Actually, sharks undoubtedly evolved from prehistoric sea-based creatures that were predators and had sharp teeth. Just as we know about dinosaurs, there is also fossil evidence that shows the existence of these sea creatures, about 200 million years ago. Gradually, these creatures evolved into what we know today as the various kinds of sharks. But it is unlikely we will know where the very first one of these creatures came from or where it lived.
