Final answer:
Sites occupied by mobile hunter-gatherer groups are characterized by food evidence, temporary houses, and mobility.
Step-by-step explanation:
Sites occupied by mobile hunter-gatherer groups are characterized by different kinds of remains. These remains include food evidence such as hearths, pottery containers, animal bones, coprolites, and tools used in food processing. Additionally, the remains may include baskets or pottery used for storing food, garbage dumps, and shell middens.
In addition to food remains, other characteristics of these sites may include temporary houses made of wood, bone, and flint, as well as evidence of fishing using dugout canoes.
The most common feature of mobile hunter-gatherer groups is their mobility, often moving in seasonal cycles over broad territories and regularly meeting up with other groups at specific spots for resources.
