Is it true there once was a whale called a pakicetus that used to walk on four legs and that's the evolution of whales?
Yes, the pakicetus is an extinct genus of early cetaceans, the group of marine mammals that includes modern whales, dolphins, and porpoises. This animal lived in what is now Pakistan during the early Eocene period, about 50 million years ago. Despite their whale-like appearance, the pakicetus had a number of characteristics that suggest they were not fully aquatic. For example, they had four legs and feet, and they had a long tail that they used for locomotion.
The pakicetus is considered to be one of the earliest known cetaceans. Its discovery in the 1980s provided important evidence for the theory that whales evolved from land-dwelling mammals. Since then, scientists have discovered a number of other early cetaceans, and these animals have helped to fill in the gaps in our understanding of whale evolution.
