How farming changed the human smile — and the way we speak
The shift from tough, fibrous foods to processed grains and softer meals after the rise of agriculture reshaped human jaws, resulting in overbites. This change played a major role in language evolution, enabling labiodental sounds like ‘f’ and ‘v’. The study indicates farming societies developed these sounds at higher rates than hunter-gatherer groups.
