This study uses agent-based modeling to show how individual decisions by women in hunter-gatherer societies can lead to population stability. Cultural rules, like marriage practices, also impact group resource access and population dynamics.

Area of Science:

  • Social Sciences
  • Anthropology
  • Computational Social Science

Background:

  • Understanding the link between individual behaviors and societal patterns is crucial in small-scale societies.
  • Hunter-gatherer groups provide unique insights into social dynamics and population regulation.

Purpose of the Study:

  • To explore the relationship between micro-level decision-making and macro-level societal outcomes in small-scale societies.
  • To investigate how culturally framed choices influence population stability and resource dynamics.

Main Methods:

  • A multi-agent simulation was developed to model social interactions and decision-making processes.
  • The simulation used the !Kung San (African hunter-gatherer group) as a case study, incorporating cultural rules on birth spacing and marriage.

  • Data from Australian hunter-gatherer groups were used for comparative analysis and validation.

    • Main Results:

    • Population stability emerged as an emergent property from micro-level decisions on birth spacing, influenced by resource density.
    • Cultural rules regarding incestuous marriages led to macro-level outcomes of inter-camp marriages.
    • Inter-camp marriages significantly impacted resource access and overall population dynamics.

    Conclusions:

    • Micro-level cultural decision-making, particularly by women regarding birth spacing, can drive macro-level population stability in hunter-gatherer societies.
    • Cultural marriage rules have significant macro-level consequences, affecting resource distribution and population dynamics.
    • Agent-based modeling is a valuable tool for understanding emergent social phenomena in anthropological contexts.
