Do Women Have Evolved Adaptation for Extra-Pair Copulation?

Abstract

Do women have special-purpose evolved adaptation that functions in pursuing copulations with men other than the main romantic partner, just as they have specialized adaptation for seeing color, estimating object distance, digesting fat, responding to stress, and a multitude of other problems that gave rise to successful selection for functional traits in human evolutionary history? This question can be asked in a variety of other ways without change in its conceptual content: do women have a feature(s) that is functionally designed/organized to accomplish extra-pair copulation (EPC)? Do women have a trait(s) that has the evolutionary purpose of extra-pair copulation? Do women have a bodily feature(s) that resulted in net reproductive success (RS) during human evolutionary history because its female bearers were conditionally unfaithful in their romantic relationships? Did human female ancestors become ancestors (i.e., out-reproduce the females that failed to become human ancestors) in part because they were infidels in romantic relationships?
