Civilizations are marked by complex divisions of labor.
Civilizations are marked by complex divisions of labor. This means that different people perform specialized tasks. In a purely agricultural society, members of the community are largely self-sufficient, and can provide food, shelter, and clothing for themselves. In a complex civilization, farmers may cultivate one type of crop and depend on other people for other foods, clothing, shelter, and information. Civilizations that depend on trade are specially marked by divisions of labor.
