Describe the process as civilizations in Africa changed from Hunter and Gatherer communities to civilizations.

It is a prehistoric period.

Explanation:

In this context, it is a transition from the Old Stone Age (Paleolithic) to the Late Stone Age (Neolithic). In the Neolithic, people formed permanent settlements and organized evenings of a social community. In this context, they are tied to one place.

People in the Paleolithic led a nomadic life, but in the Neolithic, they saw the advantage of forming a particular place and creating organized communities.
