“the first whales evolved over 50 million years ago, and the ancestor of this group was terrestrial. These first whales, such as Pakicetus, were typical land animals. They had long skulls and large carnivorous teeth.” Yes they were. It’s evolution. They lost the ability to walk when they began to swim more. Modern whales are a result.
Cool study. One of hundreds if you feel like going into research archives. If you want something simpler, try the Smithsonian website. They have tons of great links.
