But fish don't have limbs — at least most of them don't — in the way that we have limbs," Cohen said. "And so having this many teeth helps them not only chew through their food and bite ...

A new study has revealed that teeth, as we know them today, didn’t evolve for chewing or biting, but for sensing the environment around ancient fish. This discovery pushes the timeline of ...

Paleontologists have long believed that teeth evolved from the bumpy structures on this armor, but their purpose wasn’t clear. The new study, published this week in Nature, confirms that these ...

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 ...

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 ...

Their evolutionary precursors are thought to be hard structures called odontodes which first appeared not in mouths but on the external armour of the earliest fish around 500 million years ago.

“The normally have a pretty good dental plan.” The fish – which can also be found in the Great Lakes, according to Nature Conservancy Canada – can weigh up to 35 pounds and can live for at ...
