Many people consider human intelligence to be the most advanced compared to other animals - "It's what sets us apart from the beasts." I'm not so sure. I think it's safe to say we have the most complex and perhaps possess a higher level of reasoning, but these traits evolved, as with animals, as a means of survival. As animals evolved to survive - to eat, breed, take flight or fight - they developed traits that can leave mankind in the dust. The sensory capabilities of, say, sharks or birds as an example, and the intelligence required to process those sensory inputs can far exceed any of our capabilities. So, it's always interesting when we find animals engaging in actions that seem to imply a level of thinking far beyond what we would normally associate with that species. We're always a little surprised when an animal acts like us. The classic example was the belief that the use of tools was a major divider between mankind and the animal kingdom. At least it was a widely held belief until researchers like Dr. Jane Goodall and others documented chimpanzees and other monkeys and apes not only using rudimentary tools to assist in the pursuit of food, but that they also pass along those techniques to their offspring.
