>>However, if age-dating these finds reveals that the specimens were emplaced contemporaneously with surrounding sediments, then we will have to re-think our current theories.<<
It seems to me that all that would need to be re-thought is the assumptions about the timing of genetic variations in mitochondrial DNA.
Older human skeletons push the timeline further backwards but don't, in and of themselves, change the well-established pattern of genetic variation of mitochondrial DNA, which clearly supports a single origin traceable back to Africa.

Mitochondrial evidence does indeed support African roots, but let's see what further investigation reveals.

mitochondrial DNA..The premis assumes that man originated in Africa, I was disgusted with the theory when I read about it in The Scientific American. This is another tautolgy.
