Ancient DNA is always valid evidence.
For what and over what period pf time?
Genetic drift can remove genes over time, what sort of time scale would we be looking at?

Hi Roy -

For who was where when, at all points in time.

While rates of human genetic drift are unknown now, some very large impacts affected human evolution, and some day they will be used to
accurately determine the rates of human genetic drift.

An interesting example of the rate confusion this now causes is the claim by some that A, B, C, and D differentiated in the Americas and simultaneously in Asia, while an earlier differentiation in Asia with differentiated groups migrating to the Americas appears to have been the case.

But why do we continue to assume west to east in the case of one lone skeleton?
Was it a ceremonial burial?
Even if it was, was it typical of the time and place?
He could have been on a lonely trip, leaving no DNA in his wake, from a southern population center,
Up the west coast of NA.
It is, after all, just one skeleton, not a graveyard.
Do I see traces of the Kennewick Man argument here?
