The evolutionary model of jealousy implies that jealousy responses between men and women evolved to aid them with the different reproductive challenges faced by the two sexes. It states that, when it comes to infidelity, men are concerned with their female partner becoming pregnant by another man and are therefore more likely to feel jealous in response to sexual infidelity cues.

Women can be certain of their maternity, which accounts for the decreased concern with sexual infidelity. They are however, threatened by the thought of having their partner direct resources and attention towards another woman and her offspring, this accounts for the increased concern with respect to emotional infidelity.
