The Rh Negative blood type factor

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.

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.

Check out What Is Rh Incompatibility? for further useful info on this subject.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.
