• Haplogroup R2 is present both in Dravidian and Indo-European populations, implying that R2 has a pan-Indian presence, and is not restricted to any linguistic group.
• The frequencies of R2 seem to mirror the frequencies of R1a (i.e. both lineages are strong and weak in the same social and linguistic subgroups). This may indicate that both R1a and R2 moved into India at roughly the same time or co-habited, although more research is needed.
• R1a1 and R2 haplogroups indicate demographic complexity that is inconsistent with a recent single history.
• R2 has a particularly strong presence in the Indian states of West Bengal, Uttar Pradesh and Gujarat, and in the area of Mumbai (Bombay).
• Contrary to the findings of Spencer Wells, the paper claims that there is no evidence that Central Asia was the source of the R1a and R2 lineages in India. The theory that Central Asia could have been the recipient of the two lineages from India should not be ruled out.
• Some of the other studies like Bamshad et al., 2001, Kivisild et al., 2003 found Haplogroup 1(the old representation for non-R1a1 Haplogroup R subclades) at around 40% among Telugus of coastal Andhra Pradesh. The identification of this Haplogroup with R2 is confirmed from Sanghamitra Sahoo et al., 2006 study which observed R2 ranging from 35% to 55% among non-Brahmin castes of this region.

The results of genome analysis in India is changing in such it seems everything is possible .I think any study about human beings can't be devoid of politics,what who studied wanted to prove and the power structure.I think Mischelle Fucoult was correct every discourse about us is revealing a power center , it's not an objective knowledge.We must understand this whole study with deep sense of realization of the tragedy of the impossibility of ourselves being objective( honest or true ?) enough.
