Summary:
- Paleontologists have discovered the true purpose of the first teeth in the fossil record, which are over 465 million years old.
- These ancient teeth were not used for eating, but rather as a tool to grasp and manipulate prey, similar to how modern-day insects and crustaceans use their mouthparts.
- This discovery provides important insights into the evolution of early life on Earth and how organisms adapted to their environments over millions of years.
