Despite previous studies (done as early as 1997) on sexual dimorphism showing feminine preferences in female faces and mixed findings in male faces. A 2014 study on preferences for sexual dimorphism on attractiveness levels in male faces found both male and female participants preferred masculine faces to androgynous faces in high attractiveness, but mixed results in low attractiveness.<ref>https://www.sciencedirect.com/science/article/abs/pii/S0191886914007132</ref> | Despite previous studies (done as early as 1997) on sexual dimorphism showing feminine preferences in female faces and mixed findings in male faces.

There is considerable evidence that human sexual orientation is genetically influenced, so it is not known how homosexuality, which tends to lower [[reproductive success]], is maintained in the population at a relatively high frequency. One hypothesis proposes that while genes predisposing to homosexuality reduce homosexuals' reproductive success, they may confer some advantage in heterosexuals who carry them. However, it is not clear what such an advantage may be. | There is considerable evidence that human sexual orientation is genetically influenced, so it is not known how homosexuality, which tends to lower [[reproductive success]], is maintained in the population at a relatively high frequency.
