Wisdom teeth? What's so wise about them anyway?

Most people get strife with their wisdom teeth. A lot end up having them out. Why? Why have we been cursed with these meddlesome teeth? Will no one rid us of these turbulent teeth? (Well yes, obviously oral surgeons)

The answer, as usual, is Modern Diet. An ancient, pre-farming, diet was high in fibre and low in energy. HUGE amounts of chewing were required to extract every last calorie. Constant chewing caused the contact points of the teeth to wear, the teeth moved forwards to take up the wear, space developed at the back, the wisdom teeth came through without drama, more chewing surface was created. GREAT SUCCESS!

As it says down there ↓, 'Eat like a caveman'.
