scientists wondered for a long time just how whales are related to land mammals, especially the largest land mammal, the elephant. They believed there must have been some kind of in-between mammal that lived partly in the sea and partly on the land. They had no evidence for such an animal, however, until the discovery of the bones of an animal scientists have called “Pakicetus.” This large mammal, which was alive 50 million years ago,
could not swim but it could run very fast.
live on the land but found its food in the water.
was totally different from both elephants and whales.
lived in the deep ocean water and ate mostly fish
