What role does extramarital sex play from an evolutionary perspective?
What will be an ideal response?
From an evolutionary perspective, the genes that enable their bearers to produce larger numbers of offspring are more likely to survive from one generation to the next than genes that do not. A man who mates with one woman for life could produce a maximum of 6 to 12 offspring, depending on the length of time infants are breast-fed, postpartum sex taboos, and so on. If that same man occasionally has sex with a second woman (or a series of other women), he could produce 12 to 24 offspring. Men who seek out the "other woman" will produce more offspring, who in turn will produce more offspring carrying the genetic makeup that leads to extra-relationship liaisons.
