Comment on I don't envy the humans pre-dentistry

Nah.
There seems to be a genetic variation that eliminates some or all wisdom teeth. It arose in Asia so long ago that the people who populated North and South America also had it. And in most populations it is still not very prevalent (less than 50%). Despite having been around for ages.
My mom only had the lower two wisdom teeth, none on top.

I don’t follow the logic. Human teeth would be better if more children died? That “quality check” only applies if an organism dies before mating, which happens usually around teenage years for humans.
