Mitochondrial "Eve" and Y-chromosome "Adam" are not the Biblical Adam and Eve, so don't worry about how it all fits into Genesis.

[Chris Talk]

I am well aware of that. My comment was just this, that if we are all descended from a "mitochondrial eve" who lived x years ago, then we are also descended from her FATHER, who lived some x+20 years ago.

Similarly, if we are all descended from a "genetic Adam" who lived 60M years ago, we are also all descended from his MOTHER, who lived just 60000+20 or so years ago, and in one swoop you get the two sexes reduced to the same number of years ago.

Elementary, my dear Watson.

None of which invalidates my original point, which is that the story at the head of this thread is trivial, tautological, and hogwash.
