#3The San people of southern Africa are claimed to be the living human group with the most ancient divergence from the rest of humanity, around 200,000 years ago. That they are so similar to the rest of humanity has always made me wonder if the commonly accepted divergence date ranges should be pushed back.
From the Wiki:
"A DNA study of fully sequenced genomes, published in September 2016, showed that the ancestors of today's San hunter-gatherers began to diverge from other human populations in Africa about 200,000 years ago and were fully isolated by 100,000 years ago, well before the first archaeological evidence of modern behaviour in humans."

Do you know if they are related to the Berbers?

I guess evolutionary change is gradual so it's hard to have a cut off date for when pre homo sapien ancestors had kids that counted as homo sapiens. The origins of cooking going back 1.9 million years implies the ancestors must have been a bit human like. https://www.theguardian.com/science/2011/aug/22/cooking-orig...

Evolution is not single speed. For a relatively static population with no need to change their lifestyle it will run more slowly. For a dynamic population with bottlenecks it can run very quickly.

Seems rather unlikely, given their appearance.

#8I wish they'd go into more detail about how the shape of the brain case affects brain organization. Does anyone have a good layman-oriented source on that?
Edit: it looks like both are affected by differences in brain development. https://www.mpg.de/623578/pressRelease201011021

#10I've never really grasped where the surprise comes from with these kinds of discoveries - we know that our ancestry always had the potential to give rise to lines that look very much like us, since we look very much like us. Why should it be a surprise if it happened more than once? We're looking at a terribly long timescale, after all - at least by comparison to our recorded history.
