Final answer:
Farming societies are less fluid than foragers due to ties to land, division of labor into specialties, and the development of private property and inheritance, which create rigid social hierarchies and a stationary accumulation of wealth.
Step-by-step explanation:
Farming societies are less fluid in membership than those of food foragers because agriculture ties people to specific parcels of land. This need for land, combined with agricultural surpluses and associated division of labor into specialties like artisans or traders, encourages individual accumulation of property and wealth. These factors lead to social hierarchies based on asset ownership, inheritance, and specialized roles within a society, which in turn limit social mobility and reinforce more rigid social structures.
The notion of private property was less prevalent among food foragers as they had more mobile, egalitarian social structures. Because their subsistence strategies did not focus on stored surpluses or land tenure, forager societies avoided the development of the farm-based social hierarchies. Furthermore, as the primary gatherers in their societies, women in foraging groups often had significant say in decisions such as relocating their camp, leading to a more diffuse distribution of authority.
