- 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.

This article explores determinants of non-classical polyandry, which the authors assert is more common than is usually conveyed. Results indicate that societies with non-classical polyandry tend to be small scale and egalitarian, practice hunting and gathering or horticulture, and have a male-skewed sex ratio. Overall polyandry is thought to add to the reproductive fitness of both men and women.

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.

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.
Related Hypotheses Cite More By Author - Subsistence based primarily on hunting-gathering will be associated with extensive kinship systems, whereas agropastoralism will be associated with intensive ones (384).Walker, Robert S. - Marrying kin in small‐scale societies, 2014 - 4 Variables
The authors examine degree of intensiveness (kin-relatedness) among foraging and agropastoralist societies, predicting that hunter-gatherers will pursue more extensive kinship networks in order to maximize residential options in the case of unpredictability or uneven geographic distribution of food resources. Support is found for the hypothesis, and it is suggested that while extensive fission-fusion dynamics are beneficial in foraging systems, the increase in cooperation in large-scale agricultural settlements is aided by norms which encourage kin marriage and relatedness.
