Final answer:
Evolutionary psychologists suggest that males are sexually assertive while females are more selective of sexual partners due to sexual selection and sexual dimorphism. Males often display elaborate ornaments or behaviors to attract mates, while females are more selective in choosing the most desirable mates. This is because males typically have more variance in reproductive success, leading to a strong selection pressure for them to compete and attract mates.
Step-by-step explanation:
Evolutionary psychologists suggest that males are sexually assertive while females are more selective of sexual partners because of sexual selection and sexual dimorphism. In many species, males display elaborate ornaments or behaviors to attract mates, while females are more selective in choosing the most desirable mates. This is because males often have more variance in reproductive success, leading to a strong selection pressure for them to compete and attract mates, while females tend to have fewer but more selected matings.
