10 years ago(FILES) This file photo taken on February 3, 1997 in Edinburgh shows Dolly the cloned sheep born on July 5, 1996 at the Edinburgh Institute. Four genetically-identical copies of Dolly the famous cloned sheep, which suffered ill health and died prematurely in 2003, are going strong at the advanced age of nine, a study said on July 26, 2016. Debbie, Denise, Dianna and Daisy -- identical sisters of Dolly, though born 11 years later -- were "in pretty good health", according to researchers who studied whether cloned animals can live long, healthy lives. / AFP PHOTO / COLIN MCPHERSON
