Turns out, those grooves on ancient human teeth aren’t proof of the world’s first toothpicks after all. Scientists now say they’re just the result of chewing tough, gritty foods—like wild orangutans do—rather than early dental hygiene. Only 4% of primate teeth showed similar marks, and acidic fruits or hard seeds could be the real culprits. Basically, our ancestors weren’t flossing—they were just eating like animals! #Science #ScienceNews #Evolution
