#todayILearned that whales descended from a land mammal that looks like a dog. It walked on land and swam in the water. It had hooves and webbed feet, and eyes that were set high on its skull.
Its name is Pakicetus—the whale from Pakistan—because that’s where their fossils were found.
This sounds like an April Fool’s joke, but it isn’t.
