  • The origin of whales and their transition from terrestrial life to a fully aquatic existence has been studied in depth. Palaeontological,, morphological and molecular studies suggest that the order Cetacea (whales, dolphins and porpoises) is more closely related to the order Artiodactyla (even-toed ungulates, including cows, camels and pigs) than to other ungulate orders. The traditional view that the order Artiodactyla is monophyletic has been challenged by molecular analyses of variations in… CONTINUE READING
