Beauty is universal.
Human beings are evolved to be equipped with a beauty detector. Since we can’t go around and draw people’s blood and test their DNA, we’ve evolved by natural selection an eye to detect signs of fertility.
Beauty traits are perceptual signals of how well equipped the other person’s body is to serve and share the genetic stake of our child.
If you go to any tribes, countries, or cities in the world and ask all kinds of people to come up with an ideal beauty image, chances are they’d all come up with the same characteristics.
Beauty features such as symmetry, cleanliness, long hair, straight, white teeth, round, big, clear eyes, and full lips are universal because they are signs indicating that a person has developed normality, is healthy, free of infection and deformity, carries good genes, has a strong immune system, very fertile, and capable of making the fittest offspring.
Men are attracted to women who have:
Full lips (a sign that you have a lot of estrogen - fertile),
Skinny jaw bones (lack of testosterone - fertile),
Long, luxurious hair (history of good health. Lack of nutrition and infection weakens the hair and damages the shaft),
Straight teeth and aligned jaws (a good-looking face usually has optimal alignment for chewing),
Large breasts (again, signs of fertility and good quantity of fresh breast milk),
Wide hips (signs of good, healthy fats, good calorie reserved for pregnancy),
and optimal waist-to-hip ratio (shows good youth and signs of never being pregnant).
On the other hand, women are attracted to men who have high doses of testosterone in their blood, and low levels of estrogen.
High cheek bones, lean muscle mass, strong chins and foreheads, broad shoulders, large testicles, angular jaws are all signs of a healthy fertile male with normal hormone and ideal testosterone levels.
Heterosexual men prefer women who have a lot of estrogens and very little testosterone in their blood because women with large doses of testosterone are less fertile. This is why most men find masculine-looking girls undesirable.
