What Is Human and Where Did Humanness Come From?
When did humans evolve you know well not yet so we talk about the rise of modern humanity and what's happened in the last 50 or 60 years. We've smeared out humanness to mean many different things it's not just upright posture upright posture goes back at least five million years tool use went back at least two and a half million years stone tool years but since wasps and chimpanzees use tools then it's got to be even older than that. I'm interested how have different notions of what is human influence our theories of human origins.
