Why do you think that there was no need or desire for any type of social structure among the people of the early paleolithic tribes?

Because they were nomads, they all lived walking to all regions and did not form groups. They were all hunters and there was no division of tasks, so there was no need to define a social structure.

Explanation:

The Paleolithic period is marked by the emergence of the first bipedal men and capes to produce tools that improved their lives. These men were nomads, they were not fixed in one place and therefore did not form groups, which made the establishment of a social structure unnecessary.

For a social structure to be defined, it is necessary that there are groups, a community of people, with different tasks that provide for the existence of society and the division of the group into social structures.
