Paleontologists have uncovered new fossil evidence suggesting that chewing—an ability long thought to have evolved much later—may have emerged as early as the middle Jurassic period, when dinosaurs dominated the landscape. The discovery challenges previous assumptions about when animals first developed the mechanical adaptations needed for breaking down food. Researchers examined plant-eating species to trace the origins of this crucial evolutionary trait. If confirmed, the findings could reshape understanding of early dinosaur diets and behaviors.
It's likely you've already chewed and swallowed some tasty morsel today. But when did that ability emerge? New evidence points to at least the middle Jurassic, back when dinosaurs still reigned.
