Extrapair Sex

Because of their heavy ohligatory investment in offspring and limited off-
spring number, ancestral women faced the challenge of securing sufficient
material resources for reproduction and gaining access to good genes. We
review evidence indicating that selection produced two overlapping suites of
psychological adaptations to address these challenges. The first set involves
coupling
—the formation of social partnerships for providing biparental care.
The second set involves
dual mating,
a strategy in which women form long-
term relationships with investing partners, while surreptitiously seeking
good genes from extrapair mates. The sources of evidence we review include
hunter-gather studies, comparative nonhuman studies, cross-cultural stud-
ies,
and evidence of shifts in women's desires across the ovulatory cycle. We
argue that the evidence poses a challenge to some existing theories of human
mating and adds to our understanding of the subtlety of women's sexual
strategies.
Key Words:
dual mating, evolutionary psychology, ovulation, relationships,
sexual strategies.
