Ancient River Inference Explains Exceptional Oriental Freshwater Mussel Radiations

Abstract The concept of long-lived (ancient) lakes has had a great influence on the development of evolutionary biogeography. According to this insight, a number of lakes on Earth have existed for several million years (e.g., Baikal and Tanganyika) and represent unique evolutionary hotspots with mul...
