All the Cats, Explained
From MinuteEarth, a quick tour of all the different kinds of cats in the world, extinct, wild, and domesticated, and how they are related to each other. Some interesting facts I learned:
The saber-toothed tiger was the largest cat to ever live and researchers now believe it had a short tail rather than a long one.
There was an American cheetah. It was bigger than the cheetah we know today and “almost as fast”. It went extinct around the time humans showed up in North America.
Leopards and snow leopards aren’t actually that closely related.
Domestic cats are mostly descended from wildcats (not to be confused with cats who are wild — wildcat refers to two specific species, the European wildcat (Felis silvestris) and the African wildcat (Felis lybica)).
