Hypothesis

Pair-bond instability (proxy measure being higher incidence of maternal half siblings) will be greater in the absence of amassable, heritable resources. (3)

Note

Thus, foragers and horticulturalists will exhibit the highest, and agropastoralists the lowest, fraction of maternal half siblings.
