- Population growth: As a hunter-gatherer band grows in size, they may find that their current territory can no longer support them adequately and decide to split into two or more groups, with one migrating and setting up a new settlement.
- Social conflicts: Tensions and disputes within a hunter-gatherer group can arise for various reasons, such as unequal distribution of resources or disagreements over hunting strategies, leading to conflicts that compel one or more groups to leave and establish new settlements.
-Exploration and curiosity: Hunter gatherers may be driven by a desire to explore and discover new lands, expanding their territories by building settlements in previously unexplored regions.
