Final answer:
Communities were small during Paleolithic times due to the need for mobility in search of food and the scarcity of resources.
Step-by-step explanation:

Paleolithic communities were typically hunter-gatherer societies, and they had to constantly move from place to place in search of food. Additionally, the scarcity of resources and the constant threat of wild animals made it difficult to sustain large populations.
