Prehistoric whales 45 million years ago
The earliest ancestor of whales is a furry quadruped omnivore, which evolved into a series of amphibians about 50 million years ago. Over time, whale ancestors lost the connective tissue between the spine and hind legs, and then the hind legs disappeared completely. Scientists believe that whale ancestor species completely evolved into aquatic organisms about 45 million years ago.
