It is located to the northwest of modern Anyang city in Henan province, China. It is one of the oldest and largest archaeological sites in China, famous for the discovery of oldest Chinese writings, the oracular bones. Historical and archaeological evidence suggests that the Shang dynasty is first recorded dynasty of China (Li, 1985). The dynasty is also known as the first monarchical slave state in Chinese history. Until today, no DNA research had been done on the human remains of Yinxu. Materials and Methods 0 0 - 500 m 500 - 1000m Neolithic Period 1000 - 2000 m Bronze Age Iron Age 2000 - 3000 m 3000 - 5000 m > 5000 m Russia Helongjiang Mongonlia Xinjiang Jilin YBLK Inner Mongolia Gansu UXC DDZ JHL DDJ XDZ North Korea YXSG ZKG Liaoning The archaeological and anthropological evidence show that people had lived in the Central Plain since Neolithic period, aboriginal population grew fast and immigrants might have poured in as the settlements developed rapidly. It is possiblethat the society of Yinxu was composed of individuals coming from various regions during Shang Dynasty. Therefore we analysis the craniometric data of the Yinxu and related ancient Chinese populations with Euclidean distance (Figure 2). The Yinxu and DDZ groups clustered together firstly, then they clustered with ZKG groups. The distance between Yinxu and JHL, JGZ and XDZ groups were significant. The result of this cluster analysis is similar to Figure 3 Dendriform representaion of cluster analysis based on Dij values the distance reflected in pairwise Fst value, suggesting there is a close genetic affinity between the Yinxu and 0 5 10 15 20 25 2 DDZ-I DDZ population, without major geographic barriers, YX-B 10 HB 13 population movement and cultural exchanges potentially ZKG 8 could occurbetween the West Liao-River valley and Central YXSG 1 2 9 UXC Plain (Li H et al, 2011). Furthermore, considering the JJL 11 TJZ 5 topographical features of location of Anyang, it is possible YBLK-M 6 that the Yinxu ancient residents contained the culture and JGZ 4 14 absorbed the genetic components of various contemporary DDJ XDZ 7 NHL 1 populations who lived in north China.

The DNA extraction combined a complete demineralization process with the QIAquick PCR Purification Kit (Qiagen, Hilden, Germany) according to the manufacturer’s protocol. The fragments (393bp) of the mtDNA hypervariable region I (HVR I) were amplified, sequenced and analyzed on the ABI PRISM 310 automatic sequencer. According to the East Asian mtDNA classification tree (Kivisild et al., 2002), the haplogroups were assigned using hypervariable region and coding region SNPs data. Haplogroups M, F, D, C, G and B were examined using amplified product-length polymorphisms (APLP) method. Haplogroups A, M10, N9a, and Z were identified by sequencing. Sequence alignments were Abbr.

They belonged to 30 haplotypes. Using coding region and HVR II SNPs data, combined with HVR I sequences, all haplotypes were attributed to these (sub) haplogroups: A, B, C, D, F, G, M10, N9a, and Z, which all belong to the East Eurasian pool of mtDNA lineages. The dominant haplogroup in the Yinxu population was D(43.33%) shared by 13 individuals who were associated with 13 different haplotypes. The northern East Asian-dominating haplogroups (A, C, D, G and Z) accounted for 80% of Liujiazhuang population.

The result of AMOVA between Yinxu and modern Chinese populations (Table 2) shows that Yinxu population is not significantly different (Fst value: 0.0073, P> 0.05) from northern Han Chinese, but significantly different (Fst value> 0.03, P< 0.05) from southern populations. Compared with Frequency distribution of mtDNA haplogroups in modern Chinese populations, the Yinxu populations bore a high similarity to some northern Han and Tibeto-Burman populations. On the basis of principal component analysis of mtDNA haplogroup frequencies (Figure 5), the Yinxu population pooled into the cluster Figure 5 PCA of mtDNA haplogroups frequencies of Yinxu populaion and modern Chinese populaions formed of the northern Han, Tibeto-Burman 1.0 and Altaic populations.

Most burials at this cemetery are moderate in tomb size and number of grave goods, some of the burials are relative poor. The characteristics of grave goods showed their affiliation with Yinxu and the tomb owners were probably citizens of the city. This assemblage constituted a representative sample to study the genetic structure of Yinxu commoners. 800 km Because few genetic analysis results have been published on ancient Chinese populations, frequency distribution of mtDNA haplogroups can not be analyzed. AMOVA was used instead to evaluate maternal genetic differentiation between Yinxu and other ancient Chinese (Figure 2). The Fst value between Yinxu and DDZ populations was the lowest (-0.00016), The Fst value between Yinxu and ZKG populations was second to the lowest. The Yinxu and HB populations presented a lower and nonsignificant pairwise Fst value. However, the highly significant value was observed between Yinxu and other historical period populations. 0.0 0.5 1.0 PC 1 Conclusion Yinxu population had genetic communication with various contemporary populations and significantly contributed to the formation of the matrilineal genetic heritage of the modern northern Han Chinese population. However, we need research more thoroughly to draw a further conclusion. The Y-chromosome DNA research is still ongoing, and will provide more genetic information of Yinxu residents soon.
