And now there's only one? What happend to the others?
About 68% of Europeans have DNA haplogroups that are from the Iberian Ice Age Refuge, yDNA = R1b and mtDNA = 'H'.
I think it is informative to note the haplogroups amoung the Guanches of the Canary Islands. When the Ice Age began to end, the refugees migrated all over Europe and at the same time into Northern Africa.
My guess is that at one time, Northern Africa was probably inhabited by White people who mixed with Black Africans became Berbers and etc.
"The Guanches are the mysterious natives of the Canary Islands. They were conquered by the Spaniards during the turn of the 15th century. Tall, blond and blue-eyed, the Guanches have long intrigued the anthropologists, for blond natives are rarity. According to the reliable Encyclopedia Britannica, the Guanches "are thought to have been of Cro-Magnon origin... and had a brown complexion, blue or gray eyes, and blondish hair."
