Mitochondrial hypervariable region I genetic data from ancient populations at two sites in Asia-Linzi in Shandong (northern China) and Egyin Gol in Mongolia-were reanalyzed to detect population affinities. Data from 51 modern populations were used to generate distance measures (Fst's) to the two ancient populations. The tests first analyzed relationships at the regional level and then compiled the top regional matches for an overall comparison to the two probe populations. The reanalysis showed that the Egyin Gol and Linzi populations have clear distinctions in genetic affinity. The Egyin Gol population as a whole appears to bear close affinities with modern populations of northern East Asia. The Linzi population seems to have some genetic affinities with the West, as suggested by the original analysis, although the original attribution of "European-like" seems to be misleading. We suggest that the Linzi individuals are potentially related to early Iranians, who are thought to have been widespread in parts of Central Eurasia and the steppe regions in the first millennium B.C., although some significant admixture between a number of populations of varying origin cannot be ruled out. We also examine the effect of sequence length on this type of genetic data analysis and discuss the results of previous studies on the Linzi sample.

Osseous and dental nonmetric (discrete) traits have long been used to assess population variability and affinity in anthropological and archaeological contexts. However, the full extent to which nonmetric traits can reliably be used as a proxy for genetic data when assessing close or familial relationships is currently poorly understood. This study represents the unique opportunity to directly compare genetic and nonmetric data for the same individuals excavated from the Egyin Gol necropolis, Mongolia.

The Yakuts, Middle Age Turkic speakers (15th-16th centuries), are widely accepted as the first settlers of the Altai-Baikal area in eastern Siberia. They are supposed to have introduced horses and developed metallurgy in this geographic area during the 15th or 16th century A.D.

In the present study, nuclear (autosomal and Y-chromosome short tandem repeats) and mitochondrial (hypervariable region I) ancient DNA data previously obtained from a 2,300-year-old Xiongnu population of the Egyin Gol Valley (south of Lake Baikal in northern Mongolia) (Keyser-Tracqui et al. 2003 Am.

DNA was extracted from the skeletal remains of 62 specimens excavated from the Egyin Gol necropolis, in northern Mongolia. This burial site is linked to the Xiongnu period and was used from the 3rd century b.c.
