Final answer:
North American Native societies were organized by clan-based structures and communal land ownership, experiencing conflict over resources and significant alteration in their way of life due to European colonization and the introduction of individual land ownership.
Step-by-step explanation:
The organization of North American Native societies, including their military, political, and economic aspects, was primarily by clan-based structures and communal land ownership. These societies were often organized into small autonomous clans or tribal units that adapted to their specific environments, which could lead to conflict over hunting and fishing territories. European colonization introduced the notion of individual land ownership, resulting in conflicts as Natives began to lose control of their territories. The transition in land ownership also altered the traditional lifestyle and governance of Native Americans, as they came in contact with European colonial policies and concepts.
