If you suddenly find yourself in Japan, and your casual acquaintance suddenly decides to ask you an unusual question: “What is your blood type?”, Then do not rush to think that you can be offered to become a blood donor. In Japan, they are convinced that blood can determine a person's character, as well as his individual characteristics. Most Japanese people choose friends and spouses, taking into account the individual characteristics of blood, and HR managers decide on hiring. In Japan and the USA, there are several organizations that help people even make certain decisions, using individual information about the properties of the client's blood. How justified can the use of information about the blood group be and does such an original way of determining the character have any practical benefit?
How did the blood types come about?
And yet, how exactly is a blood type able to influence a person's character? In this matter, scientists tend to adhere to the officially recognized theory of evolution by Charles Darwin. It was thanks to certain evolutionary processes, during which the lifestyle of the ancient man and the climatic conditions in which he lived gradually changed, the blood could transform, acquiring new properties and changing its group at the same time.
Scientists are convinced that each of the blood groups appeared due to the adaptation of the human body to many different climatic, geological and even social changes that have occurred on Earth with the human species over many millennia. Thus, the first racial metamorphoses began when the first owners of the I blood group settled on the planet. The division into races, as well as the associated adaptation of humans to climate change, social environment and nutrition, was part of the driving force of evolution, which subsequently led to the formation of new blood groups.
Anthropologists argue that dividing humanity by race would be too limited an occupation, since the blood type is the most important and informative indicator of a person's individual characteristics. Thus, African and Indo-European with the same blood group can exchange blood freely and also have similar immune structures and digestive functions.

Features of blood groups
In order to determine the classification of the characteristics of blood groups, Japanese scientist Poshitake Nomi and American doctor Peter D'Adamo created a table by character type, based on a person's blood group.
Following this classification, the owners of the 0 (I) blood group are called "Hunters", based on the lifestyle of their ancestors who were engaged in hunting and gathering. So, according to Nomi's theory, the owners of the largest and most numerous blood group on the planet are representatives of the oldest blood group, which appeared 40,000 years ago. Carriers of 0 or the first blood group have a strong and persistent immune system. They also have a strong and strong-willed character, characterized by self-confidence and increased activity.
The second most common blood group is A (II). The owners of this blood group were called "Farmers", because they were the first who were forced to adapt to the new habitat due to population migration. Blood group A (II) appeared approximately 25,000-15,000 BC. During this period of time, people needed to establish ties with ever-expanding human populations and communities, learn to manage conflicts and cooperate with each other. Currently, in the owners of this blood group, a similar manifestation of evolution is expressed in character. So, they are sociable and easily adapt to new living conditions, without losing their inherent diplomacy and tolerance.
10-20% of the modern population are owners of the B (III) blood group, being distant descendants of the “Nomads” group. This blood group appeared as a result of the combination of different populations, as well as adaptation to new climatic conditions that took place just over 10,000 years ago. By nature, the “nomads” are open and optimistic, and they are also adventurous and do not tolerate injustice. Individualism makes it difficult for them to find friends.
AB (IV) blood group belongs to only 5% of people, appearing as a result of mixing Indo-Europeans and Mongoloids about 1000 years ago. According to Dr. Nomi's classification, people with this blood group have a gentle and meek character, as well as versatile interests.
Despite the fact that the connection of a particular blood group with a person's character has not been officially proven, its possible influence on the adoption of certain life decisions is still the subject of controversy in scientific and pseudo-scientific circles. What do you think about this? Is Poshitake Nomi's theory valid and worthy of further study?
