Humans are dependent on parental help for a large portion of their lifespans compared to other mammals. Love has therefore been seen as a mechanism to promote parental support of children for this extended time period. Furthermore, researchers as early as Charles Darwin himself identified unique features of human love compared to other mammals and credit love as a major factor for creating social support systems that enabled the development and expansion of the human species. This would favor monogamous relationships over polygamy.
After all this and more, the rules of attraction for the human species are still not clearly understood. How it all factors into true love is even more mysterious. But a short list of scientific rules for the game of love is emerging.
Some are as clearly defined as the prominent, feminine eyes of a supermodel or the desirable hips of a well-built man. Other rules work at the subconscious level, motivating us to action for evolutionary reasons that are tucked inside clouds of infatuation. In the end, lasting love depends at least as much on behavior as biology.
Symmetry equals sex Starting at conception, the human body develops by neatly splitting cells. If every division were to go perfectly, the result would be a baby whose left and right sides are mirror images.
Genetic mutations and environmental pressures skew symmetryand the results have lifelong implications. Good symmetry shows that an individual has the genetic goods to survive development, is healthy, and is a good and fertile choice for mating.
Both men and women rated symmetrical members of the opposite sex as more attractive and in better health than their less symmetrical counterparts. The differences can be just a few percent—perceivable though not necessarily noticeable.
By questioning the study participants, Thornhill also found that men with higher degrees of symmetry enjoy more sexual partners than men of lower symmetry. They are being sexually competed for. They have to be wooed and all that.
And scientists have some numbers to prove it. Women with a WHR of 0. And an analysis of hourglass figures of Playboy models and Miss America contestants showed that the majority of these women boast a WHR of 0. In general, a range of 0. What exactly is encoded in the hip ratio? A big fat clue to whether the person will have enough energy to care for offspring.
Where fat is deposited on the body is determined by sex hormones; testosterone in men and estrogen in women. If a woman produces the proper amount and mixture of estrogen, then her WHR will naturally fall into the desired range. People in the ideal hip-ratio range, regardless of weight, are less susceptible to disease such as cardiovascular disorders, cancer, and diabetes, studies have shown.
Women in this range also have less difficulty conceiving. Men and women possessing these traits are seen as attractive, Thornhill said, because they advertise reproductive health.
Another recent study revealed that symmetrical dancers are seen as more attractive. Sniff this Research reported last month found women both smell and look more attractive to men at certain times of the month.
And symmetrical men smell better. Borrowing sweaty undershirts from a variety of men, Thornhill offered the shirts to the noses of women, asking for their impressions of the scents. Hands down, the women found the scent of a symmetrical man to be more attractive and desirable, especially if the woman was menstruating.Complex CSP for Chemistry Reduction and Analysis TIANFENG LU, YIGUANG JU, and CHUNG K.
