How do the Paleo-Siberian languages differ from Eskimo-Aleut languages?

The Paleo-Siberian and Eskimo-Aleut languages are distinct linguistic groupings with different classifications and historical contexts.

Paleo-Siberian Languages
The term Paleo-Siberian languages refers to a grouping of four genetically unrelated language families spoken in Asian Russia: Yeniseian, Luorawetlan, Yukaghir, and Nivkh. These are often considered remnants of languages that were more widely spoken in the Siberian north before the expansion of other language groups, such as the Tungusic and Samoyedic languages.12

Eskimo-Aleut Languages
In contrast, the Eskimo-Aleut languages (or Eskaleut) constitute a distinct language family. This stock is considered isolated, as there is no conclusive evidence linking it to other language families. It is divided into two main branches:23
* Eskimo: Comprising the Inuit and Yupik divisions, spoken across the Arctic from Greenland to Siberia.43
* Aleut: Consisting of the Unangam Tunuu language.3

While some Eskimo-Aleut languages are spoken in eastern Siberia, they are linguistically separate from the Paleo-Siberian groups.42
