Some gentle kiss of humanity, some hunger, some deep, some excitement, there is a ceremony of the kiss, there are moved, kiss, there is a Hollywood-style kiss the air upside down, and perhaps to wake Sleeping Beauty fairy tale of the millennium kiss. "Scientific American" scientists recently published a research report on the kiss, which makes a refreshing insights.
Kiss failed development not smooth
The evolution of our lips began feeding, and later applied to the speech. But kissing the function to meet our needs more. Kissing convey messages of love, the body's response and sexual implication. Research shows that if two people kissing for the first time fails, it will lead to the development of two people did not go well. Some scientists believe that the lips touch the lips and because it provoked the evolution of the human desire to find partners.
The evolutionary history of mankind has always been filled with such intense feelings of warmth and expression of movement. As early as 60 years in the 20th century, there is the British zoologist make the action of human kissing mothers feeding their children from the mouth when feeding. In the gorilla who also exists a similar action, therefore, our ancestors may also be the case. This action was slowly evolved into a way to soothe babies, especially in times of food scarcity, in a timely manner that caress and comfort. Then human beings to accept such a way to slowly evolve into the single action of a wide variety of complex kissing.
Useful chemicals
With the constant evolution of kissing, sometimes people began to feel addicted to this. The body is also the site of nerve of the most densely lips, when the kissing, the nerves feel like a rocket to send to the brain and body, the release of an extremely pleasant feeling.
Affecting the human brain of 12 to 13 types of nervous system, in a time when there are five kinds of kissing will be active again. They will be from the lips, voice, cheeks, nose, there is shuttling back and forth between the transmission of information. Of them some information after arriving in the brain, the activation of the cortex in a number of organizations, to release a control of human stress chemicals, which controls people's emotions, impulses, social bond and sexual implication. Psychologist WendyL.Hill and his assistant were compared 15 pairs of couples in the kissing around the differences. The results showed that there are two kinds of hormone levels were significantly elevated.
A recent Gallup survey shows that 58 respondents 59% of men and 122 women surveyed 66% admitted that they and the other half are often favored by the kind of good feeling would be the first After the failure of a kiss disappear. The kiss has no flaws, but let you feel wrong, resulting in two people's good sense also disappeared. This is probably the kiss of death Bar.
A barometer of relations between the two
From Darwin's point of view, the choice is through genetically inherited. For us humans, the choice of partners, usually linked to love each other. Fisher's paper in 2005 proposed a "mechanical theory of attraction", which prompted the energy of another human to take note of the energy of each other to attract the opposite sex together to complete the mission and survive.
Gallup testing has shown that women think kissing is a barometer of progress in the relationship between two people. Because for women, will afford the responsibility of nurturing the next generation, so by kissing, they can know the other half is able to feed the children with him.
But the kiss is not necessary. Many animals in the case of kissing does not occur can also be combined and reproduce. Humans did not even kiss. Denmark, Finland, the scientific community have found that some of the ethnic mix of men and women who can kiss bath, but they may regard as a great evil. In 1897 a French anthropologist Pauld'enjoy reported that at that time in China, kissing is seen as immoral.
Those who favor the left side of the first feelings of apathy
Some scientists suggested that the first preference when kissing on the left than the right bias in the relatively cold and not warm and emotional. In another statement, the view that the right side of the first preference of people out of their own left cheek, and it is precisely the right side of the human brain controls the right to control human emotions. Some, however, scientists do not quite agree with this statement emotional control, they also believe that this is a habit of mechanical movements.
No matter how these claims feign and kiss the behavior and there are still differences between pure scientific analysis. Science has not fully explain some phenomena, because it is much more complex than the scientific theory, but the romance is reluctantly being a little bit to break us.
