I disagree with Jared Diamond's ideas that agriculture was detrimental to human development.  Even though agriculture provided people with less nutritious diets, and they were subject to famine and droughts, the benefits from community life and advancements that came from it made it worth the cost of poorer health.  Had we not formed farming societies, we might not have advanced technologically and socially the way we have now.  The creation of a system of wealth and class divisions mad people strive to do better and work harder to maybe move up in social class.  Agricultural communities were essential to begin the advancement to classical society.
