Hypothesis
Percentage of subsistence derived from agriculture will be positively associated with indicators of environmental favorability (65).
Note
No linear association is found with any environmental variables. However, some relationships may be curvilinear, with highest dependence on agriculture occurring in middling ranges of precipitation and evapotranspiration.
