Table 2. Analysis of molecular variance (AMOVA).

Grouping (number of groups)	Among groups	Among populations within groups	Within populations
Language (5)	17.9	3.8	78.3
Geography (5)	3.1	29.3	67.6

The language groups used for the analysis were Indo-European, Dravidian, Austroasiatic, Tibeto-Burman and Austronesian, while, geography was divided in to East Asia, Southeast Asia, Northeast India, East Bengal and West Bengal. All p-values were significant (P<0.05) except for the Among groups-geography (3.1; p = 0.12).
