Tocharians raw DNA 23andme format

The Tocharians were an ancient Indo-European people who inhabited the Tarim Basin in what is now Xinjiang, China, from around the early 1st millennium BCE. They are most famously known through the Tocharian A and Tocharian B languages, which form a distinct branch of the Indo-European language family and are among the easternmost examples of Indo-European tongues. These languages were preserved in Buddhist texts dating from around the 6th to 8th centuries CE and were written in a version of the Brahmi script.

For this video, I gathered 7 Tocharian and proto Tocharian genomes from Xinjiang. 6 samples are dated to the bronze age and 1 sample is dated to the Iron age.

According to QPADM analysis, these people descend mainly from the Afanasievo culture, an eastern offshoot of european steppe herders that predates the spread of Indo-Aryan languages in central asia by a millenia. They were not Iranic speakers, but rather an extinct group of Indo-Europeans.

In terms of paleolithic admixture, these people were heavily ancient north eurasian. There are currently no ethnicities that are as heavily ANE as these people were.

A mesolithic QPADM run revals these people were 51% Ancient North Eurasian, 23% Caucasian hunter gatherer, which also descends in part from the Ancient North Eurasians, 12% Western Hunter Gatherer, and 13% East Asian.

An Fst analysis of these samples showed that their closest modern relatives, in terms of genetic distance, are Tajiks and Kazan Tatars. However, it's important to note that the Fst and f2 values reported here have been standardized. I applied standardization by subtracting the lowest observed Fst and f2 values from all corresponding values. This was necessary because the file used in this run was only a partial diploid representation, rather than a true diploid genotype, which resulted in significantly inflated Fst and f2 scores.
