Migrations out of the Upper Nile Valley
Paleoanthropologists have established a clearer picture of the connection between the ancestors of modern Siberians and some Native Americans using DNA.
Linguists have verified a connection between the Siberian language Ket and the language of the Navajo.
This is a different route of migration than that taken by other Old World peoples coming to North America across Eurasia and the Bering Strait. When it comes to mtDNA haplogroup X, there is no genetic trail across Eurasia. The dispersion of Haplogroup X is shown below. The greatest concentrations are indicated by the darker shade. MtDNA traces lineage by the mitochondria, received from mothers.
Only 7% of the Dene (Navajo) are in Haplogroup X, yet their language is related to Ket, a Yeniseic language spoken by a small Siberian population. This suggests that point of origin, genetic inheritance, and the language spoken must be analysed as separate features when studying a population.
