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 ...

These "total monsters of fishes" are extinct today, though new clues about their lives come from CT scans and their closest ...

The sensitive interior of human teeth might have originated from a seemingly unlikely place: sensory tissue in fish that were swimming in Earth’s oceans 465 million years ago. While our teeth are ...

The Atlantic wolffish is known for its powerful bite, capable of crushing hard-shelled prey with ease. Now, researchers have ...
