It is assumed that Rhesus negative blood type is specific to group O which is the purest type of blood and the rarest. This seems to explain a story about a tribe in China that dies when relocated to lower altitudes.įascinatingly, they do not require the adjustment most would require when moving to higher altitudes. Rhesus negative people have a greater oxygen capacity thus are more adaptable to higher altitudes like the mountains. This explains the weakness in Rhesus negative people against several types of diseases and illnesses. This specific antigen is found on the surface of the erythrocytes exclusively in Rhesus positive blood type individuals. Rh negative blood type lacks an antigen that perpetuate the release of antibodies in the event of an invasion by viruses and bacteria. This is a major disadvantage for people who belongs to the Rh negative blood group. It is commonly referred to as ‘hemolytic disease’ or death of the unborn. Blood that lacks the D antigen tends to reject it’s own unborn baby especially if the baby is Rhesus positive. This is a very important factor especially for pregnant women. Studies show that the 15% of humans who lack the rhesus factor are gifted with natural resistance to HIV, small pox and bubonic plague.īy being resistant to these diseases, it means that they are less susceptible to suffer from them as opposed to those with the Rhesus factor. Better natural resistance to particular disease. This results in having them being more picky when it comes to food preferences. People with the Rh negative blood type are more prone to be affected by allergies, especially food allergies. Lacking Rh factor can lead to problems especially in cases where blood transfusion or organ transplant is needed urgently. The remaining 85% are Rh positive, making them more favorable. In reference to whole of the world’s population, only about 15% lack the rhesus factor. It leads to a build up of antibodies in the mother’s blood that causes it to fight or react to pregnancy of the second child resulting to death. This happens most especially when the child picks up the rhesus factor from the father that differs from that of the mother’s. In situations where a couple have different rhesus factor blood types, it puts their children at risk. The fact that a number of people lack this factor is a puzzling phenomenon that tends to defy the evolution story arising the question on where did they come from? 2. The term is derived due to the first discovery of the protein substance in the blood of Rhesus monkeys. Rhesus factor, referred to as the Rh factor, is a protein in the human blood. The Rh negative blood type is not a ‘mutation’. Nobel Laureate Karl Landsteiner was involved in the discovery of both the AB0 and Rh blood groups.Rh Negative Blood Type 1. A person with Rh+ blood can receive blood from a person with Rh- blood without any problems. But a person with Rh- blood can develop Rh antibodies in the blood plasma if he or she receives blood from a person with Rh+ blood, whose Rh antigens can trigger the production of Rh antibodies. Those who haven’t are called Rh-.Ī person with Rh- blood does not have Rh antibodies naturally in the blood plasma (as one can have A or B antibodies, for instance). This is also an antigen and those who have it are called Rh+. Many people also have a so-called Rh factor on the red blood cell surface. Group O blood is known as the universal blood type, as it can be given to patients of any blood group. Not all blood groups are compatible with each other and the success of modern transfusion medicine depends on classifying and matching donors and patients correctly. There are therefore eight different main blood groups. All donors belong to one of four blood groups: A, B, AB or O. You are also classified as either Rh positive or Rh negative.
