Cetaceans evolved from land-dwelling artiodactyls in early Eocene Indo-Pakistan, with fossil evidence showing intermediate forms like Ambulocetus and Indohyus bridging terrestrial and aquatic life. Major innovations include the transition from teeth to baleen filter-feeding, development of echolocation in toothed whales, and gigantism linked to Plio-Pleistocene ocean cooling and nutrient availability.
