Spanning time and space, humans have formed institutions that model marriage in modernity, to declare and formally define a relationship between individuals. Dominant evolution theory explains that procreative interests led to the labeling of man and woman as husband and wife. When investing valuable energy in the vulnerable stages of pregnancy and motherhood, women need a loyal partner to provide food, shelter, and protection. On the flip side, a man wants to know his time and effort are not futile. Love, says evolutionary anthropologist D.M. Buss, is understood through action.
Sex is our behavioral link with procreation and the maintenance of a species.
This physical connection, and not the emotional, subjective definition humans have created, is the basis for love. Then, even if this theory proves true, thousands of years of cultural evolution creating a standard of emotional socialization may now overwhelm our basic, biogenetic composition. The Soviet Union's past reveals how problematic it is to find any absolute when looking for love. Although American misconceptions may lead us to believe we're looking for love in all the wrong places, sexual themes abound in Soviet's literary work throughout times of censorship. Marxist ideology praised divorce.
