We really are just animals. Just look at us, "wife swappers" governed by our sexuality, violent, predators and prey, hunters and gathers. Our intelligence is irrelevant we're just a bunch of animals. We are nothing more than intelligent and attractive apes in human form.
In fact if you threw a giant party and invited several monkeys a lot of people would probably feel right at home. When you cut to the chase and get to the bottom of things, what we really are/ in simplicity, without all the cake, we're just animals.
Apes in clothes, with table manners.
