They found that the DNA sequence of the sperm whale and pygmy sperm whale were more closely related to the baleen whales than to other toothed whales and dolphins. The study also showed that the beaked whale (which has only a few teeth) is only distantly related to any other whale or dolphin. Stated in science article by Koen De Smet. Not plagarized.
