Piranhas belong to a family of bony fish characterized by highly developed dentition. They’re cousins to the pacu fish, which has dentition eerily similar to human teeth. Unlike pacu teeth, which are ...

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.

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 ...

Teeth evolved from sensory organs in ancient fish, not for chewing. Odontodes, the precursors to teeth, appeared on fish armor 500 million years ago Modern fish exhibit nerve sensitivity in ...

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.

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.

Teeth first evolved as sensory organs, not for chewing, according to a new analysis of animal fossils. The first tooth-like structures seem to have been sensitive nodules on the skin of early fish ...
