Which blood group is the oldest? Which human blood type and Rh factor are the rarest in the world?
Since school, we have been taught that human blood is conventionally divided into four large groups, each of which, in turn, is divided depending on the positive or negative Rh factor.
The fourth negative blood group is the least common (in international terminology it is called AB RH-). This type was recorded in only 0.4% of all people who had blood tests. Today you can find out all the information you need about the rarest blood group.
Why is AB RH blood less common than others?
The difference between different types of blood is due to the presence of some specific proteins on red blood cells. They are called “blood group antigens.” There are many specific antigens in red blood cells, for which many classifications of blood groups have been invented. There are 32 types of them in the human body. However, we can conditionally divide all blood into only 4 groups.
Question about blood groups
The most important indicator in this matter is the location of the main groups of antigen proteins (AB0) and Rh. The presence of A and B antigens in red blood cells determines which of the four main groups the blood of a particular individual belongs to. By the way, the blood type is finally formed in the child’s body by about 16-18 months of his life, so the test can be taken only after the patient reaches two years of age.Main blood groups:
- Group 0 (first) – absence of antigens in plasma cells;
- Group A (second) – has antigen A;
- Group B (third) – has antigen B;
- Group AB (fourth) – has both antigens A and B.
The simultaneous presence of both antigen proteins (A and B) is a natural phenomenon, which indicates that some organisms were able to perfectly adapt to external conditions. The fourth blood group does not have antibodies, so blood of any other group can be transfused into it - this is the phenomenon of adaptation. But, unfortunately, a small number of people have AB blood.
Question about Rh factor
In addition to antigens A and B, antigen D also determines its value in the human body. If a patient has this type of antigen in his blood, then his Rh factor will be positive (Rh +). In contrast, people with Rh-negative blood types do not have this antigen (Rh-). 85% of all inhabitants of the globe have blood with antigen D, that is, positive in the Rh plan. Its presence or absence does not depend in any way on antigens A and B, and therefore any of the four blood groups has either Rh+ or Rh -.But since the fourth group itself is rare (only 1% of people among all the inhabitants of our planet flow in the veins), then taking into account the Rh negative factor, this figure becomes even smaller (as we have already said, approximately 0.4%). Now you know why AB RH- blood is considered the rarest.
Characteristics of people with rare blood types
Research shows that AB RH- speakers have good organizational skills. But there is a big but! If they are in a depressed mood, it is very difficult for them to make good decisions. People with the fourth blood group are mysterious, they have a unique charisma. This applies to both appearance and character.Very rarely such individuals have health problems. Much, of course, depends on the circumstances, lifestyle, and most importantly, on the mood in which they are. However, in friendship, love, marriage, people with this rare blood type are selfless and almost ideal: they are happy and contented only if their partner also feels good.
What they do in life is important for representatives of the 4th blood group. It is their favorite profession that most influences the strengthening or weakening of their body.
Health
- People with blood type AB RH- are very strong physically. Their metabolism works great.
- Carriers of this blood type should eat a mixed diet. They can eat meat, but only in small quantities and not too fatty varieties. A strong digestive system allows you to tolerate all dairy products well. People with blood type IV love to eat fish.
- In matters of sports, swimming is recommended for such individuals.
- In addition to water sports, they are also suitable for cycling, hiking and walking.
BLOOD TYPE
Blood type is your serial number
Our past, present and future depend on our blood type! Each blood group has a special characteristic...
Our past, present and future depend on our blood type! Each blood group has a special type of immunity peculiar to it, which determines the vital resources of a person laid down by nature. By determining our blood type, we can use our potential given to us from birth. Blood type is the path measured out for us by fate, the main condition of which is to follow a given trajectory. By harmonizing your capabilities and boundaries, you can literally influence the formation of a prosperous destiny.
There are four blood groups, with differing biochemical characteristics. This fact was established by science at the beginning of the twentieth century. Throughout the world, four blood groups are designated by symbols: I(0), II(A), III(B), IV(AB).
Blood type 0(I) is the most common on the planet - it flows in the veins of 45% of humanity. 
The first blood group I(0) is the oldest. She is called the first because she was the first to appear on earth.
It is not for nothing that those with the first blood group are the bearers of leadership qualities and are endowed with excellent health and irrepressible energy.
A(II) blood type predominates among Europeans - approximately 35% of people are its carriers. 
New living conditions led to a genetic mutation of the blood - a person appeared with new character qualities, a person with blood group II (A)
B(III) blood group is less numerous - it can be found in only 13% of us. 
A new blood mutation gave birth to people with a new III (B) blood group, whose immune system accepted exactly this way of life.
AB(IV) blood type is the rarest on Earth, found in only 7% of people. 
At the turn of the new era, during the campaigns of conquest, a mixing of peoples and a merging of blood occurred, which led to the appearance of a person with IV (AB) blood group. 
The difference between one group and another is determined by the characteristics of blood proteins. Several systems have been created to classify these fairly numerous proteins. The most famous of them is the AB0 system (read - a, 6, zero), in which four groups are distinguished - I, II, III, IV.
Group I is called zero and is designated 00, which indicates the presence of two identical genes that determine the group trait - one zero received from the father, the other from the mother.
If a child is diagnosed with blood group I, this means that both the father and mother necessarily have gene 0, but this does not mean at all that they also have group I, since their second genes could be different.
The group II gene is designated by the letter A. And if a child receives such a gene from both parents, then he, of course, will have blood group II (AA). But he will have the same group even if he receives gene 0 from one of his parents and gene A from the other, since gene 0 has one feature - it cannot express itself in the presence of gene A.
The gene for blood group III is designated by the letter B. This group is also formed in those who received from their parents two identical BB genes or two different ones - B and 0, because in this combination the 0 gene does not manifest itself.
What will happen if a child inherits gene A from one of the parents, and gene B from the other? They are tolerant of each other, one does not suppress the other, and their combination leads to the appearance of a new trait - blood group IV (AB).
Choosing a partner based on blood type
Japanese scientist Masahito Naomi, in his book “You are what your blood type is,” argues that blood type also affects a person’s character and abilities.
For example, he states:
“If you have blood type 1, it means that at heart you are a leader and an enthusiast.
Second, you will pay attention to detail, be hardworking and diligent.
Third, expect creativity and non-standard behavior.
The fourth is a good organizer with imaginative thinking.”
And today Japan is gripped by the excitement of blood type selection, starting in kindergarten and ending with sports teams. Scientists have found that people with different blood groups are predisposed to different diseases.
Large corporations such as Nissan, Toyota or Hitachi ask you to indicate your blood type in the application form. And not in order to make everyone donors, but they suggest using the employee’s personal characteristics as best as possible.
Japanese experts concluded that blood groups even influence a person’s character.
Jeanne Louis Degadenzi will help you determine by your blood type what kind of partner you are in love.
In laboratories, from a drop of blood you can find out what a person ate for lunch, establish paternity, and signs of various diseases.
But to “discern” talent, character, mood - this is unlikely. And there is no leisure to do this, there is no money.
Let's look at some characteristics of different blood groups.
Group - First.
Leader, strong, self-confident. If you set a goal for yourself, you will fight for it until you achieve it. Know how to choose the direction to move forward. Believe in yourself and are not devoid of emotion. You are self-confident, strong and assertive, and you can give everything to achieve your goal. However, you have problems: narcissism and arrogance can hinder you.
You also have weaknesses: you are very jealous and fussy, and, in addition, you are painfully ambitious and have difficulty withstanding even fair criticism.
Speakers of the first group are the most purposeful. They are always striving for power and becoming informal leaders. The motto of the first blood group is: “Fight and search, find and not give up.”
People of this type are not devoid of emotionality and self-confidence.
Weaknesses: poor adaptation to new nutritional and environmental conditions. The immune system can become overactive and attack its own body.
Stomach ulcer
Inflammatory diseases - arthritis, colitis,
· Duodenal ulcer, gastritis, severe forms of gastrointestinal tract diseases,
· Infants develop purulent-septic infections more often,
Bleeding disorders
· Thyroid dysfunction,
· Allergic disorders.
Sexual traits:
Man. In love games - he is a talent! What he loves most about a woman is when she makes him wait. But when he finally gets his way, his chosen one will not be disappointed: he is the most wonderful lover.
Woman. She needs a man who can hold her tightly in his arms! Attractive and jealous, she cannot stand it when her companion casts even fleeting glances at a random passerby. Her greed for sex will lead to exhaustion, and perhaps will greatly please her partner.
Intense physical exercises are indicated: aerobics, martial arts, contact sports, running.
Group - Second.
Sedentary, sociable, adherent of law and order, honest, loyal. Good adaptation to new nutritional and environmental conditions.
You love harmony, calm and order. You work well with other people. In addition, they are sensitive, patient and friendly. You have a heightened sense of duty and justice. Your weaknesses include stubbornness and an inability to relax, being self-absorbed.
The weak point of this group may be a penchant for alcoholic drinks and rich food.
People with the second blood group feel great in subordinate positions, the main thing is that there are like-minded people nearby. They love comfort, spiritual and everyday, and hate conflicts. They are romantics at heart, but sometimes they can be stubborn and irritable.
What diseases are you predisposed to?
· Rheumatic diseases,
Type 1 diabetes
· Cardiac ischemia,
· Bronchial asthma,
· Allergies,
· Leukemia,
· Cholecystitis,
· Cholelithiasis,
· Cancer.
Sexual traits:
Man. He is very shy, expresses his love with a glance, a light touch of the hand, but if he decides to reveal himself, he does it quite sharply. In family life, the partner must constantly prove that she loves him. He loves to feel maternal care, so he often chooses women older than himself.
Woman. She is shy, and also suspicious - even when she falls in love, she will never show it to the first one. But if the relationship is determined, she is an excellent wife: loving, devoted. And she can soon become very sensual.
The physical activity regimen should ensure calm and concentration: hatha yoga, tai chi chuan.
Third blood group.
Open, optimistic, with a thirst for adventure, most of them are ascetics and philosophers. The third blood group is distinguished by individualism. People in this group always do as they see fit. You are a mature individualist.
However, they have poor contact with other groups, are taciturn, and often suffer from depression.
You adapt to everything easily, are flexible, and do not suffer from a lack of imagination. However, the desire to be independent can sometimes be unnecessary and turn into weakness.
What diseases are you predisposed to?
· Pneumonia,
Development of infections after surgery,
· In women - purulent mastitis, sepsis after childbirth,
Radiculitis, osteochondrosis, joint diseases,
Chronic fatigue syndrome
· Autoimmune disorders,
· Multiple, multiple sclerosis.
Sexual traits:
Man. Everyone takes him for a Don Juan, although he himself knows very well that this is not so. He is a lover of seduction, but only because he is afraid of love! He will be a good husband, who will be unfaithful from time to time, but you can always rely on him.
Woman. She hides fidelity behind some extravagance, but she will be a faithful wife. In love, she needs to take the initiative into her own hands if her chosen one has a third blood type. Yes, sex is far from the most important thing for him. She will have to turn into some kind of vampire - and literally suck his sexuality out of him!
Moderate physical activity combined with mental balancing: cycling, tennis, swimming.
The fourth blood group is perhaps the most balanced.
People with blood type IV are easy to get along with. She is distinguished by gentleness and goodwill. They are benevolent and calm. People with any other blood type will feel great around these people. They know how to entertain, are tactful and honest at the same time.
A significant drawback is that they are extremely indecisive, cannot make decisions and are afraid of everything new. Weakness in constant internal conflicts, sometimes reducing self-esteem.
What diseases are you predisposed to?
ARVI, influenza and other infections,
· Sore throat, sinusitis,
· Heart diseases,
· Cancer,
· Anemia.
Sexual traits:
Man. He has a great ability to charm women, he loves their company very much. His feelings are shallow, and he can make love almost constantly.
And woe to the one who tells him: “Not today, dear!” - She won't see him again.
Woman. She is also able to attract the attention of a man, but at the same time she is strict and demanding. As soon as she allows someone to “take her by the reins,” she will feel an indefinable desire to live on the condition that she will be given as much attention as she wants. She will overwhelm her lover so much that, rest assured, he will not sit at home for long.
Calming physical activity: yoga, tai chi chuan. All this in combination with moderate physical activity: walking, cycling, tennis.
The defining component of blood is the Rh factor or antigen. It is located on the surface of red blood cells (erythrocytes). More than 85 percent of the population have this Rh factor and are classified as Rh positive.
Those people who do not have it are considered Rh negative. The present and future of a person depends on his blood type. Each group has its own type of immunity, which to a certain extent determines a person’s life resource.
How to find out your blood type
So, there are four blood groups in total, each of which differs in certain biochemical characteristics. This fact has been established by science a long time ago - around the beginning of the twentieth century.
Throughout the world, these groups are designated by the following symbols: I(0), II(A), III(B), IV(AB). The first is the most common throughout the world, since approximately 45 percent of the inhabitants of our planet have it.
The blood of the second group belongs to the majority of European residents, and almost 35 percent of the population have it. The third group is not very numerous, since it is found in only 13 percent of the world's population.
Well, the fourth blood group is the rarest, because only 7 percent of the planet’s population are its carriers. And if owners of the first blood group with a negative Rh factor are quite common, then Rh-negative owners of the fourth blood group are very rare.
Donate blood for donation
It is worth saying that positive blood can be transfused with negative blood, but the opposite should not be done under any circumstances.
The first blood group can be transfused to any group, but it is important to remember that under no circumstances should blood of another group be transfused to it - only the first.
Blood of the second group is suitable for the second and fourth, but for her only the first or second.
The third blood group can be transfused to the third or fourth, but the first or third is suitable for it.
The fourth blood group, the rarest, is allowed to be transfused only to people who have a similar blood type, but for the fourth, any blood type is suitable.
Most common blood type
The most common first blood group
This group is the oldest, which appeared a long time ago. Those with the first blood group usually have a predisposition to allergies, arthritis, decreased thyroid function, and also a tendency to blood clotting disorders. In addition, such people often suffer from stomach ulcers and other diseases directly related to the gastrointestinal tract.
As for personal characteristics, those with the first blood group are, as a rule, leaders in life. They are quite successful in sports and are often workaholics. These are very purposeful people who always try to achieve their goals.
The rarest blood type
The rarest blood type is fourth negative. The fourth positive is much more common. The fourth group is generally a mystery, because it appeared as a result of the merger of two completely different types - A and B.
This is a young group, and people who have it have a flexible immune system. This group is unique in that it appeared not due to the influence of the external environment, but as a result of mixed marriages. It is worth saying that this group is the most biologically complex.
Antigens sometimes make it similar to the second, and sometimes even to the third. Sometimes it also happens that this rare group is something of a combination of both of these groups.
It is believed that the fourth blood group appeared later than all the others - about a thousand years ago as a result of the mixing of Mongoloids and Indo-Europeans. There is also another version of the so-called “bohemian” blood group, which says that after a person was able to simply provide shelter and food for himself, he was “drawn to the beautiful” and he had a desire to express himself in creativity.
Indeed, representatives of the fourth blood group are considered the most creative individuals. The lives of such people are dominated by fantasies, emotions, love of beauty and intuition. They have a rich mental organization, a subtle perception of reality and impeccable taste.
The positive qualities of such people are kindness, compassion, selflessness and altruism. Such a person will always listen, reassure and sympathize. But at the same time, the sensitivity of such people can be considered their disadvantage.
Due to the fact that those with the fourth blood group take everything too seriously, they sometimes get carried away. These people often go to extremes. They, as a rule, act under the influence of feelings that are so intense that the mind is simply unable to curb them.
By the way, there are many fanatics among such people. But even if it doesn’t come to the point of fanaticism, the owners of the fourth group most often look like people slightly “not of this world.” They are impractical, absent-minded, often completely unsuited to solving everyday problems, and they are also very touchy about all this.
The craving for beauty in those with the fourth blood group can also manifest itself in different ways: from the creation of works of art in the most developed representatives, to psychological dependence on romance, sex and pleasure in the more primitive ones, which sometimes leads them to a vicious lifestyle.
It cannot be said that those with the 4th blood group are quite multifaceted and spiritual. They often rush from one extreme to another, and can be both harsh and indecisive. Such people can often be seen in lists of the most talented and remarkable personalities.
In general, despite many advantages, owners of the fourth blood group would still benefit from some qualities that are characteristic of people with the first blood group - discipline and fortitude, for example. But even if the named character traits were not inherited by a person from birth, he may well develop them throughout his life, because habit, as they say, is a second character.
Such a phrase as blood type began to be used only in the twentieth century. This discovery was made by the Austrian physician, chemist and immunologist K. Landsteiner. He made a great discovery - he discovered three - A, B, 0. And a couple of years later, Karl's students discovered the existence of another group - the fourth, which is considered the rarest blood group at present - AB.
Blood is a special type of liquid connective tissue. It consists of cells - formed elements located far from each other and an intercellular substance called plasma.
Its other name is zero, which dates back to the most ancient times. It is believed that she appeared the very first. About 50,000 years ago, 100% of the planet's population were carriers of this blood type. They consisted exclusively of the meat they obtained. That is, these people are hunters, people are predators.
After about 10 thousand years, people, in search of new lands for hunting, moved to new places. But these places turned out to be poorer, there was not enough food and they had to look for new sources of food. To feed his tribe, man began to develop the land, grow edible plants and prepare food from them. Thus, A was formed. It is believed that it originated in the Middle East and Asia, it has stronger immunity, and it rapidly spread to the territory of Future Europe.
After another 10 thousand years, V was born. This group belonged to nomadic herders who lived in a harsh climate and had a monotonous diet. The diet of this group contained only fermented milk products. Nomads spent a lot of time on the road, overcoming hunger and the vagaries of nature. Only the most resilient, with the strongest immunity, survived.
Scientists consider the fourth blood group, AB, to be the youngest and rarest blood group. The uniqueness of this is that it retained the features of both the second and third groups.
It is assumed that it appeared when people with the second blood group from Central and Eastern Europe began to create families with the third blood group from Asia.
Today, only 5% of people are carriers of the AB blood group. These are people with a positive Rh factor. The number of people with the rarest blood group and negative Rh factor is only 0.3%.
is a special protein located in the membranes of red blood cells. Those who have the protein present are Rh positive. Those who lack it are Rh negative.
AB blood is rightly considered to be the rarest blood group in the world. It is inherited by the future child from his parents. The fourth blood group is inherited in 50%, provided that both parents have the fourth blood group, in 25% of parents with the third and fourth, second and fourth, and second and third blood groups. It turns out that out of ten options, only four can give the rarest blood type. Despite the fact that you can get the second and third in seven cases out of ten.
The presence of antigens A and B indicates that organisms have adapted and developed a certain resistance to environmental influences.
The fourth group is a universal recipient, that is, but the fourth group itself is suitable only for itself. The first blood group, on the contrary, is a universal donor; it can be transfused to any other groups, but only the first is suitable for the first one. So, after all, what is the rarest blood group today, first or fourth, if they are so oppositely similar?
As mentioned above, it appeared more than 50,000 years ago - it is the very first group that appeared on the planet and therefore cannot be the rarest.
Possible diseases
Scientists have discovered. Those born with the fourth group are prone to heart disease, problems with blood vessels and the digestive tract. This does not mean that the disease will definitely occur, but only about its possibility. But there is an opinion that the fourth group is the least susceptible to allergic reactions and problems with the immune system.
Personal qualities
Among psychologists there is also an opinion about the relationship. The Japanese have long learned to determine a person’s temperament by blood type. Some companies select candidates based on blood types.
Proponents of such theories are of the opinion that people with the rare fourth blood group have a gentle character. They are not conflicting and always make compromises. These are very versatile and talented individuals with a delicate taste and wild imagination.
They make good scientists, musicians, artists, artists.
It is believed that the rarest blood group in Russia occurs in 7-10%. Thus, Russia has the largest number of people with the fourth blood group.
There are many classifications that divide blood into groups. All are designed to target different antigens and antibodies—small particles that are either attached to the red blood cell membrane or float freely in the plasma.
The first experiments with blood transfusion most often ended in the death of the patient. The thing is that then people did not have the slightest idea about blood groups. Today, the most common classifications are the AB0 system and the Rh factor system.
According to the ABO system, blood is classified as follows:
- 0 – first,
- A - second,
- B - third,
- AB is the fourth.
What determines the rarity of a blood group?
The rarity of blood groups, like many other features of our body, depends on natural selection. The fact is that throughout the entire two-million-year history of mankind, people have had to adapt to new conditions of existence.
The climate changed, new diseases appeared, and our blood developed with them. The oldest and most common group is the first. Scientists believe that it was she who was the original, and all the groups known today came from her.
Rare groups appeared much later, so they are not so common in the population.
Which group is the least common?
In the world, the leader in rarity is 4 negative blood group. Despite popular belief, 4 positive is approximately 3 times more common. There are more people with it than people with negative blood type 3.
Why is group 4 the least common?
The fact is that its very appearance can be considered a peculiar phenomenon. It combines the properties of two opposing blood types - A and B.
People with blood type 4 have a strong immune system that easily adapts to environmental conditions. By biological standards, this group is the most complex.
This type of blood appeared only a couple of thousand years ago. At the moment, it is the most in demand at any blood transfusion station, since there are still not many carriers of it.
The youngest and rarest group is the fourth
What blood is most common?
The most common blood is the first group (or zero according to the AB0 classification). The second is a little less common.
The third and fourth are considered rare. The total percentage of their carriers in the world does not exceed 13–15.
The most common types (1 and 2) arose at the dawn of mankind. Their carriers are considered the most susceptible to allergies of various origins, autoimmune processes and other diseases. Blood of this type has changed little over hundreds of thousands of years, so it is considered the least adapted to modern conditions.
The percentage of blood types is also determined by the Rh factor. Positive is much more common than negative. Even 1 negative group, which is the leader among negative blood types, occurs in 7% of people.
The distribution of blood groups also depends on race. A person of the Mongoloid race will have Rh positive blood in 99% of cases, while for Europeans, Rh positive is about 85%.
Europeans are the most common carriers of group 1, Africans are carriers of group 2, and group 3 is the most common among Asians.
Blood types: percentage prevalence
As statistics show, different types of blood vary greatly in prevalence in the world. People with type 0 can be found without much difficulty, and type AB blood is unique in its own way.
The following table will help you finally understand which groups are the most common and which are much less common:
| 0+ | 40% |
| 0- | 7% |
| A+ | 34% |
| A- | 6% |
| B+ | 8% |
| IN- | 1% |
| AB+ | 3% |
| AB- | 1% |
Who should donate blood?
Medical sources say that it is always preferable to transfuse a person with blood of the exact group of which he is a carrier. Therefore, it is very important that blood banks have all types of blood.
The main rule of blood transfusion is that people with positive blood can be given negative blood. If done the other way around, the person who needs the transfusion will die. This is due to the biological characteristics of the antigen-antibody system.
Although type 1 is considered rare, its uniqueness lies in the fact that in emergency cases such people can be transfused with blood of any type, provided that the Rh factors are compatible. At the same time, other types of blood are not so universal.
Group AB can only be transfused to people with the same blood type.
No matter what kind of blood you have, by donating it you will help save a person’s life. The most expensive and sought after blood is Rh negative. If you are one of the 15% of people who carry it, be sure to think about the possibility of becoming a donor. Periodic blood donation is not only charity, but also a way to improve the functional state of your hematopoietic system.
