Afram genius John McWhorter displays his brilliant powers of reasoning:
We are to take from this that evidence for an artistic mindset - i.e. modern, abstract thought - mysteriously "exploded" into the human endowment at this time. "The Big Bang," some call it, an apparent Great Leap Forward in toolmaking, burial rituals and art among European peoples at this time. Scholars of human evolution have taken a cue from this and supposed that the Big Bang was the result of some genetic mutation that led to humanity of a modern cognitive level.
[. . .] but if this "Big Bang" happened in Europe, then presumably this dramatic mutation did not happen to people beyond Europe. And yet, it is assumed that all human beings are equal in basic mental endowment [. . .]
The Big Bang idea has always seemed peculiar to me, then, in an implication surely none of the scientists intended but which stood there anyway: a Victorian idea that only Europeans became truly civilized while everyone else in the world remained "natives" chanting around cooking pots in forest clearings.
