Reason Behind Having Different Blood Groups.

You don’t have the same sort of blood in your veins as your friends or perhaps even your family.

It is crucial to know your blood type because it might be useful for transfusions and other medical treatments.

The most frequent blood groups are A, B, AB, and O.

The antigens on the red blood cell’s surface identify the R group.

A blood group members’ cells display the A antigen, B group members display the B antigen, and AB group members display both the A and B antigens.

Due to the lack of an antigen, the O group is distinct.

But why do humans have various blood types is a mystery.

The straightforward response is that while the precise cause of this is unclear, other theories have undoubtedly surfaced.

Different blood groups evolved as a result of genetic mutations, but certain blood groups may have been established as a result of epidemics or environmental stress.

According to specialists, some blood types are stronger at fighting off particular diseases than others. For instance, malaria-infected cells do not adhere to O or B blood cells.

People with blood group A, however, are more likely to have significant damage due to the clumping of the cells after exposure to malaria.

This suggests that those with blood group A are more likely to die from malaria infection than those with blood groups B or O.

According to experts, this is typical in many diseases, and it is also more prevalent in areas where the blood types that are resistant to such diseases are more prevalent.

He explained that blood groups developed to combat sickness or environmental stress, and blood types that resist these stresses perform better.

On the other hand, scientists are still unsure of why most people’s blood cells carry the Rhesus (Rh) protein on their surface.

If the blood group is positive or negative, the protein controls that.

However, a large number of people have blood types that are A, B, AB, or O negative, meaning that they do not contain this protein on the surface of their blood cells.

An investigation on the causes of blood type negativity was conducted.

But they were unable to identify a cause, thus they came to the conclusion that either this resulted from natural selection, or that humans had two Rh kinds by accident.
