(FILES) This file photo taken on February 03, 1997 shows Dolly the cloned sheep looking out from her enclosure at the Edinburgh Institute. When Dolly the sheep was put down before her seventh birthday in 2003, she was said to suffer from age-related osteoarthritis, raising red flags that clones may grow old faster. But scientists said on November 23, 2017 that the fear of premature, clone-related ageing appears to have been misplaced. Dolly's joint disease was, in fact, quite normal.Researchers in Scotland and England based their conclusion on X-rays of Dolly's skeleton, held by National Museums Scotland (NMS), in Edinburgh. / AFP PHOTO / COLIN MCPHERSON
