The apparent diversity of the Indian physical type is not due to "mixing" of various peoples coming from outside. Rather, it is because all the different (non-African) types were "generated", more or less, within greater India. From Kivislid 1999 above:

<b>More than ten per cent of the Indian mtDNA sequences do not belong to any of the continent-specific mtDNA haplogroups characterised so far</b> (Tables 1, 2). Nevertheless, the position of these lineages in the world-wide mtDNA phylogeny (Fig. 1) is not difficult to reveal: <b>they all stem out of a node that occupies a crucial position in the human mtDNA phylogenetic tree</b> (Kivisild et al., manuscript in preparation). It coincides with a hypothetical branching point connecting a large number of distinct, well-characterised mtDNA haplogroups. Theoretically, the existence of such a node was obvious already earlier and in one of the schemes it has been defined as R* (Macaulay et al. 1999). However, thus far it has existed as an âempty nodeâ. <b>Defining it as the founder of a super-haplogroup of mtDNA lineages allows one to say that it is an ancestral state of all western Eurasian sequences</b> belonging to haplogroups H, V, J, T, U and K <b>and has the same position relative to eastern Eurasian and Amerind sequences</b> belonging to haplogroups F and B (Fig. 1). The western Eurasian haplogroups listed above constitute about 90% of mtDNA variation in Europe, whereas an Asian-specific haplogroup B is close to fixation in some Polynesian populations (Lum et al. 1998; Sykes et al. 1995) and, together with <b>haplogroup F,</b> makes up a large portion of the mtDNA varieties found in <b>southeastern Asian populations</b> (Ballinger et al. 1992).
