Tarim mummies

The Tarim mummies are a series of mummies discovered in the Tarim Basin in present-day Xinjiang, China, which date from 1800 BCE to the first centuries BCE. The mummies, particularly the early ones, are frequently associated with the presence of the Indo-European Tocharian languages in the Tarim Basin,although the evidence is not totally conclusive and many centuries separate these mummies from the first attestation of the Tocharian languages in writing. Victor H. Mair's teamconcluded that the mummies are Europoid, likely speakers of Indo-European languages

Han Kangxin, who examined the skulls of 302 mummies, found the closest relatives of the earlier Tarim Basin population in the populations of the Afanasevo culture situated immediately north of the Tarim Basin and the Andronovo culture that spanned Kazakhstan and reached southwards into West Central Asia and the Altai.

It is the Afanasevo culture to which Mallory & Mair (2000:294–296, 314–318) trace the earliest Bronze Age settlers of the Tarim and Turpan basins. The Afanasevo culture (c. 3500–2500 BCE) displays cultural and genetic connections with the Indo-European-associated cultures of the Eurasian Steppe yet predates the specifically Indo-Iranian-associated Andronovo culture (c. 2000–900 BCE) enough to isolate the Tocharian languages from Indo-Iranian linguistic innovations like satemization.
In 2009, the remains of individuals found at a site in Xiaohe were analyzed for Y-DNA and mtDNA markers. They suggest that an admixed population of both west and east origin lived in the Tarim basin since the early Bronze Age. The maternal lineages were predominantly East Eurasian haplogroup C with smaller numbers of H and K, while the paternal lines were all West Eurasian R1a1a. The geographic location of where this admixing took place is unknown, although south Siberia is likely. In 2012 – 11 R1a1a, 1 K*
