Population dynamics in the Japanese Archipelago since the Pleistocene revealed by the complete mitochondrial genome sequences
Abstract The Japanese Archipelago is widely covered with acidic soil made of volcanic ash, an environment which is detrimental to the preservation of ancient biomolecules. More than 10,000 Palaeolithic and Neolithic sites have been discovered nationwide, but few skeletal remains exist and preservati...
