The Rh negative blood factor is said to have originated 35,000 years ago in the Basques people in the Pyrenees Mountains. It is called a Basques gene. Many studies that I have read stated that the gene was carried from the Basque area to Scotland, Ireland and on to the British Isles.
The Rh negative blood factor is recessive and although a person can be Rh positive, they can still carry the gene if they have a Rh negative parent.
Quoted from the Cayce website:
In the Cayce readings, the Atlante-ans migrated from their last island prior to 10,000 B. C. and went to Egypt, North American and the Pyrenees Mountains. Some went to the area of the Gobi. Archaeologist have speculated that the Basques moved from southwestern Europe in between 13,000 and 8,000 B.C.. This group of hunter gathers were of the haplogroup X. Researchers have discovered that 3 percent of modern and ancient Native Americans have this haplogroup. The X haplogroup has been identified in the Middle East and a tribe that lived in the Altaic Mountains of the Gobi. These areas are specific to where Cayce stated that the survivors had fled prior to 10,000 B.C.
Levi B Gritts that was chief in 1920 of the Cherokee Nation, and later became a Cherokee historian taught that the Cherokee came from an island in South American and that this island sank after the elders misused “white fire”. Some other Cherokee holy people taught that the Cherokee were a Medicine Clan called the As-saga and that this group went into the Great Smokey Mountains to preserve the ageless wisdom combining with others to become the Cherokee people, which are called the principal people.
The Cherokee have a distinct difference in dialect, though they are from Iroquois origins. So this solidifies the information of a gathering of different peoples.
There is much speculation by Archaeologist that not all Native Americans came through the Bering Strait to North American. It is clear by testimonies of the Cherokee holy people and Mt DNA that this is true..
