What fossil organism is in whale evolution?

The evolution of whales was a gradual process in which terrestrial animals have become more and more adapted to an aquatic environment. Ambulocetus was perhaps the first whale ancestor that live mostly in water. Evidence suggesting this are the sediments where its fossils where recovered.

15. How do the fossils of whales provide evidence that whales have evolved over millions of years. Fossils of the stages of whale evolution have been discovered that clearly indicate their sequence of change from land dwelling mammals.

What was the first whale?

Odd as it may seem, a four-footed land mammal named Pakicetus, living some 50 million years ago in what we know as Pakistan today, bears the title of “first whale.”

What animal evolved into a whale?

Meet Pakicetus, a goat-sized, four-legged creature that scientists recognise as one of the first cetaceans (the group of marine animals that includes dolphins and whales). How Pakicetus’ descendants evolved into whales is one of the most intriguing evolutionary journeys known to science.
