Primates. I know they use that term in evolution and republicans don't like that but don't republicans make people feel like primates? Of course, we are, but that is the most basic of the kind of animals we are, being mammals. I mean that seems to be work, being bipedal. Of course some thinking, but none to get out of hand. Just do the job, back and forth, over and over. Just reminded me of our primate ancestors.
