Why most humans are afraid of the dark, does it have anything to do with genes?

Matter! Tens of thousands of years ago, when human beings were still in the primitive, there were, people had no safety in the dark, and there were wild beasts everywhere, which made people very afraid, after tens of thousands of years, human beings still have this nature, just like other animals are afraid of fire, hundreds of thousands of years ago, human beings wantonly set fires, so that many animals remember this terrible species, so the genetic memory began. From generation to generation.

Because this is a natural attribute of human beings, it cannot be changed. On the surface, people who seem to have changed have only overcome their fears, but they are not not at all afraid. It is important to remember that human beings have only entered the age of civilization for a few thousand years, and before that, almost all cats were in the shade of forest trees, and their history can even be traced back to a long time before they have grown limbs.

In those times, humans were just a weak social animal, constantly facing the fate of becoming a meal for other predators. During the day, we can evade pursuit with good agility and good vision, but at night, the best thing to do is to hide quietly and keep an eye on what is going on around us.

Because our ancestors were afraid of the dark, our genes naturally yearn for light. Although monkeys later became apes and apes became Homo sapiens, most people still did not get rid of their fear of the dark. The only difference is the degree of fear of the dark and the degree of special fear of the dark.

The fear of darkness has evolved from late human civilization to the present day, and our fear of darkness still exists. It's just that it's getting a little weird, because most of us don't need to be afraid of the dark, especially when it comes to devices like light bulbs, cell phone screens, and televisions, so darkness is no longer a given.

So, if you or maybe one of your children is afraid of the dark in life, remember that this is an important life trait, it will not make you or your child become as weak as a chicken, it will only make your body more coordinated and more suitable for life.

Fear of the dark is also insecure: some people are very afraid of a person when they are in the dark, because they are insecure, and they will be afraid at this time, some people say that they are afraid of the dark, afraid of ghosts, and may not be able to see things clearly in a dark place, or they may be afraid of being alone.

Fear of the dark is a kind of fear of the unknown, which has little to do with age, everyone will be a little afraid of the dark, but if it is extremely afraid of the dark and affects normal life, it is a psychological problem.

I think it may be because although people have grown up, they are still a child at heart, so they are afraid of the dark, this is not a serious problem, and it does not mean that you are not an adult if you are afraid of the dark, you can allow yourself to be afraid of the dark.

Because I watched too many horror movies when I was a child, I always remember it when I grew up, and I always felt that there would be something in the dark, so I was inexplicably afraid of the dark.

Because I was frightened in the dark since I was a child, or because I was insecure in the environment in which I grew up, I will be afraid of the dark when I grow up.

Because the fear is deeply ingrained in the mind, it will not disappear with age, just like liking certain food, it will not dissipate easily.

Maybe it's because I had a shadow when I was a child, or because I experienced something terrible, so I was more afraid of the dark, and I didn't go out of such a shadow when I grew up.

It may be too influenced by some idealistic views, and the imagination is relatively rich. After watching a lot of ghost movies and listening to a lot of ghost stories, you will make up a lot of things in your brain.

The more you grow up, the more lonely you become, although your mind has matured, but when it's dark, you can't see anything, and it's normal to panic.

Insecure, in a dark place, unable to see others, insecure people are always prone to overthinking, afraid of ghosts or other creatures to harm themselves.

Fear of the dark is an instinctive reaction of living beings, not in terms of age. Therefore, being afraid of the dark is not a big deal, it is normal.

Because fear is something that accompanies people throughout their lives, it is not so easy to overcome, and even as we get older, fear will continue to deepen.

Most babai are mutated and vitolate.

du objects are harmful due to any

All of these organisms are the product of a long evolutionary process, and they have achieved a high degree of harmony with environmental conditions. If a genetic mutation occurs, it is possible to disrupt this harmony. Therefore, genetic mutations are often detrimental to the survival of organisms.

For example, the vast majority of human genetic diseases are caused by genetic mutations, which pose a serious threat to human health. Another example is the albino seedlings that are common in plants, which are also formed by genetic mutations. Due to the lack of chlorophyll, this seedling cannot photosynthesize to make organic matter, which eventually leads to death.

However, there are also a few genetic mutations that are advantageous. For example, mutations in plant disease resistance, drought tolerance, and microbial resistance are all conducive to the survival of organisms.

Because only highly ordered genes are meaningful to organisms, mutations are usually random and often do not form meaningful sequences, forming lesions.

It's easy to understand, for example, in the lottery, can you win the lottery by filling in a random number? A good genetic mutation is less than your chances of winning.

Because humans are fragile. Mutations are random. And humans have very few options to go.

Because one but one.

Bai kind of things develop to one

A higher degree of zhi, then under natural conditions, the attributes that this thing itself has are good and adapted to nature. If at the beginning of the formation of organisms hundreds of millions of years ago, the organisms themselves had not yet evolved to a higher level, and there were still many defects. Then it may not be possible to say that most genetic mutations are harmful to organisms.

Human development to today may have been quite perfect, so most of the genetic mutations are harmful to people, the nature is compared to a relatively unchanged mold, the primitive biology is compared to the original material, in the process of evolutionary run-in, organisms will be more and more adaptable to nature, to today it can be said that it is basically encountered by nature, so most of the changes are harmful to organisms, but nature is only relatively stable, there are changes, but not obvious in the short term. So living things still have the motivation to evolve. (This is purely a personal opinion and has no scientific basis).

If you don't feel secure, you're afraid of the dark. It's okay! It's still small!

In the dark you can't be sure of what's going on around you, so feeling insecure is an instinctive human self-preservation.

People are not necessarily afraid of the dark (sky), people are different. If it's another kind of "black", that's a different story.

It's a genetic instinct that has been passed down from time immemorial.

There is spirituality in the darkness. The six paths include the gui path, which is in the dark and at night is the time of their activity. You can take a look at the director of the metaphysical Q&A, many interesting answers.

Victoria's Secret Angels have to tan before they come to power.

That's because people in a dark environment don't know what's in the dark environment, and they always feel that there will be dangerous things that they don't know about in the dark environment, and people can see clearly what is in front of you during the day. Specific content design psychology, diseases, etc., fear of the dark is also a natural reaction.

It is necessary that the two moe are the people who live with four people again、

Afraid of the dark. Don't dare to turn off the lights when you sleep. I'm scared when it's closed.

Some people say that they are not born, big brother, what philosophical truth do you tell me, chicken soup for the soul, let me tell you the scientific reason, it's very simple, for 10,000 years, human vision at night is limited, and other predators are not so limited, those who are not afraid of the dark are dead, and those who are timid are easier to survive, and after 10,000 years of heredity, they all have this characteristic, think about the changes before and after other domesticated animals, and understand that it is completely inherited from ancestors.

Genes are closely related to human diseases, for example: lactose intolerance, the patient is affected by the lack of lactose hydrolase, lactase is a protein, its band is controlled by genes, if the gene that controls the expression of the protein is missing or mutated, it will cause the enzyme to not be expressed, so that the disease will occur.

For example, we usually listen to books and even see that some people are allergic to alcohol, that is, there is a lack of enzymes that can catalyze the decomposition of alcohol, why is there a lack of such enzymes, because the genes are not expressed alive, but the content of enzymes is small.

The vast majority of human diseases are genetically related. The dream of human beings to control their own health destiny is approaching reality with the deepening of research on gene function.

Modern medical research has proved that almost all diseases, except for injuries, are related to genes. Just as blood is divided into different blood types, normal genes in the human body are also divided into different genotypes, i.e., genopolymorphisms. Different genotypes are sensitive to environmental factors, and sensitive genotypes can cause diseases under the influence of environmental factors.

In addition, abnormal genes can directly cause diseases, and the diseases that occur in this case are hereditary.

It can be said that there are three root causes of disease:

1) Acquired mutations in genes;

2) interactions between normal genes and the environment;

3) Inherited genetic defects.

The vast majority of diseases can be found in genes**.

Genes, through their guidance on protein synthesis, determine how efficiently we absorb food, remove toxins from the body, and respond to infections.

There are more than 4,000 genetically related diseases in the first category, which are genetically acquired by the father or mother.

The second type of diseases are common diseases, such as heart disease, diabetes, many types of cancer, etc., which are the result of the interaction of multiple genes and multiple environmental factors.

Genes are chemical carriers of human genetic information that determine how similar and unsimilar we are to our predecessors. When genes are "working" properly, our bodies are able to develop and function normally. If a gene is not normal, or even a very small piece of the gene is abnormal, it can cause abnormal development, disease, and even death.

A healthy body depends on the continuous renewal of the body to ensure the normal quantity and quality of proteins, and these proteins cooperate with each other to ensure the normal performance of various functions of the body. Each protein is a product of a corresponding gene.

Genes can change, some of which do not cause changes in the quantity or quality of proteins, and some of which do. This change in a gene is called a mutation. Changes in the quantity or quality of proteins can cause abnormal body functions that can lead to disease.

This is a genetic inheritance that originated in the primitive period of human beings.

In the dark night, people's eyesight will become weaker, easy to become the object of predators, only people who are afraid of the dark, he naturally has a tendency to light, reduce the probability of being preyed, it is easier to stand up and save life, and continue life. And those who are too "brave" primitive people, of course, have a relatively less chance of being able to continue their genes. Countless generations of elimination and inheritance, fear of darkness has become part of the genetic makeup.

Therefore, people's fear of the dark comes from primitive genes, which can be said to be part of nature.

Of course, this will not happen now, but the combination of the acquired fear of the dark unknown and the innate genes will still make people afraid of the dark.

**Taiwan Science and Education Channel has a series of programs "What Are You Afraid of", one of which talks about why people are afraid of the dark.

This is actually an instinctive reaction of people, people's eyes are the main way to receive information, when people are in the dark, they can't observe the things around them through their eyes, and it is difficult to determine whether there is danger approaching them, at this time there will be a feeling of isolation, more or less fear. If the fear is high enough to a certain extent, it is also a psychological disorder.

Because the night will make people think of some horror movies, many horror movies now have dark themes, so many people are very afraid of the dark. There are also many sounds at night, such as the chirping of Zen in the trees, and the sound of the wind.

Also because there are few people at night, alone at home, of course scared, but there are some people who are not afraid, and that is very rare.

Because when people are in the dark, the brain is in a state of dormancy. In this state, the human body will be very slow. At this point, it will feel cold. The cold creates pressure inside. That's when there comes a sense of fear. How to overcome? It's just closing your eyes and thinking about the sun.

Fear of the dark is a manifestation of ignorance, a psychological experience that only idealists can have.

The world is material, and we cannot find anything other than material things.

So let's not be afraid of the dark, for night is no different from day.

Because darkness brings people a mysterious psychology and makes people fearful.

Because people are always afraid of the unknown.

Because we live in the light.

If you ask the ancient humans who lived in caves in ancient times, their answers are different, and therefore indefinite.

It varies depending on the environment in which you live.

People always think of black and dark, horror, ghosts. Connected.

Some souls cannot be located, and will scatter from the hair in the form of electrons.

Yes, everyone has it.

Studies have found that everyone has up to 300 defective genes, which are also genetic diseases. In most cases, defective genes do not cause genetic diseases because humans have 2 copies of each gene that they inherit from their parents, and the defective gene affects only one of them, and the other copy is still functioning, usually keeping people healthy.

Defective genes refer to defective and unsound genes, which are genetic diseases. In most cases, defective genes do not cause genetic diseases because humans have 2 copies of each gene that they inherit from their parents, and the defective gene affects only one of them, and the other copy is still functioning, usually keeping people healthy.

However, in most cases, the defective gene does not cause a genetic disorder because there are 2 copies of each gene that humans inherit from their parents, and the defective gene affects only one of them, and the other copy is still functioning, usually keeping people healthy.
