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.

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.

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 tests several hypotheses related to the presence or absence of polygyny. Results suggest a negative relationship between polygyny and male provisioning, and positive relationships between polygyny and warfare, interpersonal aggression, and pathogen stress.

This chapter examines the role of male and female ornamentation. Several hypotheses concerning mating systems and ornamentation are empirically tested; several are supported.
