ABSTRACT

The domestication of pigs in East Asia is believed to have been independently established in several regions of China, including the Yellow River basin, before spreading to areas such as Korea and Japan. However, this view is based on archaeological excavation reports and has not yet been fully clarified from a genetic perspective. This study conducted a haplotype-based network analysis on the mitochondrial DNA D-loop region (138 bp) of ancient and modern wild and domesticated pigs previously reported in Korea, Japan, and China, aiming to genetically explore the origins and spread of pig domestication in this region. As a result, haplotypes such as H1, H2, H3, and H6-reported in Chinese pigs-were found to exhibit characteristics corresponding to the ancestors of domesticated pigs in East Asia, confirming through network analysis that China was the early center of pig domestication in the region. On the other hand, the establishment and spread of domesticated pigs in Korea and Japan remain unclear even through this analysis, indicating the need for further supplementary research
