Researchers who analyzed indigenous languages in the U.S., Canada and Russia say their ancestors lived together in the Bering Strait before migrating to their present locations.
Mark Sicoli of Georgetown University and
Gary Holton from the University of Alaska Fairbanks compared 37 languages in the
Na-Dene family with two languages in Siberia that belong to the
Yeniseian family. Their research indicated that a language spoken by the ancestors of both groups was used in the Bering Strait as long as 14,000 years ago.
From there, some groups migrated to Alaska, Canada and the U.S., where they now speak languages like
Navajo,
Tlingit and
Dene. According to the researchers, other groups went to Siberia, according to researchers, where
Ket is spoken.
The study comes on the heels of another one that claims the ancestors of Native Americans lived in the Bering Strait for a prolonged period of time before migrating to North and South America. Researchers believe the lengthy stay in
Beringia might explain why Native Americans are different from Asian populations.
The language study, however, makes the case that some groups went "back" to Siberia and other Central Asian locations. A different researcher has proposed a
Dené–Yeniseian family to include languages like Navajo and Ket.
