One of the most important advancements in human evolution has been agriculture.  We no longer had a need to be nomadic and move seasonally to forage for food.  We realized that seeds + earth + water and sun will yield a crop.  Where you have sustainable crops, you have a city.  Where you have a city, you have commerce.  Where there is commerce, there is wealth, trade, and prosperity.
