A new study led by UCC paleontologists discovered that frogs have conserved their ecology in the last 45 million years. 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 ...

Extremes of the colour gradient of the Eastern San Antonio frog (Hyla orientalis). On the left, a specimen captured in Chernobyl inside the high contamination zone; on the right, a specimen captured ...

Paleontologists with the Smithsonian National Museum of Natural History have discovered a previously unknown prehistoric species — a 270 million-year-old amphibian with wide eyes and a cartoonish grin ...

Over the course of 500 million years, three species of poison frogs evolved to withstand a toxin they use to prevent predators from catching them. But, there’s a catch: the frogs experience a ...

Evolution is the result of environmental pressures forcing species to adapt, and few environments exert pressures like the Chernobyl exclusion zone. A new study has revealed evolution in action as ...

The development of hair was of central importance for the evolution of mammals and thus also of humans. However, the evolutionary origin of the genetic program of hair was previously unknown.

Scientists have discovered evidence of a prehistoric species of amphibian that could be the precursor to modern species − and they bestowed upon it the great honor of being named after a green froggy ...

Berkeley -- Picky female frogs in a tiny rainforest outpost of Australia have driven the evolution of a new species in 8,000 years or less, according to scientists from the University of Queensland, ...

Evolution, Vol. 75, No. 12 (DECEMBER 2021), pp. 3203-3213 (11 pages) Dollo’s law of irreversibility states that once a complex structure is lost, it cannot be regained in the same form. Several ...

Australia and South America weren't always so separate. At one time, many millions of years ago, these two continents were connected, along with others, in the southern supercontinent of Gondwana.

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. Scientists have ...
