Subcontinental ancestry of the most basal Eurasian/Oceanian branches of the mtDNA phylogeny. South Asian and western Eurasian haplogroups are defined as described in the present study; for East Asian haplogroups, see Kong et al. (2003); for haplogroup P, see Forster et al. (2001); O and S are newly defined here on the basis of the data from Ingman and Gyllensten (2003). Potential coalescences based only on a single highly variable site are disregarded.
