There is much more to many animals than we might care to admit, you can see it in their eyes.
We humans have the ability to learn, to reason and solve problems. We’re self-aware, and we’re also conscious of the presence, thoughts and feelings of others. We make tools and practice the art of deception. We’re creative. We think abstractly. We have language and use it to express complex ideas. All of these are arguably signs of intelligence. Scientists may not agree on the best and fullest definition of intelligence — but they generally agree that humans are highly intelligent.
Other members of the animal kingdom exhibit signs of intelligence as well, and some scientists might say the definition of animal vs. human intelligence is merely a matter of degree…
(Note: of course I didn’t include humans in the video, what would have been the point? Except flattering an already oversized ego…)
