The Hunterian Museum at The Royal College of Surgeons of England in London has this fascinating medical specimen on display that shows what a child’s skull looks like when its adult teeth are waiting in the wings. It won’t be long before those deciduous (baby) teeth are booted out.

I agree. At what point in evolution did we get 2 rows of teeth, and what was the benefit?
