Question

Quizplus · Accepted Answer

From an evolutionary perspective, men have a natural inclination to protect and invest in their offspring, as it increases the likelihood of their genes being passed down to the next generation. In the case of sexual infidelity, the man may unknowingly invest resources in raising a child that is not genetically related to him, reducing the likelihood of his own genetic legacy being passed down. Therefore, a man may fear his partner's sexual infidelity as it poses a threat to his reproductive success. A and D may also be valid concerns, but they are not directly related to evolutionary psychology as C is. B is not usually considered a determining factor in male's concerns regarding infidelity.
