  1. Pair-bond instability (proxy measure being higher incidence of maternal half siblings) will be greater where male contribution to subsistence is lower. (2)Ellsworth, Ryan M. - Comparative study of reproductive skew and pair-bond stability using genealo..., 2015 - 2 Variables

    Authors use genealogical data to investigate pair bond stability and reproductive skew across a sample of 80 small-scale societies. Results suggest that male reproductive skew and pair-bond stability are independent sources of cross-cultural variation in human mating patterns.

  7. Pair-bonds are more supportive of lactation than are other kin relations (88).Quinlan, Robert J. - Human lactation, pair-bonds, and alloparents: a cross-cultural analysis, 2008 - 6 Variables

    This study examines the relationship between pairbonds and lactation, specifically the relationship between pairbond stability, alloparenting, and cross-cultural trends in breastfeeding. Findings show that both conjugal stability and availability of alloparental care are associated with age at weaning.

  8. The presence of older siblings who are potential helpers will have a positive effect on child survival (11).Sear, Rebecca - Who keeps children alive? A review of the effects of kin on child survival, 2008 - 2 Variables

    Evolutionary anthropologists have long emphasized the puzzle of short inter-birth intervals, extended childhoods, and long post-reproductive lives of humans, in particular the problem it poses for raising children. While there is agreement that mothers receive assistance from kin to offset the high costs of raising children, opinion is equivocal as to which kin help and to what extent they help. Here the authors review 45 studies from historical and contemporary natural fertility populations to assess the effects of various types of kin on child survival rates.

  9. Pair-bond stability will be positively associated with importance of male provisioning (153).Quinlan, Robert J. - Evolutionary ecology of human pair-bonds: cross-cultural tests of alternativ..., 2007 - 2 Variables

    This study tests three hypotheses on the evolution of the human pair-bond: male-provisioning, male mating competition, and the defense of offspring from other males. Findings indicate that male provisioning and mating competition are factors in the development of the pair-bond. Additional findings indicate that alloparentling, polygyny, and equal contribution to subsistence by each sex contribute to the security of the pair-bond.
