[Marxism] Tweaking of DNA dating on human evolution

Why I find the new date for the last big "out of Africa" pulsing of
human population is that Toba (74,000-75,000 years ago) made any
earlier migration (70,000 to 80,000 years ago) rather moot, because it
wasn't likely to survive and there would have been much room for
growth over some time afterwards.  There's some controversy as to
whether any human populations outside of Africa survived.

The "tweaked" years for that last big push "out of Africa" (55,000 to
60,000 years) also places it a bit closer to that global "cultural
revolution" revolution in tool making (and, by implication, much else)
around 45,000-40,000 years ago.
