Post-Neolithic Diet-Induced Dental Changes Led to Introduction of ‘F’ and ‘V’ Sounds | Sci.News

A class of speech sounds that is now present in nearly half of the world’s languages -- labiodentals, produced by positioning the lower lip against the upper teeth, such as in ‘f’ or ‘v’ -- are a relatively recent development, one brought about by post-Neolithic diet-induced changes in the human bite. That’s according to a paper published in the March 15, 2019 issue of the journal Science.

Link for the Science research article. The observation that societies without access to softer food kind of avoided labiodentals is old, from 1985, but the research is recent-ish (2019).

    My favourite bit of this is the comment at the bottom of the page that just says “doubt it”. So glad scientific discourse is alive and well.
