Final answer:
S cientists believe about New Stone Age that A. They lived in small groups.
Step-by-step explanation:
Scientists and archaeologists generally believe that during the New Stone Age, or Neolithic period, communities were characterized by small, agrarian societies. This era marked a significant shift from nomadic, hunter-gatherer lifestyles to settled agricultural practices. Neolithic people were among the first to engage in systematic agriculture, cultivating plants and domesticating animals, which contributed to the establishment of more permanent settlements.
Living in small groups allowed for more effective management of resources within the limited technological and organizational capacities of the time. These communities typically focused on subsistence farming, cultivating crops like wheat and barley and domesticating animals such as goats, sheep, and cattle.
While Neolithic people were skilled in crafting tools and artifacts from stone, wood, and bone, the evidence suggests that advanced technologies like writing or chariot warfare were developments associated with later periods, such as the Bronze Age. The emphasis during the Neolithic era was on adapting to a more sedentary lifestyle based on agriculture, gradually paving the way for more complex societal structures and technological advancements in subsequent ages.
