Abstract: The DNA was successfully extracted from the human bone samples excava ted from the ancient tombs of Chawuhu， which has been dated back to 2　500～ 3　000 years ago according to the feature of pottery and a series of ^{14C data. Part of the mitochondrial hypervariable region Ⅰ(364 bp) was amplifi ed and sequenced with four overlapping primers. In order to search their sharin g sequences and determine their pedigree, each sequence was searched and compare d with the database GenBank. Phylogenetic analysis indicated that there existed the admixture of Euro-Asian lineage in the east of Xinjiang prior to the time o f the Bronze Age.}

Key words: Chawuhu, ancient DNA, sequence analysis, polymorphism
