By Ellsworth, Ryan M., Shenk, Mary K., Bailey, Drew H., Walker, Robert S.

Hypothesis

Pair-bond instability (proxy measure being higher incidence of maternal half siblings) will be greater where male contribution to subsistence is lower. (2)

Note

Horticulturalists should exhibit the highest fraction of maternal half-siblings and agropastoralists the lowest.
