I am very interested in history. But I am limiting it to groups high in rh negative blood. The Celts and Basques are known to be among the highest. The Berbers once were said to have 40% rh negative blood, but that was based on a study from the 1950s and the same group has since been re-examined and the percentage of rh negatives was less than 10% among them. So I am going to ignore them until we have new reliable data. Instead my focus has shifted towards the Bedouins of the Sinai Peninsula with said percentages of 18-30.
I have previously posted information regarding the y-DNA of Proto-Basques being replaced by Proto-Celtic y-DNA. Which makes it even more interesting for me to look back. Who were the Proto-Basques and what percentage of rh negatives were among them? Who were the Proto-Celts before entering the Pyrenees?
There are groups in other areas high in rh negative blood like a district in Saudi Arabia where almost 30% are rh negative. The Bedouins are high in y-DNA J1c indicating strong relations to Cohanim Jews and Sumerian ancestry from the 3rd Dynasty of Ur. There is a strong connection between the Proto-Basques and the ancient Sumerians as well. And also groups of men from the Caucasus if you want to focus on their original y-DNA. But since the Celts are the focus of this post, let’s move right into them:
When looking at the Yamna people from the Steppe, we have the highest representation of their y-DNA in Ireland and Scotland. And there are reports that their percentage of rh negatives may have been somewhere around 40%.
If this is correct, it might indicate Early Anatolian Farmers with their low percentage of 4% lowering the overall percentages of rh negatives in early Europe unless there were other factors playing a role.
The mtDNA frequencies between the Yamna and the group which once arrived in the British isles differs. Sumer, the Caucasus and the Black Sea region where the Yamnas once were are close to one another, so the thesis that there were high-rh-negative regions and tribes present makes a lot of sense. The claim that rh negative blood originated in Western Europe however does not. The Bedouins don’t show DNA indication of any migration from Western Europe.
