Attraction dating and partnering

Thornhill has been studying symmetry for 15 years and scanned faces and bodies into computers to determine symmetry ratios. 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. Body shape is of course important, too. 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.

The same goes for a male's testosterone. 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. Estrogen caps bone growth in a woman's lower face and chin, making them relatively small and short, as well as the brow, allowing for her eyes to appear prominent, Thornhill explained. Men's faces are shaped by testosterone, which helps develop a larger lower face and jaw and a prominent brow. 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. Research reported last month found women both smell and look more attractive to men at certain times of the month. Borrowing sweaty undershirts from a variety of men, Thornhill offered the shirts to the noses of women, asking for their impressions of the scents.

PSYCHOLOGICAL SECRETS OF ATTRACTION

Hands down, the women found the scent of a symmetrical man to be more attractive and desirable, especially if the woman was menstruating. By now you might be wondering how much of this we're consciously aware of. The rules of attraction, it turns out, seem sometimes to play out in our subconscious.

In some cases, women in Thornhill's study reported not smelling anything on a shirt, yet still said they were attracted to it. A study found women prefer the scent of men with genes somewhat similar to their own over the scent of nearly genetically identical or totally dissimilar men. These subconscious scents might be related to pheromones, chemical signals produced by the body to communicate reproductive quality. The human genome contains more than 1, olfactory genes—compared to approximately genes for photoreceptors in the eyes—so pheromones have received a lot of attention from basic research scientists as well as perfume manufacturers.

Pheromones clearly act as sexual attractants in the animal world. Older male elephants, for example, exude sexual prowess with a mix of chemicals the younger bulls can't muster. Milos Novotny of the Institute of Pheromone Research at Indiana University has shown that special molecules produced by male mice can simultaneously attract females and repel, and even anger, rival males.

Other studies have found similar responses throughout the animal kingdom. Yet many researchers are not sold on the idea that these odorless compounds play a role in human attraction. Count evolutionary biologist Jianzhi Zhang of the University of Michigan among the skeptical.

In , Zhang showed that a gene mutated 23 million years ago among primates in Africa and Asia that are considered to be human ancestors, allowing them to see color. This let the males notice that a female's bottom turned bright red when she was ready to mate. A study last year, however, suggested that human pheromones affect the sexual area of the brains of women and gay men in a similar manner.

Pheromones, like other scents, hitch a ride through the air on other particles, such as water droplets. They generally hover just 10 inches off the ground, however. So odds are slim they'll waft up to a human nose and fuel sudden passion at a nightclub. Watch any construction worker whistling at a passing woman from half a block away, and you can see how visual cues can be more powerful.

And while they enter the nose like other scents, that's where the comparison stops.

A pheromone's destination is a special organ called the volmeronasal organ, which humans now lack. From here the sexy scent travels along a neural pathway to the brain separate from other scents. After our ancestors began to see color, a gene important in the pheromone-signaling pathway suffered a deleterious mutation, making it impossible for the scent signals to reach the brain, Zhang said.

Although the classical pheromone pathway in both Old World primates and humans is dysfunctional, the mechanism for producing pheromones still works. Some scientists believe human pheromones might be influencing our decisions along the normal olfactory pathway. The rules of attraction might drive our initial decisions, for better or worse. But lasting relationships are about much more than what we see and smell. Scientifically speaking, opposites really do attract. Experts have a clear explanation for our tendency towards genetic diversity: Plus, parents with more diverse MHC genes birth offspring with better immune system.

sandtempgeri.ga This genetic diversity impulse cannot apply to gay couples where reproduction is taken out of the equation. And yet data suggests that gay and lesbian couples, too, prefer diversity in their partners. Though Boyfriend Twin may be a fun Tumblr, research shows that gay couples are actually a lot less likely to be homogamous than straight couples.

So in the end which dating impulse wins out? Our narcissistic tendencies, or the quest to diversify our gene pool?

People with active dopamine levels impulsive, curious types or high serotonin levels social, conscientious types tended to like people similar to themselves. But men with high testosterone tended to be drawn to women with high estrogen and oxytocin levels and vice versa.
