Ken might be on to something.

Ken said [ My estimate is that the y tree (leading to today's living
males) went from one male 72,000 years ago to about 1000 or less males
12,000 years ago. ]

Around 72,000 years ago is when Prof. Marean says that the people
in his article who lived at Pinnacle point, South Africa established
the controlled use of fire and also had developed complex cognition.
Do you think that mitochondrial Eve said to Hg A Adam something
like: --- [ Well, now we can cook and make weapons. Let’s go see
what the rest of the world is like. ] ? And thus began the long walk
out?
