Final answer:
Natural selection helps us understand why men and women value good character in a marriage partner and why men care more about youth and women care more about control of resources.
Step-by-step explanation:
Natural selection helps us understand why men and women both value good character in a marriage partner because it is advantageous for individuals to choose mates with traits that will contribute to their offspring's survival and reproductive success. Good character traits, such as kindness and loyalty, can enhance a person's ability to maintain a stable and supportive relationship, which is beneficial for raising children.
On the other hand, men usually care more about youth in a marriage partner because it is associated with fertility and the ability to bear children. In evolutionary terms, men are more likely to be attracted to younger women because it increases their chances of producing offspring.
Women, on the other hand, value control of resources in a marriage partner because it ensures their and their children's well-being. Access to resources, such as food, shelter, and protection, increases the chances of survival and reproductive success for both the woman and her offspring. Therefore, women are more likely to be attracted to men who display the ability to provide and protect.
