| Summary |
While the discovery of DNA appeared to supplant much, or possibly all, of the nature vs. nurture question, this documentary highlights how life choices , stress, nutrition, may in fact impact or even change DNA processes. The filmmakers explore newer evidence that suggests DNA replication may not be as automatic as had been thought, and is shaped and affected by a second "epigenetic" chemical code that reacts with environmental changes, activating or deactivating various genes, all with potentially dramatic and even permanent results. As such, the nature vs. nurture question gains new prominence and new import, with the implication that people's choices with their own lives and the lives of their children have far-reaching consequences. |
