The Dollies were created in order to see if the cloning technique has been improved enough to cut the risk of problems—Dolly died at just six, after suffering health problems including advanced lung disease and arthritis. So far, Campbell says her clones appear healthy and are living “the life of Reilly—they potter around and get fed.”
