Ancient Mitochondrial Genomes Provide New Clues to the Origin of Domestic Cattle in China.

ABSTRACT: Cattle are one of the six livestock species that have occupied an important place in Chinese history. Previous ancient DNA studies have indicated that Chinese taurine cattle (Bos taurus taurus) are exotic, but the exact route and diffusion by which they were introduced to China is unknown. In this study, we extracted the mitochondrial genomes of 34 cases of ancient taurine cattle (from the late Neolithic to Qin and Han dynasties) excavated from sites in northern China and the eastern Eurasian steppe, and successfully obtained 14 mitochondrial genome sequences. The results of ancient DNA analysis reveal that with cultural exchange and trade, there was close genetic exchange between domestic taurine cattle in different regions. The haplotypes shared by domestic cattle have genetic con
