That analysis spanned only a couple of generations.
Quote:identification of Richard III
In that case (1) the old DNA was taken from an individual that was suspected of being a
specific known famous individual, (2) the modern DNA was taken from people who were
known to be descendants of that famous individual or his close relatives, (3) several of those "known descendants" were in fact not such thing, and (4) the DNA match was only
one contributing factor to the conclusion.
As for (4), by itself the match shows only that the female ancestral lines of the skeleton and of the two matching modern subjects converged at some point. That is, there was some woman X that was the great^N-grandmother of the skeleton and also the great^M-grandmother of those two people, both through females only; and that N was not "too" large (otherwise there would have been some mutations in one or both DNA samples). It does not prove that the two individuals were descendants of
close relatives of the skeleton (that is, that N was small).
There were only two competing hypotheses, "the skeleton is Richard III" or "the skeleton is someone else". The DNA match, alone, would have made the first hypothesis more likely, but not proved it. What made it 99%+ certain was all the other evidence: the anatomical and medical conditions of the skeleton, the historical records of his death and burial, the C14 date, etc. Before the DNA test, it was still considered possible that the skeleton was "someone else" who, by coincidence, happened to have the same medical problems as Richard III, died from similar wounds, and was buried at the right time in Richard III's grave, by mistake or deliberate charade. The DNA match only made this already unlikely hypothesis practically impossible.
So, again, with the same logic we might perhaps be able to strengthen the hypothesis "Rudolph II owned the VMS", or weaken even further the hypothesis "John Dee owned the VMS".
But I don't see how DNA analysis could help us
identify the Author of the VMS -- even if and when we can recover and sequence some DNA trapped under the ink. We may find a few thousand living people with matching DNA, but they will be scattered all over the world. We may find a few hundred skeletons of people who died in the 1400s that also match. If we are lucky, those skeletons will all be from the same town in Switzerland or whatever. But, even then, we could not conclude that one of them was the VMS author, could we?
By the way, any such DNA would be much more likely to come from the Scribes
or from the workers who manufactured the vellum, who handled it much more extensively than the Author may have done before the writing.
