The one I was thinking of is the (hypothesized) reduction in jaw size due to less need for powerful chewing, while teeth stayed the same size leading to many problems

Yeah. I remember a story about an anthropologist who went to a indigenous tribe, IIRC somewhere around the pacific, he took photos of everyone’s teeth. Everyone had straight teeth from the kids to the elderly. Then a generation later someone else did the same thing. Went to that tribe and took photos. Many kids had crooked teeth. The only thing that changed is that they adopted a Western diet.

Can’t remember the name of that anthropologist, though.
