A full genomic study by Lipson et al. (2018) identified a characteristic lineage that can be associated with the spread of Austroasiatic languages in Southeast Asia and which can be traced back to remains of Neolithic farmers from Mán Bạc (ca. 2000 BCE) in the Red River Delta in northern Vietnam, and to closely related Ban Chiang and Vat Komnou remains in Thailand and Cambodia respectively.
