In South America, nomadic hunter-gatherer societies and agricultural village societies differed significantly in their social organization, settlement patterns, and economic foundations.

Settlement and Economy

Nomadic groups relied on hunting, fishing, and gathering wild plants, which necessitated constant movement within prescribed territories to avoid exhausting local food supplies. Because they lacked agriculture and permanent food surpluses, they could not establish large, permanent settlements or accumulate significant material wealth. In contrast, agricultural societies developed in favourable environments where the cultivation of crops—such as corn, beans, and squash—supported larger, stable populations and the construction of permanent villages and towns.12345

Social Organization

Nomadic Societies: These groups were typically organized into small, widely scattered units, such as extended family groups or bands. Social differentiation was minimal, based primarily on age and sex rather than complex economic or political status.23
Agricultural Societies: As agriculture and other technologies were adopted, social and cultural systems became increasingly complex. These societies often featured more elaborate social hierarchies, public works, and specialized roles, which were absent in the simpler, more egalitarian structures of nomadic groups.425

Over time, as agricultural communities expanded, nomadic peoples were often pushed into agriculturally marginal areas.24
