In the article “The Biological Purpose of Beauty” by Michael Sones he writes, “The biological purpose of beauty is to attract for purposes of sex. The biological purpose of sex is not fun but reproduction.” He also writes, “Beauty attracts. Youth and health in humans are attractive because they signify reproductive capacity.” Geoffrey Cowley’s article “The Biology of Beauty” supports this theory. He writes, “Studies have established that people everywhere-regardless of race, class or age-share a sense of what’s attractive.” According to the article, “One key to physical attractiveness is symmetry; humans, like other species, show a strong preference for individuals whose right and left sides are well matched.” This proves that everyone is born with a sense of what is attractive, proving that beauty is biological. Geoffrey Cowley also writes about a biologist Randy Thornhill who had researched the daily struggles of scorpion flies. Through research Thornhill discovered that the female scorpion flies preferred symmetrical males which brought his attent

ion to humans. Along with psychologist Steven Gangestad, Thornhill measured the body symmetry of college-age mean and women. According to Geoffrey Cowley, “By adding up right-left disparities in seven measurements-the breadth of feet, ankles, hands, wrists and elbows, as well as the breadth and length of the ears-the researchers scored each subjects overall body asymmetry.” The researchers also had each participant fill out a very personal questionnaire. Cowley writes, “In a 1994 study, they found that the most symmetrical males had started having sex three to four years earlier than their most lopsided brethren. For both men and women, greater symmetry predicted a larger number of past sex partners.” This proves that symmetry is seen as beauty and that it does attract for purposes of sex. The biological theory of sex is that sex is for reproduction purposes. University of Michigan researchers also found that health is associated to facial symmetry. They had 100 students keep a diary over a two month time period. They concluded that the least symmetrical people had the most physical and emotional complaints. This again relates to beauty being biological. The biological theory of this is that humans find symmetrical faces more attractive because they give the impression that the person is healthy. Cowley also writes about psychologist Victor Johnston, who through research has proved that the faces found most attractive are extreme. Cowley writes, “As a rule, he finds that an ideal female has a higher forehead than an average one, as well as fuller lips, a shorter jaw and a smaller chin and nose.” According to an article called “Isn’t She Lovely?” by Brad Lemley, Johnston says, “In females
