recently, at a local bar, it was brought to my attention that not all people believe in evolution. so to prove that evolution is real and people and all animals evolve i present the example of wisdom teeth. if it were not for the advances in dentistry, a larger number of people that develop wisdom teeth would die from impacted wisdom teeth (ie. they become infected, etc). thus people who did not form wisdom teeth would become a higher and higher percentage of the population. evolution.
