A National Science Review study led by Fu Qiaomei's team analyzed 50 ancient genomes from eight Guizhou sites spanning ~12,000–300 years ago, showing Paleolithic Guizhou groups already carried East Asian northern ancestry, that the local basal-ancestry population was replaced before the Bronze Age by Austroasiatic-related people from central Yunnan, and that genetic differences between language groups persisted into historical times.
