Final answer:
Foraging groups are characterized by their mobility and sexual division of labor, with decision-making based on consensus and a flexible and egalitarian social structure.
Step-by-step explanation:
The two basic elements of social organization for foraging groups, often referred to as gatherer-hunter societies, are mobility and a sexual division of labor. Mobility is a hallmark of these societies, as they move across landscapes following seasonal cycles and resource availability, maintaining social networks through shared territories and cross-band relationships. The sexual division of labor is evident in the typical roles assigned to men and women, where men generally engage in hunting and women in gathering, although there is evidence suggesting that women participated in hunting in the past. Both elements contribute to the adaptive strategy of foraging societies and reflect their egalitarian social structure, where decision-making is based on consensus and informal leadership.
