Desert island: How climate can promote speciation

Article Abstract:

Paleontologists have excavated fossils of giant amphibians Nigerpeton ricqlesi and Saharastega moradiensis in the Saharan sands that indicate that climate can effectively isolate organisms and thereby foster endemism. These creatures inhabited oases dotting a similar desert landscape 250 million years ago, feeding on fish as well as other aquatic tetrapods.
