What is one reason early clans of hunter-gatherers are not considered civilizations?
they did not have art of any kind.
they hunted animals for food.
they made use of the resources around them.
they did not build towns or cities.

I believe the answer is: They did not build towns or cities.

There are 3 basic criteria for a civilization:

- It must has a permanent place

- It must have people as members of the civilizations

- It must has some sort of government that regulate the people

Hunter gatherers move from one place to another in order to find foods and other resources needed by the group. This mean that they do not have permanent place to settle down. Because of this, hunter gatherers cannot be considered as a civilization.

julius caesar turned the roman republic into the roman empire by coming in and taking the "dictator" role during the time of a civil war (elites vs lower classes) winning battles and reputation, then declaring him dictator for life

hope this : )

assessment is the missing word
