Study shows aquatic origins of modern birds

Reconstruction of the Early Cretaceous (110-115 million year old) amphibious bird Gansus yumenensis, in a lake in what is now the Changma Basin, northwest China's Gansu Province. A set of 110-million-year-old fossils from China is the earliest example of a modern-looking bird and strongly suggests ancestors of all living birds were waterfowl, researchers said June 15, 2006.
