can be modeled from four ancestry components, which descended from a common ancestor in Mainland Southeast Asia, one being the "Ancestral Austroasiatic" component (AAA), which is more prevalent among modern Southeast Asians, and making up the exclusive ancestry among Austroasiatic-speaking Lua and Mlabri people. The early Austroasiatic speakers are suggested to have been hunter-gatherers but became rice-agriculturalists quite early, spreading from Mainland Southeast Asia northwards to the Yangtze river, westwards into the Indian subcontinent, and southwards into Insular Southeast Asia. Evidence for these migrations are Austroasiatic loanwords related to rice-agriculture found among non-Austroasiatic languages, and the presence of Austroasiatic genetic ancestry. According to a recent genetic study, Sundanese, Javanese, and Balinese, has almost an equal ratio of genetic marker shared between Austronesian and Austroasiatic heritages. Migration into India According to Chaubey et al., "Austro-Asiatic speakers in India today are derived from dispersal from Southeast Asia, followed by extensive sex-specific admixture with local Indian populations." According to Riccio et al., the Munda people are likely descended from Austroasiatic migrants from Southeast Asia. According to Zhang et al., Austroasiatic migrations from Southeast Asia into India took place after the last Glacial maximum, circa 10,000 years ago. Arunkumar et al., suggest Austroasiatic migrations from Southeast Asia occurred into Northeast India 5.2 ± 0.6 kya and into East India 4.3 ± 0.2 kya. Notes References Sources Adams, K. L. (1989).
