Nor were the ancient relatives of whales that you see pictured on this tree — such as Pakicetus. Hippos likely evolved from a group of anthracotheres about 15 million years ago, the first whales evolved over 50 million years ago, and the ancestors of both these groups were terrestrial. These first whales, such as Pakicetus, were typical land ...
Learn how whales evolved from land-dwelling mammals to fully aquatic creatures over millions of years. Discover the fossil discoveries that revealed the origin and diversity of cetaceans, and how they challenged Darwin's theory of evolution.
Increased evidence on whale evolution shows that modern whales diverged from ancient forms around 34 million years ago, with whale diversity peaking during the Miocene Epoch, 23 to 5 million years ago, and then decreasing until now.
