Wikipedia, the free encyclopedia says, "Wisdom teeth are vestigial third molars. In earlier times, when tooth loss in early adulthood was common, an additional molar had the potential to fill in a gap left by the loss of another tooth. It has also been postulated that the skulls of human ancestors had larger jaws with more teeth, which were possibly used to help chew down foliage to compensate for a lack of ability to efficiently digest the cellulose that makes up a plant cell wall. As human diet changed, a smaller jaw was selected by evolution, yet the third molars, or "wisdom teeth", still commonly develop in human mouths."

∙ 14y agoGood question. Because that's the way God made us? Animals have primary teeth also.
Primary teeth are small to fit the jaw and oral cavity size of little beings. As we grow, our mouths, jaw, head etc get bigger so we need bigger teeth.
