Our teeth evolved from the piercing “body armor” of extinct fish, which existed about 465 million years ago. The study explained how sensory tissue found within the exoskeletons of the fish ...

A new study reveals that the sensitivity of teeth, which makes them zing in a dentist's chair or ache after biting into something cold, can be traced back to the exoskeletons of ancient, armored fish.

True teeth are only found in backboned vertebrates, like fish and mammals. Some invertebrates have tooth-like structures, but the underlying tissues are completely different. This means 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 on ...

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. CNN values your feedback 1.

"We performed experiments on modern fish that confirmed the presence of nerves in the outside teeth of catfish, sharks and skates," Haridy told AFP. This shows that "tooth tissues of odontodes ...

Yara Haridy, an evolutionary biologist at the University of Chicago, likes to stun people by telling them that our skeletons evolved from a jawless fish. "Much of what we have today has been ...

Dentin, the sensory tissue inside teeth, first evolved in the armored exoskeletons of ancient fish, serving as a sensory organ rather than for feeding. Fossil evidence shows these structures ...

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 ...

So Haridy turned to ancient vertebrate fish whose bumpy exoskeletons scientists believe evolved into our teeth. "As fish evolved a jaw and started to feed more like predators," she says ...
