New Fossils Resolve Whale's Origin

Recent fossil finds from Pakistan overturn the picture of whale evolution long championed by paleontologists, bringing them closer to agreement with an alternative view proposed by molecular biologists. The discoveries establish a close evolutionary link between cetaceans, which include whales, dolphins, and porpoises, and a group of mammals known as artiodactyls. These hoofed animals with an even number of toes include cows, sheep, goats, pigs, deer, and hippopotamuses.
