The excavation of a frozen grave on the Kizil site (dated to be 2500 years old) in the Altai Republic (Central Asia) revealed a skeleton belonging to the Scytho-Siberian population. DNA was extracted from a bone sample and analyzed by autosomal STRs (short tandem repeats) and by sequencing the hypervariable region I (HV1) of the mitochondrial DNA. The resulting STR profile, mitochondrial haplotype, and haplogroup were compared with data from modern Eurasian and northern native American populations and were found only in European populations historically influenced by ancient nomadic tribes of Central Asia.
The probability of observing an individual with the Kizil skeleton STR profile was the highest in the two eastern European populations (Russia and Poland). Indeed, the likelihood that the Kizil skeleton STR profile occurred in these two populations was 10 times higher than in other European populations, 100 times higher than in eastern Asian populations, and about 100,000 times higher than in Indian populations.
