Yep, we see humans acting like animals and animals acting like humans wherever we chose to draw that conclusion and yet some find it so hard to believe that we have common ancestors. In my personal opinion the only difference between humans and all the other animals is genetic. If you heard a story about a woman actually cannibalizing her husband while they had sex you might think it's one of the most disgusting and depraved things you've ever heard, until you read the whole story and found out it was a pair of praying mantises. They get a pass for it and we still think they're cool as hell catching bugs by the porch light. Find me a sick depraved act of human behavior and I'll find something similar in the animal kingdom and vice versa. Animal or human, there's not really much of a distinction at all. I used to think maybe it was air conditioning. That could be the point where we became something special. Then I read about termite mounds.
