our children? If so, who gets to decide what is meant by "the best that is in us"? From amino acids in space to human genes in corn -- this is the story.
