I don't know if they have ever figured out why Dolly aged so fast, but I wouldn't be surprised that it has something to do with telomeres (the ends of chromosomes that shorten as one ages). Also, you'd get more harmful mutations as DNA ages. It's as if there is some biological clock that you can't reset by nuclear transfer (cloning).
