DNA is revealing that many animals once thought to be a single species may actually be several hidden ones. But research on ...

A new genetic study by researchers at Michigan State University reveals that Borneo’s “fanged frogs” may consist of several hidden species, highlighting complex evolution and the importance of DNA in ...

New genetic research suggests a common Southeast Asian frog long believed to be one species could actually be six or seven distinct ones.

Establishing forests can capture carbon and boost biodiversity — but some biomes are a better bet than others, a recent study ...

Earth’s vertebrate diversity may be far richer than anyone realized. A sweeping analysis of more than 300 studies suggests that for every known fish, bird, reptile, amphibian, or mammal species, there ...

Lost fossils reveal that some of the first ocean predators went global astonishingly fast after Earth’s worst extinction.

After years of analysis, the animal turned out to be an entirely new species — one that lived millions of years longer than ...

That visibility comes with scrutiny. Mammals are among the best-studied organisms on Earth - and among the most threatened.

Scientists may have been dramatically undercounting the number of vertebrate species on Earth. A large analysis of more than 300 studies suggests that for every recognized species of fish, bird, ...

Scientists analyzing Bornean fanged frogs found what was once thought to be one species may actually be several genetically distinct species.

Smithsonian researcher Brian Gratwicke and colleagues describe how acoustic technology aided the remarkable rediscovery of four amphibian populations thought to have vanished from Panama’s mountain ...

Mammals are not especially diverse. Roughly 6,800 mammal species are known to exist, compared with about 8,800 species of amphibian, 11,000 species of bird and 12,500 of reptile. Yet when most people ...
