The truth is, looks matter. Studies and experience prove that one s physical beauty affects friendships, marriage, and employment. Our norms of beauty may be a way to pick good breeders. According to Geoffrey Cowley of Newsweek, penguins do not choose their mates randomly females look for chubbier males who have enough fat to spend several weeks sitting on newly laid eggs. Likewise, humans search for particular characteristics in their mates.
Studies show humans are attracted to health, cleanliness, and symmetry.
Psychologist Steven Gangestad and biologist Randy Thronhill studied symmetry of college students using various measurements. They had students fill out questionnaires covering everything from temperament to sexual behavior. The most symmetrical males started having sex three to four years earlier than their lopsided counterparts. Thus, men and women with greater symmetry have a greater number of sex partners. A study of 86 couples found that women with highly symmetrical partners are more than two times as likely to climax during intercourse.
