Hypothesis
Societies with less predictable environments will have more daily food sharing norms than those with more predictable environments.
Note
d = 0.24 and posterior probability = 0.32 for precipitation; d = 0.71 and posterior probability = 0.11 for temperature; d = 1.3 and posterior probability = 0.01 for NPP predictability.
