The First Teeth Grew on the Skin of 460-Million-Year-Old Fish and Were Never Meant for Chewing
Even the gentlest sip of a cold drink can send a jolt through our teeth. That familiar sting, long thought to be a side effect of enamel wear, might instead hint at something far more ancient — the ...
The next time you wince from an ice-cold drink or a too-hot slice of pizza, blame your ancestors. Specifically, the armor-plated fish that swam Earth’s oceans over 460 million years ago. A new study ...
Our modern teeth evolved from a most unexpected source. A new study, published on May 21 in the journal Nature, has revealed surprising information about the origins of human teeth. Our teeth evolved ...
Teeth first evolved as sensory tissue in the armored exoskeletons of ancient fish, fossil scans find

A study published in the Nature journal alters how the evolution of fish has been historically understood. Fossilized fish and other sea creatures have often been pivotal in new scientific discoveries ...
The sound of a dentist's drill - did it make your teeth quiver? Well, it turns out the sensitivity of our teeth which causes them to ache can be traced back to the exoskeletons of ancient armored fish ...
Long ago, some saltwater fish adapted to freshwater — and in doing so, developed an extraordinary sense of hearing rivaling our own. By examining a 67-million-year-old fossil, researchers from UC ...
The cichlid fish of Africa's Great Lakes have formed new species more rapidly than any other group of vertebrates. A new study shows that the ease with which these fish can develop a biological ...
