The Bedouins of the Sinai Peninsula in Egypt have been mentioned in Kara Rogers´ work as being 18-30% rh negative. Are Berbers really 40% rh negative? is our article examining this a little bit further and as usual, more studies are needed to determine if in fact there are high percentages of rh negative blood amongst the Berbers or at least certain groups. ![]() The claim that the Ait Haddidu Berbers of Morocco are 40% rh negative has been made a long time ago, but there are also studies out there contradicting this. You can read more on this subject matter here: Is there a Basque-Jewish-Rh Negative connection? What is also interesting when examining old grave sites, that the further back you go in time, the higher the percentages of certain genetic markers become indicating that this reverse trend might show strong relationship to the ancient Hebrews as well as Sumerians. It could easily be that today’s Basques are an offspring of an original group which could have been 100 percent rh negative. The origin of the Basque people is of great interest and a key to researching the origin of rh negative blood. Spanish Basques appear to have the highest frequencies of rh negative blood in Europe also indicating that Spanish Basques are less likely to intermarry with Spaniards than French Basques are with the French. They are also the highest in rh negative blood in Europe when looking at larger groups other than maybe a few communities in Switzerland and the Netherlands with similar percentages if not higher than the Basques in France. Instead of focusing on what we do not know, here are a few things that we do know and should keep in mind when examining any types of theories or read something where a person claims to know something yet does not show any proof:ġ) The Basque people are considered the first Europeans. I was also informed that there was no cold hard evidence to back it up. Having consulted a few scientists, I was told that it was unlikely blood type O was the first blood type, but also that a few hundred thousand years ago rh negative blood might have originated in Africa, though the rh negative blood type factor is presented quite low on the African continent. This is an ongoing process and if you are heavily into genetic research, you can also read Rh Negative Origins. We have on this blog displayed several theories as well as evidence and indicators that might lead us into the right direction. These clues strengthen the hypothesis that low genetic diversity together with low reproductive success contributed to the disappearance of Neanderthals.Of great interest to people in general is the question “where do we come from?”. It confirms that these ancient hominins exhibited very little genetic diversity, and that they may have been susceptible to haemolytic disease of the fetus and newborn (erythroblastosis fetalis) - due to maternofetal Rh incompatibility - in cases where Neanderthal mothers were carrying the children of Homo sapiens or Denisovan mates. Do these two individuals bear testimony to interbreeding of Neanderthals and modern humans before the migration of the latter into Southeast Asia?įinally, this study sheds light on Neanderthal demographics. Extensive analysis covering other blood group systems turned up alleles that argue in favour of African origins for Neanderthals and Denisovans.Įspecially surprising is the discovery that the Neanderthals harboured a unique Rh allele absent in modern humans - with the notable exceptions of one Aboriginal Australian and one Papuan. ![]() While it was long thought that Neanderthals were all type O - just as chimpanzees are all type A and gorillas all type B - the researchers demonstrated that these ancient hominins already displayed the full range of ABO variability observed in modern humans. The findings bolster previous hypotheses but also offer new surprises. Of the 40-some known blood group systems, the team concentrated on the seven usually considered for blood transfusion purposes, the most common of which are the ABO (determining the A, B, AB, and O blood types) and Rh systems. In a new study, scientists from the CNRS, Aix-Marseille University, and the French Blood Establishment (EFS) have examined the previously sequenced genomes of one Denisovan and three Neanderthal females who lived 100,000 to 40,000 years ago, in order to identify their blood groups and consider what they may reveal about human's evolutionary history. Yet blood group systems were the first markers used by anthropologists to reconstruct the origins of hominin populations, their migrations, and their interbreeding. ![]() Despite prior sequencing of about 15 Neanderthal and Denisovan individuals, the study of the genes underlying blood groups had hitherto been neglected. The extinct hominin lineages of the Neanderthals and Denisovans were present throughout Eurasia from 300,000 to 40,000 years ago.
