60,000 years ago, humans arrived in Southeast Asia, mainly along the shorelines. However, it is unclear, according to archaeological and genetic research, how humans entered the northern parts of Southeast Asia, including China. Using mitochondrial DNA from populations in Burma, Myanmar and China, migratory events from Burma to southwest China’s (such as M54, M55 and M84) 25,000 to 10,000 years ago could be shown.
