FIGURE 1: This DNA migration pattern map, created from compiled research on DNA populations around the world, demonstrates that the first Humans originated in Africa about 130-180 thousand years ago. Notes: a) mtDNA macro-lineage L is predominant in Africa, b) mt-DNA macro-lineages M and N are found throughout Eurasia and Australia, c) mtDNA lineages H, I , J, K, T, N, U, V, W and X are predominant in West Eurasia, d) mtDNA lineages A, B, C, D, E, F, G, M, P, Q and Z are predominant in Asia and Oceania, and e) mtDNA lineages A, B, C, D, and X are found in the Americas.
Haplogroup X represents a minor founding lineage in Native Americans
Approximately 97% of Native American mtDNAs belong to one of four major founding mtDNA lineages, designated A to D (Haplogroup A, Haplogroup B, Haplogroup C, Haplogroup D).
Unlike haplogroups A-D (Haplogroup A, Haplogroup B, Haplogroup C, Haplogroup D), Haplogroup X is also found at low frequencies in modern European populations.
There is a consensus haplogroup X motif that characterizes our European and Native American samples.
Among Native Americans, haplogroup X appears to be essentially restricted to northern Amerindian groups, including the Ojibwa, the Nuu-Chah-Nulth, the Sioux, and the Yakima, although we also observed this haplogroup in the Na-Dene- speaking Navajo. (#9837837#)
European and Native American haplogroup X mtDNAs, although distinct, nevertheless are distantly related to each other. (#9837837#)
Time estimates for the arrival of X in North America are 12,000-36,000 years ago, depending on the number of assumed founders, thus supporting the conclusion that the peoples harboring haplogroup X were among the original founders of Native American populations. (#9837837#)
To date, haplogroup X has not been unambiguously identified in Asia, raising the possibility that some Native American founders were of Caucasian ancestry. (#9837837#)
Here is the Caucasian linage: (haplogroup x)
Caucasia. A large region between the Black Sea and the Caspian Sea on the border between Eastern Europe and Asia. It is traversed by the Caucasus Mountains, from which it derives its name. In the north, Caucasia extends to the Kuma-Manych Depression and, in the south, to the northwestern border of Turkey and northern border of Iran. The region covers an area of over 440,000 sq km and in 1959 had a population of 27 million. Its northwestern part is settled by Ukrainians.
Caucasia consists of three geographical zones: (1) the steep Caucasus Mountains, known also as the Great Caucasus Range; (2) the steppe lowlands of Subcaucasia, which lies north of the mountains and is divided by the Stavropol Upland into the Kuban Lowland and the Terek-Kuma Lowland (see Terek region); and (3) the mountains of Transcaucasia (the Little Caucasus and the Southern Caucasian or Armenian Highland), which are south of the lowlands and are separated from them by the Rion Depression and the Kura Valley. The Caucasus mountain watershed divides Caucasia into two historical-political regions: (1) Transcaucasia, with an area of 190,000 sq km (encompassing Georgia, Azerbaijan, and Armenia) and a population of 14 million; and (2) Subcaucasia or northern Caucasia, with an area of 250,000 sq km belonging to the Russian Federation (encompassing Krasnodar krai, Stavropol krai, and the republics of Kabardino- Balkaria, North Ossetia, Chechnya, Ingushetia, and Dagestan) and a population of 13 million.
The area was generally protected from even extreme glaciation for the last 50+ thousand years, and shows at least some evidence of habitation as far back as 80,000 years

Haplogroup B was highest in the west and Midwest. Haplogroup C was found to be overall much less frequent but did show a slightly decreased frequency in Alaska. Haplogroup D followed the opposite pattern as C: frequencies were slightly higher in Alaska and lower in the remainder of Canada and the United States. Haplogroup X shows a higher frequency around the Great Lakes and Greenland than the remainder of North America."www.cstars.ucdavis.edu/ papers/ppt/greenbergetal2001d.ppt
