He found that teeth evolved from simple to complex around 86 times across all fish species and that these transitions were common in African cichlids, which adapted with a certain ease of evolution.

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 ...

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 ...

This fish must have a good dentist. A Brazilian businesswoman Paula Moreira went viral earlier this week after she shared images of a fish sporting human-like teeth. The video, which has more than ...

Ray-finned fish are a diverse and widespread group, representing 99% of living fish species. Two key adaptations have helped them thrive: large teeth and extendable jaws.

Nervy human teeth arose from ancient armored fish scales The sometimes uncomfortable sensations we feel in our teeth may be an evolutionary holdover from the scaly exteriors of ancient armored 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.

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.

A new study shows that the ease with which these fish can develop a biological innovation (complex teeth), not just the innovation itself, enables this rapid evolution. Credit: Nick Peoples, UC Davis.
