Cetaceans and anthracotheres

Tee hee! I don't see much similarity between a hippo and a whale, but here's what they're saying:

Whale and hippo 'close cousins'

"A water-loving mammal that lived 50 to 60 million years ago was probably the 'missing link' between whales and hippos, according to a new analysis ...

"Jean-Renaud Boisserie, Michel Brunet and Fabrice Lehoreau found that the semi-aquatic ancestor of whales and hippos split into two groups: cetaceans and the anthracotheres.

"Cetaceans eventually spurned land, lost their legs and became fully aquatic.

"The pig-like anthracotheres, flourished over 40 million years and died out less than 2.5 million years ago. They left only one descendent, the hippopotamus.

"The study places whales firmly within the cloven-hoofed group of mammals known as Artiodactyla, which includes cows, pigs, sheep, antelopes, camels and giraffes."
