When did whales first evolve from land mammals?
Quick Answer
Whales began evolving from land-dwelling mammals about 50 million years ago.
The Full Story
Whales evolved from land mammals during the early Eocene, around 50 million years ago. Transitional fossils such as Pakicetus and Ambulocetus show step-by-step changes from land walking to life in water. Over time, their limbs became flippers and their tails became powerful swimming tools. Modern whales are therefore fully aquatic mammals with a terrestrial ancestry.
