Evolutionary theory predicts that sexual coercion and rape are likely to occur in any species in which males are more aggressive, more eager to mate, more sexually assertive, and less discriminating in choosing a mate (Thornhill & Palmer, 2000). McKibbin and Shackelford (2011) state that males of many species have evolved strategies to sexually coerce and rape females. It is for this reason that researchers have speculated that several female traits or behaviors evolved to reduce the risks of being raped (McKibbin & Shackelford, 2011). The rationale behind the proposed experiment examined whether parents’ childrearing practices and women’s plasticity during childhood may have influenced the development of psychological mechanisms in response to the recurrent adaptive problem of rape. Analyses showed that maternal support during childhood predicted how frequently rape-avoidance behaviors were exhibited by women as adults. Analyses also showed that father absence was related to earlier sexual activity but age of menarche did not predict and was not associated with any rape-avoidance behaviors.
