There is an underlying prescription to being human. As a species we are intelligent, omnivorous, tribal and highly resourceful and it was these attributes have allowed us to dominate the planet. Humanoid history goes back millions of years, and our particular species Homo sapiens spread from Africa approximately 50,000 thousand years ago.
Many evolutionary psychologists argue that we have not substantially changed, either physically or psychologically, since then.
