American Journal of Human Biology • Published In • Pages: 1-8 •
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.
