Lower-jaw teeth in frogs re-evolved after an absence of 200 million years, a new study says. The discovery challenges a "cornerstone" of evolutionary thinking, according to experts. Of the more ...

Frog teeth have little to do with defense. They are sometimes used in “traumatic mating,” but a study into the evolutionary loss and gain of teeth among frogs found that diet appears to be the ...

Nearly all frogs lack teeth on their lower jaw, but some, such as Budgett's frogs, have evolved lower fanglike structures that allow them to inflict puncture wounds on their prey.

Guenther’s marsupial frogs have a full set of teeth, defying evolutionary theory. This adult specimen, small enough to fit in your palm, is from the University of Kansas Museum of Natural History.

The Florida Museum of Natural History found that frogs lost and regained teeth over 20 times in their evolution. That’s more than any other vertebrates (animals with spines).

Frogs have lacked teeth on their lower jaw since their first appearance in the fossil record more than 200 million years ago. But scientists were finally able to verify one species defies the ...

GAINESVILLE, Fla. --- Scientists have long known that frogs are oddballs when it comes to teeth. Some have tiny teeth on their upper jaws and the roof of their mouths while others sport fanglike ...

Researchers analyzed CT scans of nearly every living amphibian genus to reveal that frogs have lost teeth over 20 times during their evolution, more than any other vertebrate group.

Researchers from the Indian Institute of Science’s (IISc.) molecular biophysics unit in a study have identified that peptides (short protein) produced from Budgett’s frog can combat enzymes of ...
