First, they tracked the evolution of the head scales during the embryonic development of the Nile crocodile, which lasts about 90 days in total. While the skin covering the jaws remains smooth ...

Parallel evolution is a lot more elegant and a lot more powerful, since it shows that adaptive brainstorms don’t have to be one-offs, but could happen again and again, in place after place, as ...

Crocodilians make up the group of creatures that includes crocodiles, caimans, alligators and gharials. Now, new genetic studies have revealed their unusually slow rate of genetic evolution.

Of all the reptiles alive today, crocodiles may be the least changed from their prehistoric forebears of the late Cretaceous period, over 65 million years ago ...

The fossil remains of a previously unknown species of crocodile that lived 40 million years ago has been unearthed in an Australian lake bed, researchers say. The almost complete skulls, one lower ...

Crocodiles once flourished on land and in the oceans as a result of fast evolution, researchers suggest. Modern crocodiles are predators living in rivers, lakes and wetlands – grabbing fish ...

Crocodiles are the closest living relatives of birds but compared with their feathered cousins are stuck in the past, new research has shown. Both groups share a common ancestor that lived around ...
