Early Human History
We often view ourselves as separate from Nature, but here is the rub: our cultures have changed. Our behaviors have changed. Our diets have changed. Our medicine has changed. But our bodies are the same, essentially unaltered from 6,000 generations ago. Our bodies remember who we are. They respond as they have long responded, unaware that anything has changed. ~ American biologist Rob Dunn
Like their evolutionary forbearers, hominins have always been gregarious. Their earliest exploits, prior to any written record, can only be conjectured from old bones and hoary artifacts. Evidence suggests social behavior patterns that continue to this day. Only the level of technology changed much.
