Although I have done alot of research, I have yet to find any place that has any answers to where the Rh Negative blood factor originated. Being an O- myself, i'm very interested in finding out. What I do know is that the Rh+ factor originates from our long time ancestores, monkeys, hence Rh for Rhesus monkey which is where the Rh+ factor was discovered. So, the question is, where did the negative factor come from? Many people believe that Adam and Eve had O-, becaus it is considered to be "pure blood". However I am not here to argue that I have pure blood or anything like that, I just want to know if anyone has any answers for this question.
I just joined the Forum site, and this topic (Rh Incompatibility) was one I immediately searched for, because this incompatibility existed between my mother and myself when I was a fetus, and led to me being removed from her 2 months premature via a Caesarian Section operation to prevent the onset of blood poisoning.
