Sabia que a nova geração tem tendência a não ter dentes do siso ?
Humans are still evolving, and the proof is hidden inside our own mouths. Scientists have discovered that our faces are slowly becoming smaller over generations, and this shrinkage leaves less space for certain teeth—especially wisdom teeth. Long ago, our ancestors had larger jaws because their diet was tough and raw, full of roots, nuts, and uncooked meat. Bigger jaws were necessary to chew this food, and wisdom teeth had plenty of room to erupt. But as humans learned to cook and process food, chewing became easier, and our jaw size began to shrink.
The problem is that evolution works slowly. Even though our jaws have reduced in size, our genes still try to form the same number of teeth. This mismatch causes wisdom teeth to erupt with no proper space, leading to impaction, swelling, and pain. In fact, recent studies show that more and more people are being born without wisdom teeth altogether—a sign that evolution is actively reshaping us.
What seems like just a dental problem is actually part of a bigger scientific story: our anatomy is changing before our eyes. The disappearance of wisdom teeth may be one of the clearest signs that human evolution never really stopped.
