Sheep "can live to 11 or 12" say the scientists. But how old was Dolly?
Dolly was born in July 1996 after being cloned from the udder cell of a six-year-old adult ewe, and named after the singer Dolly Parton.Some have said that this means that Dolly was really twelve years old. Whatever her age, she certainly warrants her coming display in the National Museum.
