Natural selection modified the attachment-behavioral system to bond adult mating partners in early members of the genus Homo, thus facilitating increased investment, especially paternal investment, in offspring. Previously existing adaptations that fostered inter-sexual conflict (e.g., ovulation adaptations) could have threatened attachment bonds; therefore, the attachment-behavioral system might have evolved the ability to mute or refocus such adaptations for the purpose of strengthening the bond. Two studies offer support for this prediction. Women who were strongly attached to their romantic partner revealed positive associations of fertility with reports of romantic physical intimacy, but these associations were negative among unbounded women. This mode-rational effect of attachment bond strength was robust beyond dis-positional attachment anxiety and avoidance, relationship satisfaction, relationship commitment, and partner physical attractiveness, none of which revealed robust mode-rational effects. Findings highlight how researchers can use the time-line of hominid evolution (i.e., phylogeny) as a tool to complement functional, adaptation hypotheses.
