You've probably taken this into consideration, but
would Dr. West's research tend to refute this
hypothesis?
"Now, in a major new paper published in the April 28,
2000 issue of the journal Science (1), a group led by
Dr. Michael West has reported what may be the most
revolutionary advance in cloning research so far. They
have found that cloning can totally reverse cellular
aging."
