I can't dispute the dating of the die off. 70,000 is good for me. The 450,000 yr date is when the scientists say the mytochondrial DNA originated apparently as a mutation. Our dates are compatible with each other. The survivors of the die off 70,000 yrs ago were all descendants of the woman whose Myto-DNA is shared by all of us today. Extrapolating from Darwin, probably some particular characteristics of that particular strain of myto-DNA conferred some survival advantage at the time, along with location on the planet (Africa) that allowed her descendants to be the only members of the species fitted enough to survive the conditions during the die off in the "survival of the fittest" postulate of Darwinian evolution.

I think that the info on myto-DNA I am basing my conclusions on, may have come from the NYT Science section of several days ago If it is there and still available for free, I will post the link, though later rather than now.
