How would you describe the diffusion of civilizations in Africa and the Near East?

The high antiquity of civilization in the Middle East is largely due to the existence of convenient land bridges and easy sea lanes passable in summer or winter, in dry or wet seasons.

Large-scale desert travel was limited to special routes in Iran and in North Africa, both east and west of the Nile Valley.
