A trade-off between tooth size and jaw mobility has restricted fish evolution, Nick Peoples at the University of California ...

A new study has revealed that teeth, as we know them today, didn’t evolve for chewing or biting, but for sensing the ...

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.

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 ...

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 ...

The predatory fish have 500 pointy teeth in multiple rows, which they use to latch onto their prey and shred them into digestible bits. And in order to make sure their chompers are up to the ...

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 ...

A big catch of fish fossils in southern China includes the oldest teeth ever found, researchers say. The findings may help scientists learn how our aquatic ancestors got their bite. The finds ...

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.

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 ...
