From land to water: The origin of whales, dolphins, and porpoises. Evolution: Education & Outreach 2:272-288. Compared to other early whales, like Indohyus and Pakicetus, Ambulocetus looks like it lived a more aquatic lifestyle. Its legs are shorter, and its hands and feet are enlarged like paddles.
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.
The descendants of Dorudon went on to evolve into modern whales. About 34 million years ago, a group of whales began to develop a new way of eating. They had flatter skulls and feeding filters in their mouths.
Not long after the true identity of Basilosaurus was resolved, Charles Darwin’s theory of evolution by means of natural selection raised questions about how whales evolved.
Whales have existed for millions of years. Watch this animation, from the Sant Ocean Hall , to see how they evolved from land-dwellers to the animals we know today. Discover more about whale evolution in our Ocean Over Time interactive.
Enter Indohyus, a small animal about 70cm long that lived 47 million years ago. It was a member of a family of mammals called the raoellids, prehistoric artiodactyls that lived at the same time...
The new research, conducted by Lisa Cooper, Hans Thewissen, and S.T. Hussain, focuses on the early part of whale evolution, from the time of Pakicetus to Ambulocetus.
Scientists have examined myoglobin genes in diving animals from tiny water shrews all the way up to giant whales, and discovered a pattern: In many divers, the surface of the protein has a more...
By 3D scanning the skulls of some 201 species of whale spanning their entire evolutionary history, the researchers have been able to pinpoint the key moments in the evolution of whales and get a glimpse at what ecological factors were influencing these marine behemoths.
Millions of years ago, whales weren't ocean giants, but land dwellers. In fact, their closest living relative is the hippopotamus, hinting at their remarkable transformation over time. This AnimalWised article explores the incredible evolutionary journey of whales and how they transitioned from land to the ocean giants we know today.
