Why crocodiles have changed so little

Recommended Posts

Crocodiles today look very similar to ones from the Jurassic period some 200 million years ago. There are also very few species alive today – just 25. Other animals such as lizards and birds have achieved a diversity of many thousands of species in the same amount of time or less.

Prehistory also saw types of crocodile we don't see today, including giants as big as dinosaurs, plant-eaters, fast runners and serpentine forms that lived in the sea.

In the new research, published today in the journal Nature Communications Biology, the scientists explain how crocodiles follow a pattern of evolution known as 'punctuated equilibrium'.

God bowled a strike. Followed up by a spare with alligators, and caymans. He was having a good day.:D He then finished the game with one. Last. Rock.
