The first whales appeared 50
The first whales appeared 50 million years ago, well after the extinction of the dinosaurs, but well before the appearance of the first humans. Their ancestor is most likely an ancient artiodactyl, i.e. a four-legged, even-toed hoofed (ungulate) land mammal, adapted for running. Cetaceans thus have a common ancestor with modern-day artiodactyls such as the cow, the pig, the camel, the giraffe and the hippopotamus.
