This hypothesis suggests that secondary sexual characteristics such as a low waist-to-chest ratio or masculine facial features (e.g. strong jawline, larger brow ridge, more muscular) are reliable indicators of mate quality as the hormones that cause their development (i.e. testosterone) suppress the immune system of an individual. With immunosuppression a male would be more susceptible to diseases or pathogens. However if a male is in good enough condition to weather these negative effects, it would be indicative to women, who selected these men as mates, that they have good genes.
Males with the ability and willingness to provide resources are highly desirable to females. In our evolutionary past, this would have been demonstrated through the ability to provide food, shelter, and protection. In modern day humans, cues to high resource acquisition are presented in different ways. Cross-culturally, females show an increased preference for economic resources than do males, and those males who marry at a certain age tend to earn significantly more than males of the same age who do not marry. As females often choose mates young, the amount of resources that they actually possess may be small. Therefore, females seek traits indicative of potential resource acquisition ability such as a good education, ambition, and career potential. If a male becomes unemployed or lazy, the female is far more likely to discontinue the relationship with them.[19] In fact, even clothing can act as a cue for sexual selection, with females being more willing to engage in relationships with men wearing high status clothing
