The Origins Of Cetaceans 鯨類動物起源 (1)
It should be obvious that cetaceans-whales, porpoises, and dolphins-are mammals. They breathe through lungs, not through gills, and give birth to live young. Their streamlined bodies, the absence of hind leg, and the presence of a fluke and blowhole cannot disguise their affinities with land dwelling mammals. However, unlike the cases of sea otters and pinnipeds (seals, sea lions, and walruses, whose limbs are functional both on land and at sea), it is not easy to envision what the first whales looked like. Extinct but already fully marine cetaceans are known from the fossil records. How the gap between a walking mammal and a swimming whale bridge? Missing until recently were fossils clearly international, or transitional, between land mammals and cetaceans.
