The complete sequences of mtDNA D-loops from 362 individuals were analyzed in order to investigate the genetic diversity and differentiation of their lineages. The results indicated that all of the analyzed sequences were differentiated into four clear lineages (A, B, C, and D). Lineages C and D might originate from Lineages B and A, respectively. The genetic diversity of complete mtDNA D-loop of four lineages was very abundant. The 76 bp insertion and the 17 bp deletion were detected in the longest and the shortest sequences, respectively. The 76 bp insertion was a repeat like motif found in many other animals. Lineages C and D were differentiated into two subclades (C1 and C2) and (DI and D2), respectively. Lineage C might originate from Asia, and Lineage D might originate from Fertile Crescent.
