Free or Despotic? The Distribution of Hunter-Gatherer Ethnolinguistic Groups in California
Author(s): Timothy Dennehy
How do hunter-gatherers divide their landscape into territories? In this paper, I will delve into results from a prior study showing a significant difference in territory size between coastal and inland groups in California (Dennehy et al. 2014). I will first simulate territory sizes and locations using an Agent-Based Model (ABM) of hunter-gatherer bands. The model will draw on human behavioral ecology to simulate distribution of foraging groups under three different conditions of social organization: an Ideal Free Distribution (IFD), Ideal Despotic Distribution (IDD), and a hybrid where both forms are possible. "Ideal" here refers to agents that have perfect knowledge of the suitability of different patches in their environment. Such agents are "free" when they can come and go from any patch as they please; they are "despotic" in cases where social hierarchies exist that allow a patch’s current inhabitants to successfully defend it from newcomers. I expect each condition to produce a different distribution of forager groups, visualized as maps of simulated territories. I will then compare these maps to that created by Alfred Kroeber (1922) to test which condition more accurately matches the known distribution of California foragers.
