The Middle Eastern or Canadian origins of X2a mtDNA
Soon we will know that the Ojibwe are truly Ani-Shin-Abe. Original and 1st peoples who have existed since the very beginning, in Canada and migrated much much later to Asia and the Middle East.
Distribution maps are worth 1000 words. Looking at the above concentrations it is clear that the areas of Central and North East Canada and the Middle East are connected via the maternal X DNA distribution. In human mitochondrial genetics, Haplogroup X is a human mitochondrial DNA (mtDNA) haplogroup. It has a widespread global distribution but no major regions of distinct localization.
Origin : mtDNA-based chart of possible large human migrations. The genetic sequences of haplogroup X diverged originally from haplogroup N, and subsequently further diverged about 30,000 years ago to give two sub-groups, X1 and X2.
Distribution : Overall haplogroup X accounts for about 2% of the population of Europe, the Near East, and North Africa. Sub-group X1 is much less numerous, and is largely restricted to North and East Africa, and also the Near East. Sub-group X2 appears to have undergone extensive population expansion and dispersal around or soon after the last glacial maximum, about 21,000 years ago. It is more strongly present in the Near East, the Caucasus, and Mediterranean Europe; and somewhat less strongly present in the rest of Europe. Particular concentrations appear in Georgia (8%), the Orkney Islands (in Scotland), (7%) and amongst the Israeli Druze community (27%). Subclades X2a and X2g are found in North America, but are not present in native South Americans
Druze: The greatest frequency of haplogroup X is observed in the Druze, a minority population in Israel, Jordan, Lebanon, and Syria, as much in X1 (16%) as in X2 (11%). The Druze also have much diversity of X lineages. This pattern of heterogeneous parental origins is consistent with Druze oral tradition. The Galilee Druze represent a population isolate, so their combination of a high frequency and diversity of X signifies a phylogenetic refugium, providing a sample snapshot of the genetic landscape of the Near East prior to the modern age.
North America : Haplogroup X is also one of the five haplogroups found in the indigenous peoples of the Americas. Although it occurs only at a frequency of about 3% for the total current indigenous population of the Americas, it is a bigger haplogroup in northern North America, where among the Algonquin peoples (Ojibwe) it comprises up to 25% of mtDNA types. It is also present in lesser percentages to the west and south of this area—among the Sioux (15%), the Nuu-Chah-Nulth (11%–13%), the Navajo (7%), and the Yakama (5%) - Wikipedia
