Altaic has not been proven to be a language family, a phylogenetic unit. It may be a Sprachbund. Paleosiberian is simply a geographic term of convenience. Here, these two terms are listed just to serve as portal-like starting points – without suggesting genetic considerations.
Geographical distribution of Samoyedic, Finnic, Ugric and Yukaghir languages
The Buryats number approximately 436,000, which makes them the largest ethnic minority group in Siberia. They are mainly concentrated in their homeland, the Buryat Republic, a federal subject of Russia. They are the northernmost major Mongol group.
Buryats share many customs with their Mongolian cousins, including nomadic herding and erecting huts for shelter. Today, the majority of Buryats live in and around Ulan Ude, the capital of the republic, although many live more traditionally in the countryside. Their language is called Buryat.
Four small language families and isolates, not known to have any linguistic relationship to each other, compose the Paleo-Siberian languages:
1. The Chukotko-Kamchatkan family, sometimes known as Luoravetlan, includes Chukchi and its close relatives, Koryak, Alutor and Kerek. Itelmen, also known as Kamchadal, is also distantly related. Chukchi, Koryak and Alutor are spoken in easternmost Siberia by communities numbering in the thousands. Kerek is close to extinction, and Itelmen is now spoken by fewer than 100 people, mostly elderly, on the west coast of the Kamchatka Peninsula.
2. Yukaghir is spoken in two mutually unintelligible varieties in the lower Kolyma and Indigirka valleys. Other languages, including Chuvantsy, spoken further inland and further east, are now extinct. Yukaghir is held by some to be related to the Uralic languages.
3. Ket is the last survivor of a small language family on the middle Yenisei and its tributaries. It has recently been demonstrated  to be related to the Na-Dene languages of North America. In the past, attempts have been made to relate it to Sino-Tibetan, North Caucasian, and Burushaski.
4. Nivkh is spoken in the lower Amur basin and on the northern half of Sakhalin island. It has a recent modern literature and the Nivkhs have experienced a turbulent history in the last century.
