ooops.! sorry. I thought it was a typo.
Here's the Kets.
The Ket are the sole survivors of an ancient group believed to have originally lived throughout central southern Siberia. Today there are about 1100 Ket living mostly to the east of the middle reaches of the Yenisei River. Their extinct relatives included the Kotts, Assans, Arins, Baikots, and Pumpokols, all of whom lived further upriver (that is, further to the south) than the modern Ket before being assimilated to the Russians or their Native Siberian neighbors during the 17-19th centuries. (The Assans merged with the Ewenki to the East; the Arins and Baikots merged with the Turkic Khakas to the south; the Kotts became Russified by the 1840's.) Only the most northerly group has retained their language and ethnic identity into the 20th century. Formerly called Ostyak, or Yenisei-Ostyak (from a Turkic word meaning "stranger"), the group is now known as the Ket, from the tribe's word for "person." At one time the northern group of Ket were also known by their tribal name Imbak, while one of the southern groups was known as Yugh (pronounced "yook"; often written "Yug"). During the 1960's it was discovered that the Yugh were a separate ethnos with their own distinct, though related language. The Yughs, along with their language, dissappeared as a distinct ethnic entity by the late 1980's, leaving the Imbaks as the sole remaining Yeniseian people. The Ket, as well as the Yughs and their extinct relatives are called Yeniseians by linguists and ethnographers.
Linguistically and anthropologically, the Ket are one of the most enigmatic people of Asia. The Yeniseian peoples are thought to be descendents of some of the earliest inhabitants of Central Southern Siberia, while all of their neighbors seem to be relative newcomers. DNA studies show affinities to the peoples of Southeast Asia (Tibetans, Burmese, and others) not shared by other Siberian peoples. The linguistic evidence is even more striking. The Ket language, still spoken by about 600 of the Ket, is entirely different than any other language in Siberia. (The extinct Yeniseian languages, which were recorded in the 18th and 19th centuries by European exploreres, were all fairly similar to modern Ket.) Linguists believe that a proto-Yeniseian language existed 2000 or more years ago. This language, in turn, may have been related to such far-flung languages as Basque in Spain, Burushaski in northern India, the native languages of the Caucusus, as well as Tibetan and Chinese. Some linguists see an affinity between proto-Yeniseian and such Native American languages as Tlingit and Navajo, as well. Recently, linguists have posited a superfamily called Dene-Causasian which includes Yeniseian as one of its branches. If all of these languages do stem from some common ancestor, this ancient proto-language might have existed 20,000 or more years ago. Studying modern Ket is essential for piecing together these ancient relationships.
