Hundreds of millions of years ago, fish had sensory features on their exoskeletons that contained dentine, the material that makes our teeth sensitive today ...

Sensory features on the armored exoskeletons of ancient fish may be the reason why humans have teeth that are sensitive to ...

Sharks, skates and catfish also have tooth-like structures called denticles that make their skin feel like sandpaper. When Haridy studied the tissues of her catfish, she saw that the denticles were ...

New research shows that dentine, the inner layer of teeth that transmits sensory information to nerves inside the pulp, first evolved as sensory tissue in the armored exoskeletons of ancient fish.

Learn why both human teeth and an ancient fish contain a key sensory substance — but in different locations.

A new study, published on May 21 in the journal Nature, has revealed surprising information about the origins of human teeth.

Teeth are sensitive because they evolved from sensory tissue in both ancient vertebrates and ancient arthropods.

Teeth are good for chewing and biting, but they are also sensitive – and that may have been their original function hundreds ...

A recent study reveals that human teeth evolved from the sensory armor of ancient fish that lived 465 million years ago.
