more differences between the resource bases of adjoining groups,
the greater the intensity of interaction. This first form of variability
is requisite to all highly developed market economies. ;
The second form of variability results from the reliability of
resources within each territory, and the number of kinds of
resources being relied upon at any one time. Inter-group interaction
increases (1) in relation to population pressure on the availableresources; and (2) according to the degree of resource reliability,
increasing when the resource base is less reliable, or relatively
unpredictable. Inter-group interaction decreases when resources _
are more reliable. Averaging the effects of resource fluctuation
charactertizes all economic systems to some degree. :
Given the relationships between population size, resource
variability, and inter-group interaction, it is possible to hypothesize —
that economic behavior varies between populations as a result of
the efficient adaptation of each population to its Particular ©
environmental arrangement

Inter-group interaction results in harvesting more than the a
members of the local group can consume, the production of — q
exchange goods, and the transportation and marketing of
materials. All these activities require an increase in energy §
expenditure. Therefore the intensity of interaction is not normally j
greater than is necessary for group maintenance. Of considerable . j
interest in this discussion is the fact that the village populations in
the Chumash area spoke several related dialects. In 1769, the year .

The plant communities are more similar to those found in Centr:
California than to those of Southern California. The islands have
_ less than half as many plant species as the mainland. At the time of
