Many people have suffered from impacted third molars, also known as wisdom teeth.

But there are also a lucky few who are missing a wisdom tooth or two (or even all four). Why do some people have wisdom teeth, while others don't?

Some thousands of years ago, a random mutation arose which suppressed the formation of wisdom teeth, a trait that then spread and now accounts for the lack of wisdom teeth among some modern humans.

Impacted third molars (teeth that do not make it out of the gums) can become infected, leading to serious health problems. Even more commonly, however, wisdom teeth cause severe pain.

Should these people be considered more highly evolved? Maybe. There's no known evolutionary advantage NOT to have wisdom teeth.

And with modern medicine, there's little change for natural selection to weed out people with wisdom teeth because people just take them out instead of dying from complications with them.
