Which other names have been used for Paleo-Siberian languages?

The term Paleo-Siberian languages refers to four genetically unrelated groups: Yeniseian, Luorawetlan, Yukaghir, and Nivkh.1

These languages have historically been referred to by the following names:

• Paleo-Asiatic: A common alternative designation for the group.23
• Hyperborean: A term used more rarely to describe these languages.2

These labels were popularized in the mid-19th century by the Baltic German zoologist and explorer Leopold von Schrenck, who hypothesized that these groups were remnants of a formerly widespread language family that had been displaced by Uralic and Altaic speakers. While modern comparative linguistics has determined that these groups do not form a single genetic family, the term remains a convenient way to categorize these distinct aboriginal languages in contrast to the surrounding Altaic languages and Russian.24
