Scientists have long suspected that the eardrum evolved separately in mammals and diapsids, the taxonomic group that includes reptiles and birds. However, because the eardrum cannot be fossilized, this theory could not be proved through the fossil record.
Modern humans developed chins not for chewing or other mechanical functions, but as the result of an evolutionary adaptation involving face size and shape that may be linked to changes in our hormone levels due to domestication, according to a new study.
The world’s largest living amphibian, the Chinese giant salamander (Andrias davidianus), is capable of feeding not only on prey located directly in from of it, but also on creatures which approach from the side, thanks to a newly-discovered quick-strike technique.
A distinctive 200-million-year-old fish used a combination of jutting front teeth and pebble-shaped rear teeth to feed on bivalves and other hard-shelled creatures it could find from the sea floor, according to new research from the University of Bristol.
A two-faced fish more than 400 million years old is likely the last common ancestor of all jawed vertebrates--including us--and provides additional evidence that sharks are not primitive creatures, as had long been assumed.
A new fossil from Madagascar reveals fascinating perspectives on the growing diversity of Mesozoic mammals.
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.
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...
