Latest Jaw Stories
Despite having retained their basic "sharkiness" for millions of years, modern sharks have less to tell us about the early evolution of jawed vertebrates—including humans—than was previously thought.
A study published on Wednesday in the journal Nature has revealed new details on the evolution of the jaw – a major defining structure in the evolution of the face.
Scientists have used genetic data to create a comprehensive evolutionary family tree, or phylogeny, for “spiny-rayed fish," a category that encompasses about a third of all living vertebrate species. They were quite surprised to find out just who was related to whom in the fish world.
Imagine a 25-foot-long shark, but instead of having a typical set of jaws, it packs a chainsaw-like ‘tongue’ full of razor-sharp teeth ready to slash through prey with ease.
It’s likely the question “how long have humans had teeth?” has never entered into many normal and sober minds. Scientists and, more specifically, odontologists, are a different breed, however, and have wondered about the origins of teeth for many years.
Scientists studying one of New Zealand’s most iconic reptiles have found that it chews its food in a way unlike any other animal on the planet, challenging the popular perception that complex chewing ability is linked to high metabolism.
Arthritis, an often debilitating joint disorder that affects millions and millions of people around the world, may have also caused pain and discomfort for dinosaurs and other ancient reptiles more than 150 million years ago.
The history of evolution is periodically marked by explosions in biodiversity, as groups of species try out a wide range of shapes and sizes. With a new analysis of two such adaptive radiations in the fossil record, researchers have discovered that these diversifications proceeded head-first.
A new study has found that many of the orthodontic problems faced by people in industrialized nations are due to their soft modern diet.
Scientists have identified a critical step in the evolution of filter-feeding whales' enormous mouths.
The Angler, (Lophius piscatorius), also known as the Fishing-frog, Frog-fish, or Sea-devil, is a species of monkfish in the family Lophiidae. It is found in coastal waters of the northeast Atlantic, from the Barents Sea to the Strait of Gibraltar, the Mediterranean and the Black Sea. This species comprises a significant commercial fishery in parts of its range. The Angler has a very large, broad head that is flat and depressed. The rest of the body appears to be a mere appendage. The wide...
