Hypothesis

The exponent of the scaling relation between camp area and population size will vary between 1 and 2.

Note

According to the model presented by the authors, it is expected that, due to proximity tensions and the carrying capacity of the environment, the area of a hunter-gatherer camp will increase exponentially for every addition to the population. The authors test this by using an ordinary least squares model to test all hunter-gatherer societies, and then generalized least squares models to control for ecology type, regional group, and culture type.
