Research the two civilizations that you did not describe in this week’s Discussion Board. • First, discuss why you think the two civilizations developed where they did. o For example, why would civilization develop in the northeast corner of Africa but not farther west? o What role did rivers play in the development of civilization? o Was climate a factor in early civilizations? • Compare and contrast the two civilizations you have chosen in these three areas: political structures, writing, and the organization of their society.
