Moreover, if an ancestral woman bore a child with this extra-marital partner, she also increased genetic variety in her descendants.

Infidelity had unconscious biological payoffs for both males and females throughout prehistory, thus perpetuating the biological underpinnings and taste for infidelity in both sexes today.

In a previous post I wrote about some of the reasons women might choose to be sexual outside of their primary relationship.

However, monogamy is only part of the human reproductive strategy. Current studies of American couples indicate that 20 to 40% of heterosexual married men and 20 to 25% of heterosexual married women will also have an extramarital affair during their lifetime. 1) The sex drive evolved to motivate individuals to seek copulation with a range of partners; 2) romantic love evolved to motivate individuals to focus their mating energy on specific partners, thereby conserving courtship time and metabolic energy; 3) partner attachment evolved to motivate mating individuals to remain together at least long enough to rear a single child through infancy together. Researchers have broadened the definition of infidelity to include sexual infidelity (sexual exchange with no romantic involvement), romantic infidelity (romantic exchanges with no sexual involvement) and sexual and romantic involvement. Myriad psychological, cultural and economic variables play a role in the frequency and expression of infidelity. In a recent survey of single American men and women, 60% of men and 53% of women admitted to “mate poaching,” trying to woo an individual away from a committed relationship to begin a relationship with them instead. Regardless of the correlation between relationship dissatisfaction and adultery, among individuals engaging in infidelity in one study, 56% of men and 34% of women rated their marriage as “happy” or “very happy,” suggesting that genetics may also play a role in philandering. Studies show the possibility of a gene that correlates to infidelity.

Human beings have three primary brain systems related to love. Infidelity doesn’t necessarily signal an unhappy relationship.

These three basic neural systems interact with one another and other brain systems in myriad flexible, combinatorial patterns to provide the range of motivations, emotions and behaviors necessary to orchestrate our complex human reproductive strategy. It was also common among the classical Greeks and Romans, pre-industrial Europeans, historical Japanese, Chinese and Hindus and among the traditional Inuit of the arctic, Kuikuru of the jungles of Brazil, Kofyar of Nigeria, Turu of Tanzania and many other tribal societies. But one thing is clear: infidelity is a worldwide phenomenon that occurs with remarkable regularity, despite near universal disapproval of this behavior. In 2008, Walum and colleagues investigated whether the various genes affect pair-bonding behavior in humans; 552 couples were examined; all had been married or co-habiting for at least five years.But this brain architecture makes it biologically possible to express deep feelings of attachment for one partner, while one feels intense romantic love for another individual, while one feels the sex drive for even more extra-dyadic partners. Men carrying the 334 vasopressin allele in a specific region of the vasopressin system scored significantly lower on the Partner Bonding Scale, indicating less feelings of attachment to their spouse.
