The History of the World through the Eyes of Blood VII

The highest percentage is found among some of the tribes still living in the Atlas Mountains of Morocco (40%). The next highest are the Basques, reported in different publications as having 25 and 32%, depending on location. The people of northwest Ireland, the Highland Scots and the western islanders of Norway all have between 16 and 25%, while the Lapps of Norway and Finland have between 5 and 7%. In addition, Cavalli-Sforza reports two small isolated populations of the same tribe, one in Chad and another in Senegal, each with about 25%. On his map, he shows an Rh-negative population in Chad, still living near the formerly enormous Chad lake. Only part of this lake still exists on the spot where the boundaries of Chad, Niger, Nigeria and Cameroon meet. These people may originally have been the sailors on Chad lake. Could it be that this is the original location of the Rh-negative population that then moved to Morocco and Algiers to become the Berbers? Or would it be the other way around?
