Movement of People
The
initial formation of these civilizations is based on the movement of
peoples into the river valleys and plains. These people were
nurtured by these spaces. They often described their environments as
god-like and characterized their nearby rivers as life-giving. The
transformation of these valleys and plains into to places capable of
physically nurturing the various peoples who moved into them was one
of the first acts of cultural innovation and exchange. A simple
illustration of this exchange is seen in the technologies of food
production. The types of food in a region, where the food could be
grown, and, under what conditions, all gave rise to innovation.
