Both the Yeniseian and the Na-Dene ruled out by simple probability. Two language families might families have traditionally been considered isolates, that is, share one or two accidental resemblances, but they would not families with no known relatives (2, 3), and many linguists share 36, so the only plausible explanation for these resem- maintain that “there is no trace of genetic connections be- blances is common origin. These 36 etymologies represent tween New World and Old World stocks” (4). The present what seem to me the most secure evidence for the genetic paper presents evidence that the Yeniseian and Na-Dene fam- connection of these two families.

If this hypothesis is correct, it would locate the One of the most compelling pieces of evidence for the source of one of the three migrations to the Americas posited Yeniseian–Na-Dene connection is the word for “birch bark.” by Greenberg, Turner, and Zegura (5). The Ket word for “birch bark” is qé?y, and this is distinct To my knowledge, no one has ever directly compared the from the Ket word for “birch tree” (u2$ s@).
