I think this proves the smartest, most ambitious people are always moving on down the road. The ones who stayed in Namibia have sure not evolved much.
Before I’m asked, yes I’ve been there.

I’d state the matter differently. The people who left were certainly more ambitious, but they may have included a mixture of the smart and the dumb.In fact, the average IQ of the departing group could have been exactly the same as the average IQ of the folks who stayed back.
Then over the course of the long and arduous journey, the dumb ones were less likely to survive. So by the end of the journey, the people who remained were likely to have been both smarter and more ambitious than the folks who stayed back in the old homeland.
