Features such as a symmetrical face, full lips, and low waist-hip ratio, are commonly considered physically attractive when part of a female, because they are thought to indicate physical health and high fertility to a potential mate. Physical attractiveness is the perception of the physical traits of an individual human person as pleasing or beautiful. It can include various implications, such as sexual attractiveness, cuteness, and physique. Judgment of attractiveness of physical traits is partly universal to all human cultures, partly dependent on culture or society or time period, and partly a matter of individual subjective preference. Despite the existence of universally agreed upon signs of beauty in both genders, both heterosexual and homosexual men tend to place significantly higher value on physical appearance in a partner than women.[1] This can be explained by evolutionary psychology as a consequence of ancestral humans who selected partners based on secondary sexual characteristics, as well as general indicators of fitness (for example, symmetrical features) enjoying greater reproductive success as a result of higher fertility in those partners, although a male's ability to provide resources for offspring was probably signalled less by physical features.[1] Physical attractiveness can have a significant effect on how people are judged, in terms of employment or social opportunities, friendship, sexual behavior, and marriage.[2] In many cases, humans attribute positive characteristics, such as intelligence and honesty, to attractive people without consciously realizing it. Physical attractiveness is distinct from, but can include, sexual attractiveness. For example, humans often regard children and young individuals—both human and animal—as being highly attractive or "cute" for various reasons, but without sexual attraction.
