Which theory suggests that symmetrical facial characteristics are attractive due to their indication of good health?

The evolutionary advantage view posits that symmetrical facial characteristics are deemed attractive because they may serve as indicators of an individual’s genetic fitness and overall health. From an evolutionary standpoint, traits that signal good health increase the likelihood of successful reproduction. Symmetry in facial features is often perceived as a sign of developmental stability and genetic quality. Therefore, attraction to symmetrical faces may be an adaptive trait that enhances mate selection, thereby contributing to the survival and reproductive success of individuals who favor such characteristics. This theory links physical attractiveness directly to evolutionary processes and biological signals, explaining why we might prefer symmetrical features in potential partners.
