Cetaceans, the group including whales and dolphins, originated in south Asia more than 50 million years ago from a small, four-legged, hoofed ancestor. Now, researchers reporting the discovery of an ancient four-legged whale-found in 42.6-million-year-old marine sediments along the coast of Peru-have new insight into whales` evolution and their dispersal to other parts of the world. The findings are reported in the journal Current Biology on April 4.
