Whale ancestors began living full time in the water around 50 million years ago during the Eocene epoch. These early cetaceans, such as Pakicetus, gradually adapted to aquatic life, evolving features suited for swimming. Over millions of years, they transitioned from land-dwelling mammals to fully marine creatures, leading to the modern whales we see today.
