Another example of animal intelligence is the raven. By doing this the raven is able to drink form the jug. Ravens actually do this from time to time. It seems unlikely to most biologists that instinct could lead to such a process. A great example to animal intelligence is the grizzly bear.
Bears are smart enough to realize when they are being tracked.
Bears will go through great trouble to hide their tracks by walking on rocks, rivers, or back tracking, rather then walk through snow, or grass. While humans may never know what the majority of the animal kingdom knows we can be certain they know something. The question is how much they know. Animals may have little more then a push past instinct, but it is something. In the essay What the Animals Know, Mr. Peterson ends his discussion with an amazing story.
