Hippos
Despite differences of appearance and habitat, hippos and whales are first cousins.
An international team of scientists has proposed they share a common water-loving terrestrial ancestor, which lived 50 to 60 million years ago and evolved into two groups: early cetaceans, which became completely aquatic, and a large group of pig-like terrestrial animals called anthracotheres, whose only surviving descendent is the hippopotamus.
