Excerpt:

I should note here that while there is a definite social structure built around various strategies of mate guarding, these social mores and familial repression of women’s Hypergamous impulses does, in fact, stem from evolved, behavioral adaptations.

Kin Affiliation Across the Ovulatory Cycle : Females Avoid Fathers When Fertile Consider that girls will make subconscious efforts to avoid their fathers during the proliferative phase of their ovulatory cycle. Also, consider girls enter puberty at an earlier age when their fathers are not present in the family. Both of these are examples of phenomena that have a physical manifestation and a latent evolutionary purpose, but socially we build moral/social frameworks around buffering for (or sometimes accommodating) them.

Likewise, there are social controls that span all cultures that have the same purpose of buffering against the predations and mechanics of women’s Hypergamous natures. The most stringent of these might be repressing of women’s sexuality, but the latent purpose is still the same; controlling for paternity assurances.
