Ancient civilizations had very different diets than we do today. Instead of driving to the grocery store, our early ancestors hunted and gathered whatever food they came across in nature.
Snacking on raw foods such as leaves, roots, nuts, and meats was hard on their teeth! In those days, dental hygiene was poor, and tooth loss was common.
By the time a person had reached his or her 20s, it was not unusual to have lost a tooth or two to decay. Without enough teeth, ancient people would not have been able to chew the foods they found and risked starvation.
Anthropologists believe that in order to survive, early humans developed wisdom teeth as a way to make chewing easier, even if they were missing other teeth.
Luckily, our present-day diet, lifestyle, and access to dental care have made survival much easier on modern man — and on our teeth! This means wisdom teeth are no longer considered necessary for our survival.
As a result, some evolutionary biologists now classify wisdom teeth as “vestigial organs,” which means they are no longer considered to have a functional purpose.
In fact, biology may agree. Researchers have found that 35 percent of the modern population never develops wisdom teeth at all, suggesting that over time they will disappear completely
