This seems a bit strange, there are more and more left-handed, according to sociologists, the left-hand of the left to the left is doubled in the past 100 years. The left-handedness has accounted for 1/4 of the population, and even reached 1/3 in some areas! In the United States, there is almost one of the three people, there is a left-handed, and the most recent president of the United States is the left-handed man - Ronald Roundan, George Bush, Bill Clinton. What does this mean for humans? Below is an elaboration of Genetologists, Genetics, which Russian psychologist Vladimir Levi and Research Genetic Physiology. Psychologist Vladimir Levi: Left-handed is not because they are born, but they are more free to show themselves, so people think they are more; the left-handed is not because of the factors in the gene. But because the world is the right to be right-handed, the left-hander must be more adaptable and tough, in order to go further in the career.
There are statistics show that there are more and more left-handed people in the population. What is this happening, is it a sudden change? Is it just a normal stage in the evolution of human development?
In fact, although there is more and more trends in left-handed, the "left-handed" process has not really emerged, and there will be no appearance in the future. Just because the left-handed is more free than the past, it seems that there seems to be more than the left hand. The world becomes more free, and it is now exposed from the past or not found. This is not only reflected in the issue of left-handed, "sexual left-handed" - is also the same reason to increase the increase of gay people. All this is from today we have more self-exhibition than ever, self-definition.
The power of the natural law is great. The most important thing is the genetic law, followed by molecular arrangement law and chemical law. The left-handed phenomenon not only exists in the living body, but also in a substance without life. The molecules in a body always have "left-handed", "right-handed", and the proportion between the two is fixed: "right-handed" molecules in any substance account for most It is about 4/5. The remaining 1/5 is "left-handed". The proportion of human right-hand and left-handed is 4: 1. This is the original foundation originating from the law of the natural left-handed leg, which is very mysterious, but it is obvious, not to be suspicious.
This law is not only for people, but also doing all organisms. Monkeys, birds, and fish have "left-handed", plants, bacteria, and viruses have "left-handed".
Why is there so many left-handed people in the United States? The proportion of left-handers accounted for the total population has been high. Is it that the left-hander is in a good condition? I think that the proportion of left-handed population is high and high birth rates, and free to show self-relaxed environments. How much is the US left-handed?
The transition between pure right-to-hand to pure left interpend can distinguish many different degrees of transitional characteristics. I am an example. I am a half-legged, or it can be said that two hands can be used in a smart, and the left and right hands can be written, draw, play the piano, but I am good at left short boxing, playing football likes to use the left foot. Like me, the second-handed genetic genetic genetic genetic in young age is not determined. There are a two-way tendency to have some "choice of freedom". And the right-handed social society suggests what the child chooses and imposes him. This option is fixed in the form of habits.
It is said that the left-handedness is talent. Gay love is also considered to be amornial. In fact, left-handed is not the excellent part of human beings, just a group of people with certain characteristics, reflecting some of human characteristics. However, they must be nervous, live with heart, carefully, and use the full mind to deal with life, because the world is not building their will, but the opposite is the opposite, the world is the first day of the right hand. The left-handedness must be more adaptable and tough, so they climb to the upper layer on the ladder of the undertakio is obviously higher than the right. We re-use other minorities as an example - sexual orientation, non-popular groups or some minorities, they have to survive, and have to depress and constrain their own personality. The proportion of gay and short subscribers in many areas is also very high, such as in the field of art, education, politics ... their achievements are very prominent.
For example, Jewish talents are reflected in financial, scientific, administrative management, chess, etc. Do you think this is the gene of Jewish? No, this is a result of hostile environment forced. This is the result of the anti-Jewish sport in history. It is the result of making them more efforts than other nations in many centuries, explore the results of their own survival and development. So, this national talent is naturally withered in Israel, which is in terms of anti-Semitism, so that it will eventually lose. Because in Israel, the Jews are not "left-handed" in the social group, but "right-handed".
Genetologist Weigan Gunda Yang: Any an evolutionary system is divided into two closely related sub-systems, one to maintain the evolution of evolution, and transform the evolution toward better aspects. Men and left-handers bear a tester behind. As a genetician studying "left-handed" problem, people often ask me: "Whether it is clearly understood what is left-handed? What is the meaning of left-handed?"
Unfortunately, it is also very strange, and science is still unable to answer such problems. And I personally have a few theories in this field. My first theory is a gender theory, its core - Men are gender with trial characteristics.
I created a binary system theory. What is this theory? People can be divided into men and women, human genes can be divided into common-stained chromosomes and genes, the brain is divided into two parts: the people in the society can be divided into two parts of left-handed and right-handed, all kinds, not very . This binary system of two parties is closely related to the nature. The nature of the binary system is that any continuous evolutionary system is divided into two closely related sub-systems. These two sub-systems are assumed in two aspects in the evolutionary process - maintaining the evolution of evolution and moving more Good aspect transformation. Such an system can improve its stability.
Five years ago, the famous Japanese famous female Murait bell has a new discovery. There are two diseases, one is a loss of spellings, one is disabled (lost movement ability - translation). If female is suffering from these two diseases, it is because the top part of the brain nerve is damaged, and the male is suffering from the two diseases. It can be seen that men are the vanguard of human evolution, leading to women. The brain nerves of male main controlling language and action have become part of the backbrain, and women have not yet reached this stage. The process of evolution of the control center of the habitual behavior in the human brain is from left to right, from forehead to the back. Some data indicate that women have at least 500 years in the process compared to men.
What is the left-handed and this theory? The left-hander is also a class of people with trial characteristics. They are similar to men, but they are only in the cultural level. The role of men played by men in gene development, and the role of left-handedness in culture, and ideological development. Left-legged makes a nation more active, and strives to adapt to complex difficult situation.
So I can affirm that in the environment where the ecology or psychologically discomfort is not suitable for people's survival, the proportion of left-handles in the crowd will rise in the environment where men's birth rate and mortality are raised. It may be a natural disaster that causes these adverse environments, or it may be a human or blame - racial misrgent, earthquake, war, famine, and so on. The left-handers put the new features of the easily and inherited their future generations, so that they transferred to the right-handed body, entered a nation's cultural blood.
When German scientists in African activities, they found that they were found to complete the (instinct) activities of the tool, and the right hand usage rate was 54%, while the right hand usage rate was the right hand. 84%, use the right hand, use the left brain.
Then I started to study the behavior of the monkey. The monkey crashes fruits with left forelimbs, and the door-to-door lasers and call the phone number (if you teach it) use the right forelimb. We know that the right front extremity is the left brain tag, which is reversed that the left front limbs are striped by the right brain. Like the fruit to eat such a function for a long time, the monkey uses the left forepet limbs, which is the right brain. So, the right brain is the old behavior of the supervisor, is conservative, and the left brain is exploratively, trying all new things. The right hand will save the old behavior in the future.
What is the meaning of the left-handed? Now let me explain. Newborns have the ability to crawl. The instinct is a way to fix it in the right brain, and is completed by the left hand. So the baby always uses the left hand. 15 years ago, people found that the right ear is sensitive to ideological, more abstract sounds, while left ear is sensitive to natural sounds. Eye? We take a flashing light (lightning) and a thinking picture (word) as an example. It turns out that lightning can be better captured by the left eye, while words, numbers, and portraits are more vaguely identified. Let's take a look at the smell. The sensitivity of human smell is a little bit in weakening, but women's sense of smell is still sensitive than men's sense of smell. The left nose is sensitive than the right nostrils.
The key to the asymmetry of these functions is the difference between the "brain road map" of the brain of the main control human behavior, the behavior of left-handed nature and a gender match, and the behavior of right-handed nature and another gender match . The left-handers are sub-systems that are active, similar to men; right-handed sub-systems, similar women. This means that the enormous innovation first occurs on the right side of the left-handed, and then the right side of the right handwriters. As a species is divided into female and female zero to ensure that the species acquire information from nature and effectively inherit the inheritance, human society is divided into two parts of the left-handed population and the right-handed population, making human spirit and psychology Development and advancement.
