I would be not be surprised he is doing it just for money, making some false claims so he can get some research grants and make a living.
Of course if he can prove that any body can do the exact same thing with the same predictable results, and the results work 100% of the time, then perhaps I might reconsider.
Right now its highly most likely just a big HOAX by a scam artist or scam organization.
Ya there was some significant genetic tinkering in the distant past, it was all done during creation of all life by God and its still around!
