The belongs one three major broad classifications or phyla sub-groups are separated from each other by large geographical distances. their nearest language-speaking sub-groups: "Mundari" sub-family East peninsular India "Mon-Khmers" Mainland Southeast We found be genetically distinct speakers, i.e. Mundaris Mon-Khmers, but relatively similar geographically proximal Tibeto Burmans. possible reasons genetic-linguistic discordance lie admixture history different migration events that originated Asia proceeded possibly towards at least two While ancestors today's were affected both, Khasis insulated second event.
