Narashimhan et al 2019 found Austroasiatic-speaking Munda tribals could not be modeled simply as mixture of ASI, AASI, ANI ancestry unlike other South Asians but required additional ancestry component from Southeast Asia. They were modeled as mixture of 48% AASI, 52% Austroasiatic-clad related to Nicobarese and 37% ASI ancestry, thus the ancestry profile of the Mundas provides an independent line of ancestry from Southeast Asia around the 3rd millennium BCE. Lipson et al. 2018 found similar admixture results in regard to Munda tribals stating ""we obtained a good fit with three ancestry components: one western Eurasian, one deep eastern Eurasian (interpreted as an indigenous South Asian lineage), and one from the Austroasiatic clade"". Lipson et al. 2018 further found that the Austroasiatic source clad (proportion 35%) in Munda tribals was inferred to be closest to Mlabri. Singh et al 2020 similarly found Austroasiatic speakers in South Asia fall out of the South Asian cline due to their Southeast Asian genetic affinity.
