A trade-off between tooth size and jaw mobility has restricted fish evolution, Nick Peoples at the University of California Davis, US, and colleagues report in the open-access journal PLOS Biology .

A new study published in 'Nature' has determined that human teeth evolved from the same "genetic toolkit" as an extinct species which lived about 465 million years ago.

However, the sensitive parts inside the hard enamel first evolved for something quite different. New research from the University of Chicago shows that dentine, the inner layer of teeth that transmits ...

Paleontologists have long suspected that our teeth evolved from bumpy structures called odontodes on the exoskeletons of prehistoric fish—but they didn’t understand exactly what these bumps ...

You May Have Sensitive Teeth Because of This 465-Million-Year-Old Fish Learn why both human teeth and an ancient fish contain a key sensory substance — but in different locations.

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 ...

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