The ancestors of whales are thought to have lived on land about 50 million years ago. The name of the animal that became the ancestor of this whale is Pakicetus.
Pakicetus is a four-legged animal that was originally the size of a goat. However, different from the other four animals, he is able to navigate the ocean with his reliable swimming ability.
In addition, pakicetus is claimed by scientists to be the world’s first ‘cetacean’ animal. Cetaceans are a group of marine animals that include dolphins and whales or marine mammals.
Pakicetus is described as living on the shores of lakes and rivers around ancient Pakistan and India. These animals hunt small land animals and freshwater fish. This is because the ferns have the ability to hear sounds when they are underwater.
With this ability, researchers think if pakicetus travel to great distances again. This is what makes pakicetus evolve and adapt to their surroundings.
The evolution of pakicetus into a whale was very slow. With this change, Pakicetus was claimed to have turned into a whale as it is today.
The evidence for this claim is by studying the anatomy, DNA, and biogeography of the whale itself. The results of this study also found that whales are very closely related to these land animals.
