After archaeological identification of ancient remains, ancient samples are expected to judge their Sus. Scrofa species and precise ages. The molecular biological experiments are designed to amplify fragmental mitochondrial DNA at both the physically isolated ancient DNA laboratory in China Agricultural University and another independent lab. The exact ages of ancient pig remains are detected by carbon-14 dating. And the mitochondrial genomes from different historical ancient samples will be investigated via high-throughput sequencing method. Then, the ancient samples are investigated along with modern Chinese native pig breeds on mitochondrial genomic level. By mining the variations in mitochondrial genome, we try to disclose the maternal origins of Chinese native pigs. Along with the time and region of domestication, the dispersal pattern and the evolutionary phylogeny of native breeds will be clarified by combining analysis genetic diversities with archaeological contexts. Furthermore, the functional annotations of ancient pig genomes will be used to reveal the evolutionary pattern of typical Chinese native breeds and make the contribution to uncover the mechanism of the breed-specific characters in Chinese native pigs.
