[European] humans had an ape-like bite until relatively recently, with our top and bottom incisors aligned along their edges. With the invention of the fork around 250 years ago, our teeth abruptly switched to the overbite that is common to nearly every human today. ... This same trend appeared 900 years earlier in China, when chopsticks first came into use.
So what I'm wondering is, has anyone tried to look for any evidence of sound-change patterns that may have accompanied these slight shifts of the resting position of the jaw?
