Although chimps are the most biologically similar compared to humans, they act nowhere like us. Compared to us, they?re rather cordial creatures. In my experience, I would say rats or mongooses are probably most like us. Rats in the sense that we are practically everywhere and anywhere and refuse to die out and mongooses in the sense that we are a destructive invasive species that can be both compassionate and cruel to each other. So what do you think? Or did I make a bad analogy?
