Most people who have the Rh blood type are Rh-positive. There are also instances, however, where people are Rh-Negative. Health problems may occur for the unborn child of a mother with Rh-Negative blood when the baby is Rh-Positive. This has led some to suggest that Rh-Negative blood must be of a non-human origin. Theories range from supernatural ones such as being of divine descent or membership in a divinely chosen people-group, to more scientific or pseudoscientific explanations such as interbreeding with extraterrestrials. The majority of scientists who have studied the blood type have concluded that it is most likely just a random mutation. This explanation seems to be the one most consistent with available evidence and the one that is most able to withstand Occam’s Razor.
What is unusual about Rh-Negative blood is that the gene for it is surprisingly common despite being potentially harmful. When a woman who is Rh-Negative is pregnant with a child that is Rh-Positive, the blood from the mother is essentially toxic to the child. To some people, this looks like the mother’s body is rejecting the baby – which has led them to suggest that perhaps the reason for the rejection is incompatibility based on the mother and child being of different species. Others suggest that lineages with the gene for Rh-Negative blood are merely special in some way and were not meant to be mixed with lineages which are predominantly Rh-Positive.

Rh-Negative Blood LineagesOne population which contains an unusually high frequency of the gene for the Rh-Negative blood type are the Basques from northeastern Spain. The Basques have the highest incidence of the gene out of any population in the world. The Basques also speak a non-Indo-European language and have genetic markers that pre-date the rise of agriculture. This has led to speculation that Rh-Negative blood is related to Cro-Magnon ancestry going back to the upper Paleolithic period in Europe.
Among the more exotic theories is the idea that the Rh-Negative gene represents a separate branch of humanity that intermarried with the branch that came out of Africa. One blogger has gone as far as to say that those with Rh-Negative blood are descendants of the Hyperborean race, which they believe to be the original human race. Followers of this idea believe that this race was blonde-haired and blue-eyed and included most major spiritual teachers in history, including Jesus.
The Role of Genetics in Rh-Negative BloodThis unusual trait can, however, also be explained in terms of relatively mundane human genetics and natural selection. One possibility is that the gene for Rh-Negative blood has some sort of selective advantage that outweighed the negative consequences of having Rh-Negative blood.
A well-known example of this phenomenon would be the case of sickle cell anemia and malaria. A large percentage of the population in west Africa where malaria is common consists of carriers of the gene for sickle-cell anemia, although they don’t have the disease themselves. The reason is that just carrying the gene for sickle cell anemia gives the person carrying it immunity to Malaria. Although sickle-cell anemia is harmful, even deadly, carrying the gene gives a selective advantage and therefore it is much more common than would be expected.
The Basques have an ancestry that, with other European groups, goes back to the European Upper Paleolithic. Yet the Jews ultimately descend from relatively recent Middle Eastern populations. This would make sense if the reason for the prevalence of the gene was because both the ancestral Basque and Jewish populations originated in an environment with similar selective factors rather than being of a common lineage.

Could Rh-Negative Blood Come from Extraterrestrials?The extraterrestrial explanation is even more problematic because the Rh-Negative gene is clearly a variation of an otherwise completely human gene. Unless it was specifically engineered by extraterrestrials from a pre-existing human gene, it is unlikely that it comes from anything other than Homo Sapiens .
The other problem with the Rh-Negative blood type being the result of hybridization with extraterrestrials is that extraterrestrials are likely to have a completely different biology and genome than human beings. Their genome might not even be based on DNA – but something else such as RNA, or some exotic form of genetic storage that never evolved on Earth. This would make any viable hybrids very improbable if not impossible. As the astronomer Carl Sagan would have put it, it would be easier to make a human-tulip hybrid, than a human-extraterrestrial hybrid.
