There are lots of ways that humans are different from the rest of the animal kingdom: we have those mighty opposable thumbs, for example — mind you, so do many other animals, especially our primate relatives like gorillas and chimpanzees — and we walk around on our hind legs all the time. But what has really separated us is our big brains.
Humans are, without a doubt, super smart animals. We can do long division, send electrons from one place to another, and some of us can even parallel park — not me, personally, but I've seen it done before.
But there are other smart animals out there that should really have us re-thinking our high esteem of ourselves, and we can probably add another to that list now.
