I have a hypothesis that several million years ago just about anything could mate and have offspring with anything else. For example, the modern beaver is probably the offspring of an early human and a bear that was slow to snap out of hibernation. That's just a guess. But the next time you see a beaver standing on his back legs eating a fish, try to imagine him as a buck-toothed tourist at a sushi place. It's easier than it should be.

This guy is seriously making me laugh tonight.
