The term "Paleosiberian" refers to a group of indigenous peoples who inhabit the northeastern regions of Siberia in Russia. These groups include the Nganasan, Enets, Nganasan, and Yukaghir, among others. They are characterized by their unique languages, cultures, and traditional lifestyles, which are closely tied to the harsh Arctic environment. Paleosiberian languages belong to several distinct language families, including Yukaghir and Chukchi-Koryak. These languages are considered endangered due to the declining number of speakers. The Paleosiberian peoples have a rich cultural heritage, including traditional practices such as hunting, fishing, and reindeer herding, which are essential for their survival in the region.
