Because if we were descended from a single pair of individuals, the 'clock' on our mitochondria, our somatic chromosome DNA and our sex chromosome DNA should read about the same.

As I read the Bible, in any case, we should have common descent from Noah, who should be our last common paternal ancestor; and the major racial trifurcation should occur within one generation at the time of the sons of Noah. None of this is compatible with human genetics. The closest we get to recent common somatic chromosome ancestry is the bottleneck between 50 and 100 thousand years ago, and nobody thinks that bottleneck was two individuals, one male, one female.

Not if "mitochondrial Eve" had progenitors, which seems to be the case. Right?

From what I've read, "mitochondrial eve" and "chromosonal Adam" don't prove anything, one way or the other, regarding the ultimate origin of the human race.

If the story of Noah is literally true, which seems doubtful, as far as I know. It's an open question for Catholics.
