Men are predicted to place more value on "good looks" than will women. What are some of the possible adaptive values of this male preference?

(Answers will vary.) Female attractiveness may be an indicator of genetic quality and/or fertility. Feminine features favored by men in Western cultures are associated with strong immune systems, good health, high estrogen levels, and fertility. Fertility varies considerably due to age, health, and body weight. For instance, women who are younger have higher fecundity, and women with a particular body shape (narrow waist and large breasts) have higher levels of estradiol and are three times more likely to conceive a child than other women. However, cultural influences also play a role in shaping definitions of attractiveness, which can complement or counteract selection.
