Genetic studies have shown that such rare people first appeared in Europe about 35,000 years ago. There are a number of versions about the roots of this difference. Perhaps the first owners of a negative Rh factor were a group of people who lived in Europe, England, Spain or France.
However, the most popular theory indicates the unearthly origin of the DNA of these people, since the blood of such exceptional individuals is rare, different from the general pattern of humanity. At the same time, they have a number of physical and mental characteristics that modern science is not yet able to explain.
The main difficulty exists for women with a negative Rh factor during pregnancy. If the fetus is Rh positive, this can lead to Rh conflict, which sometimes ends in the death of the child. Therefore, in such cases it is necessary to carry out special immune therapy.
