Why did whales lose their legs?
In findings to be published this week in the Proceedings of the National Academy of Sciences, scientists say the gradual shrinkage of the whales’ hind limbs over 15 million years was the result of slowly accumulated genetic changes that influenced the size of the limbs and that these changes happened sometime late in …

Are whales dinosaurs?
The Origin of Whales or the Evolution. The first whales appeared 50 million years ago, well after the extinction of the dinosaurs, but well before the appearance of the first humans. Their ancestor is most likely an ancient artiodactyl, i.e. a four-legged, even-toed hoofed (ungulate) land mammal, adapted for running.

Why did whales go back into the ocean?
Vertebrates evolved in the sea and eventually moved onto land. The ancestors of whales later returned to the sea, taking advantage of its rich food supplies. As early whales adapted to their new marine surroundings, a diversity of species evolved.
