S1, E1: The ability to genetically engineer human beings will change the human race forever.The secrets of DNA, the genetic code for life, are being unravelled. How are scientists learning to manipulate it to create new human beings – or parts of human beings? This film has access to the creation of the first cloned human embryo, and the people behind it. It gives us a glimpse of a future in which we will be able to bump into younger versions of ourselves in the street, replace every damaged organ with a new one that contains 99% of our own DNA, and nurture our offspring in artificial wombs.
