Let’s say there is a $100 note wedged behind a bookshelf just beyond your reach, and beside the shelf is a set of TinkerToys. Even a toddler could probably snap together a few of the sticks to fish the bill out.

From a young age, human children learn that a rattle won't make a noise until it's shaken, and that placing fingers on a hot stove is a terrible idea. New research suggests that wolves, like humans, have a knack for identifying these kinds of cause-and-effect relationships, but that domesticated dogs do not.

Regrettably, none of us will get to be cats. Most of us will never write a published physics paper either, let alone a highly respected one. But somehow, in the 1970s, a phenomenal feline named Chester managed to do all of this under the tutelage of his human, physicist Jack H. Hetherington. He even had a pawesome pen name -- F.D.C.
