Did whales really evolve from wolves?
The traditional hypothesis of cetacean evolution, first proposed by Van Valen in 1966, was that whales were related to the mesonychids, an extinct order of carnivorous ungulates (hoofed animals) that resembled wolves with hooves and were a sister group of the artiodactyls (even-toed ungulates).

How did Basilosaurus and Squalodon whales evolve?
Another extinct whale called Squalodon, a fossil dolphin with a wicked smile full of triangular teeth, similarly hinted that whales had evolved from meat-eating ancestors. Like Basilosaurus, though, Squalodon was fully aquatic and provided few clues as to the specific stock from which whales arose.
