The highest concentration of RH negative blood occurs in the Basque people of Northern Spain and Southern France, and in the Eastern/Oriental Jews. Only 15% of the entire worlds population are known to have the RH negative blood factor. While it is known that RH negative blood - (type O) is the purest blood known to mankind, it is not known from where the negative factor originates. The majority of people, especially the native people of the Americas have type O blood, except the Blackfoot Indians who have 82% type A blood. These native people are the only tribe to have this high concentration of A blood - most other American Indians have 80% type O. It is the rh negative factor that makes the blood pure.
