Table knives and forks reshaped European bites
Anthropologist C. Loring Brace found that the modern overbite, where the top incisors overhang the bottom, appeared in Europeans only about 250 years ago, roughly when table knives and forks became common. Before that, people clamped meat in their front teeth and sawed off pieces, which kept the incisors meeting edge to edge; once cutlery pre-cut food into small morsels, the jaw developed differently. Cutlery changed human anatomy, not just manners.
