Evolution of Wisdom?

Ok, So I was getting my teeth cleaned the other day at the dentist when they decided that it was about time for my wisdom teeth to be coming out. They took me to the X-ray room and did a full mouth x-ray. When the dentist came back he was kinda of confused and asked if I had already had them removed and I told him no. SO the dentist told me that I was a very rare case because I was born Without wisdom teeth. I told my father about this and he said that he was born without them also. I'm sorta confused about the whole idea and wondered if anyone has heard of this before or knows anything about it...

Do a google search on wisdom teeth.

i was born with only two wisdom teeth, one in the upper right and one in the bottom left quadrants of my mouth.

i wouldn't doubt that more and more humans will be born without wisdom teeth eventually, but considering that natural selection isn't much of a factor for humans, it might take a while.
