Science Caturday: How do you teach your cat about evolution?

Pascal_innerfish_lolFirst, Pascal the cat thought the book was a guide to eating fish. Then, he thought it was a guide to eating Tiktaalik, a fish with leg-like limbs that is closely related to the ancestor of all land-dwelling vertebrates (amphibians, reptiles, mammals, and dinosaurs).

No, Pascal. Your inner fish is the anatomical similarities you have with fish, because you share a common ancestor with them deep in the past. Though you may think you’re a superior being to your pet hooman, you share the same common ancestor with him, from the first life on Earth until sometime in the Jurassic Period, when all mammals were about the size of your cat toys.
