We asked Jim Watson to give us a tour of the future. He belives DNA science should be used to change the human race. His views are both extraordinary and extremely controversial. Watson argues for a new kind of eugenics -- where parents are allowed to choose the DNA of their children -- to make them healthier, more intelligent, even better looking. His vision may be disagreeable, yet it's a natural consequence of the decades of scientific exploration launched by his and Francis Crick's discovery of the double helix. It's worth considering what effect the advancements in genetic science may have on our future
