The Reading / Listening - Human Teeth - Level 0

Researchers have found how humans got teeth. They say teeth came from an ancient fish 400 million years ago. They used the strongest X-ray machine in the world to study a fossil of the fish. The fish was inside rock. Researchers found that the fish's teeth were very similar to human teeth.



The fish was one of the earliest with teeth. A researcher said its jawbone is very similar to ours. He said: "When you grin at the bathroom mirror in the morning, the teeth that grin back at you can [follow] their origins right back to [that fish]." Another researcher was surprised to "find teeth so deep on the evolutionary tree".
