The Origins of Cetaceans

It is well-known that cetaceans, including whales, porpoises, and dolphins, are mammals. They possess lungs for breathing instead of gills, and they give birth to live offspring. Their streamlined forms, lack of hind limbs, and features like the fluke and blowhole highlight their connection to terrestrial mammals. However, unlike sea otters and pinnipeds (seals, sea lions, and walruses), visualizing the appearance of the first whales is challenging. Fossil records reveal extinct cetaceans that were fully adapted to marine environments. How did the transition from a terrestrial mammal to a swimming whale occur? Until recently, fossils demonstrating a clear intermediate stage between land mammals and cetaceans were lacking.

Significant discoveries have finally enabled scientists to piece together the origins of cetaceans. In 1979, a team in northern Pakistan uncovered what turned out to be the oldest known fossil whale. This fossil, named Pakicetus in honor of its discovery location, was found in river deposits dating back 52 million years. The river that formed these deposits was situated near the ancient Tethys Sea.

The fossil comprises a complete skull of an archaeocyte, an extinct lineage related to modern cetaceans. Although only a skull was found, it offers valuable insights into cetacean origins. The skull resembles that of cetaceans, yet its jawbones do not feature the enlarged cavity filled with fat or oil that modern whales use to perceive underwater sounds. Pakicetus likely detected sounds through its ear openings, similar to land mammals. Additionally, the skull lacks a blowhole, another adaptation found in cetaceans for diving. Nevertheless, certain characteristics indicate that Pakicetus represents a transitional form between extinct carnivorous mammals called mesonychids and cetaceans. It is believed that Pakicetus fed on fish in shallow waters and had not yet evolved for life in the open ocean, likely breeding and giving birth on land.

Another significant find occurred in Egypt in 1989, where several skeletons of an early whale named Basilosaurus were discovered in sediments once part of the Tethys Sea, now exposed in the Sahara desert. This whale existed around 40 million years ago, 12 million years after Pakicetus. Many incomplete skeletons were recovered, including for the first time a complete hind limb with three tiny toes. These legs would have been too small to support the 50-foot-long Basilosaurus on land. Basilosaurus was undoubtedly a fully aquatic whale, possibly possessing nonfunctional or vestigial hind limbs.

An even more thrilling discovery was reported in 1994, also from Pakistan. The now-extinct whale Ambulocetus natans ("the walking whale that swam") inhabited the Tethys Sea 49 million years ago, approximately 3 million years after Pakicetus and 9 million before Basilosaurus. The fossil includes a substantial portion of the hind limbs, which were robust and ended in long feet resembling those of modern pinnipeds. These legs were functional both on land and in water. While the whale retained a tail and lacked a fluke, it swam similarly to modern whales by moving its rear body up and down. The large hind limbs aided propulsion in water, while on land, where it probably bred and gave birth, Ambulocetus may have moved akin to a modern sea lion. It clearly linked terrestrial life with marine existence.
