Think of it this way: why has evolution designed us to get wisdom 
teeth that won't fit in our mouths (if all the other teeth are still 
there) at 18? Wisdom teeth are big suckers; you have to figure that 
modal human experience during the deep time in which mouth evolution 
takes place had us losing *8* adult teeth by the time we were 20...
