The symmetry is indicative of your health
|
Those who were lucky to have symmetrical face probably already noticed that enjoyed success the opposite sex. Now, they say it may also reflect on their good health. The fact that a person with ideal proportions as a sign of that the body's powers are prepared to fight infections. Asthma and influenza with a high probability back to the people who have left the party exactly similar to the right.
All of this is due to the effects of testosterone and estrogen in the development, say researchers with the results of the work published in the journal "Evolution and human behavior". Symmetry probably stems the fact that some men are more courageous, and some women are more womanlike. As the study shows, they say that the man is a product of a large number of genes.
Researchers working at the University of New Mexico in the USA measured the proportion of the approximately 400 young people and compared the data with their medical card in the past three years. Measurements were parameters such as length of the chin, width of the jaw, lip width, eye width, the height of the eyes.
Subsequent studies in the UK have led to similar conclusions. Dr. Nick Neve, an evolutionary psychologist Northbridge University, explains: "We carried out a study of symmetry and concluded very skewed person turn people. And if a man or a woman of symmetrical face, it is exciting factor. you go to the man at a subconscious level, because in the evolution of people tried to reproduce in tandem with the those perceived to be more healthy individuals. Healthy genes mean a symmetrical face".
When American researchers studied the incidence and antibiotic use, we found a direct relationship of these parameters of appearance. "The study referred to in this article, we provide evidence that men is a sign of a high degree of resistance to infectious diseases, especially respiratory infections" - write the authors of this paper.
It is well known that testosterone levels linked to the ability of the infection to cope with the disease. Professor Dave Perett of the University of St. Andrew (St Andrews) also suggested that women prefer symmetrical person because it indicates healthy genes partner.
Similarly, the female lines for women is a sign of resistance to respiratory diseases. Scientists the University of New Mexico warned that women whose partners have ears, at a different level, length fingers or knees, dream up more about sex with other men during the period of ovulation.
However, researchers out that the relationship between appearance and health can be transformed years. And in the long term, excess testosterone is not always a good thing. "Testosterone affects the life, as indicated by comparative longevity castrate men," say scientists.
