Why do we have wisdom teeth?

Wisdom teeth were the evolutionary answer to the need for chewing power to combat excessive wear. Today, our diets are not as rough as those of our ancestors. With modern marvels like forks, spoons, and knives, as well as softer food, the need for wisdom teeth is virtually nonexistent.

What purpose do wisdom teeth have?

Once essential for an early human diet of roots, leaves, meat, and nuts, wisdom teeth are no longer totally necessary. Today, humans cook food to soften it, and we can cut and crush it with utensils. Anthropologists believe humans have evolved beyond needing wisdom teeth, so some people may never get any.

Why do we have wisdom teeth if they have to be removed?
