Detailed explanation-1: -Wisdom teeth are vestigial (unnecessary) features of our bodies. Wisdom teeth removal has become a rite of passage for many teens and young adults around the globe. But if your wisdom teeth erupt in alignment with your other teeth and don’t cause any problems, you may not need to do anything.

Detailed explanation-2: -Our Early Ancestors Needed Wisdom Teeth Because early humans needed to chew coarse, hearty foods, they required a broader jaw. Wisdom teeth grew in to give them more chewing power for this purpose. Because the jaw was wider, the wisdom teeth were able to grow in with no difficulties.

Detailed explanation-3: -Fossils indicate that the first few generations who lived on earth had molars that were much larger in size. Evolution changed this pattern somewhere down the line and the first molars became the largest in the set. As we continue to evolve, studies indicate that future generations will have no wisdom teeth at all.

Detailed explanation-4: -With a reduction in human jaw size, molars-particularly the third molars, or wisdom teeth-became highly prone to impaction. Increasingly, wisdom teeth are congenitally absent. As a consequence, they are now considered a vestigial feature of the human body.
