Dolly the Sheep changed history when she was the first animal cloned from an adult cell. Before the famous Dolly (named after Dolly Parton), other animals had been cloned, but they were cloned from the DNA of embryo cells. This was a huge leap for the world of science! This cloned animal had babies, but the cloning shortened her lifespan and gave her some arthritis and lung problems. Dolly has led the way for many other animal clones — who knew a sheep could change science as we know it?
