Kets are a primitive tribe in upper reaches of Yenisei River in Russia. Currently, there are only about 1200 of them. Before they came under control of Tsarist Russia in 17th century, this tribe was still in Stone Age and did not use any metal tools. Do not eat boiled food, eat raw venison.
2015 "Genomic study of Kets: a Paleo-Eskimo ethnic group with a significant ancient North Eurasian ancestry "Ancestors of population", article suggests that ancestor of Kets is ancient North Eurasian population of ANE (Ancient Northern Eurasia).
It has been established by autosomal analysis that Kets have a close genetic relationship with Selkup population of Siberia, and also have a certain genetic relationship with Shors and Enets of Siberia, belong to ANE (Old North Eurasian Old Eurasian Northern Population) offspring.
There are two sets of data on Y chromosome, one set is this article, 20 cat samples, paternal line includes Q (90%), I1 (5%), I2 (5%) and another set Data from 48 people in article "Western and Eastern Sámi Roots - A Story of Genetic Outliers Told by Mitochondrial DNA and Y Chromosomes" in 2004, paternal lineage includes Q (93.7%) and C (6.3%), in two datasets on type Q accounted for more than 90%.
The paternal type of ancient ANE (Ancient North Eurasian Ancient Eurasian Northern People), according to current data it should be R and Q, this group includes Aryans, which expanded widely in history, and cats are also descendants of this group.
Some entertaining short videos and articles on internet suggest that Kets are descendants of Jie people of ancient China. The author considers this impossible. There are several reasons for this:
① Judging by autosomal type, Kot people must be direct descendant of ancient population of ANE (Ancient North Eurasian Ancient North Eurasian) In terms of ancient population of my country, people belonging to this population mainly include Xiaohe site in Xinjiang. In 4th and 5th centuries AD, that is, era of emergence of Jie people in China, there is no pure ANE group such as Kote people in ancient DNA data of China and its environs. .
②The civilization of Jie people is relatively high and they are first people who believed in Buddhism in China. The Later Zhao rulers (Jie people) considered Buddhism to be state religion. The Kete stalled in stone tools. In this era, belief in primitive animism and sorcery, possibility of Iron Age Jie people degenerating back into Stone Age is basically zero.
③The kote people are farfetched like Jie family, meaning some people think their pronunciation is similar, but in fact their pronunciation is not "Je" but "Ke", and pronunciation is also much worse. Also, similar pronunciation of Chinese does not mean that two groups are related. The most typical are Chechen tribe in Outer Mongolia and Chechen Republic, a warring nation in Caucasus. The Chinese translation is same, but two actually have nothing to do with each other. Chechen a tribe in Outer Mongolia The name comes from Dayan Khan's grandson Nonohe, a descendant of "Chechen Khan", which means "Khan with great wisdom" in Mongolian, and translates into Chechen in modern Chinese. In past few years, many Internet jokes have taken literal meaning of text and started rumors that Caucasian Chechens are descendants of Mongolian western expedition, just such a ridiculous joke has spread quite widely on Internet.
