TO GO WITH AFP STORY BY MARIETTE LE ROUX (FILES) This file combination of pictures created on February 03, 1997 shows Dolly the cloned sheep born on February 1997 (R) and Polly the cloned sheep born on July 1997 at the Edinburgh Institute. When Dolly the cloned sheep was born 20 years ago on July 5, many hailed mankind's new-found mastery over DNA as a harbinger of medical miracles such as lab-grown transplant organs. Others trembled at the portent of a "Brave New World" of identical humans farmed for spare parts or as cannon fodder. As it turns out, neither came to pass. / AFP PHOTO / COLIN MCPHERSON
