Throughout most of human history, people lived in relatively small, egalitarian bands. With the advent of farming, stratified societies began to emerge and today dominate the human landscape. For this question, explain Diamond's thesis as to: A. Why these stratified societies were forced to emerge in the first place. B. What are Diamond's and Harris's arguments on why stratified societies are still necessary today and C. explore, using Diamond's rational behind strata (the 'four ways'), how our current strata is maintained.
