Our sensitive teeth originally evolved from the "body armor" of extinct fish that lived 465 million years ago, scientists say. In a new study, the researchers showed how sensory tissue discovered on ...

The sensitive interior of human teeth might have originated from a seemingly unlikely place: sensory tissue in fish that were swimming in Earth’s oceans 465 million years ago. While our teeth ...

Scientists have long debated where teeth came from. One idea was that they evolved from small bumps on the tough outer shells of ancient fish. These bumps, known as odontodes, were once a mystery.

So she looked at the tooth-like scales of the embryos of sharks, skates and catfish — and she found nerves. Combined, these results suggested that the armor of ancient fish likely allowed them ...
