X2 mtDNA from Near East. 20,000 years ago
The Solutrean Hypothesis postulates that haplogroup X reached North America with a wave of European migration about 20,000 BP by the Solutreans,a stone-age culture in south-western France and in Spain, by boat around the southern edge of the Arctic ice pack.
In 2008 a team of genetic scientists published the following: "Here we show, by using 86 complete mitochondrial genomes, that all Native American haplogroups, including haplogroup X, were part of a single founding population, thereby refuting multiple-migration models." - Fagundes NJ, Kanitz R, Eckert R, et al. (March 2008). "Mitochondrial Population Genomics Supports a Single Pre-Clovis Origin with a Coastal Route for the Peopling of the Americas" Am. J. Hum. Genet. 82 (3): 583–92. doi:10.1016/j.ajhg.2007.11.013. PMC 2427228. PMID 18313026.
