I read article last night at The Atlantic that referred to an idea that hunter-gatherers used their teeth harder to chew rough foods (harder than the agriculture types later) so maybe their jaws didn’t line up with overbite like ours now so maybe they didn’t have “f” & “v” “labiodental” sounds—which theory would be a challenge to linguistics, which has had this idea that there aren’t new basic sounds—originalism?
