Not a type of study I usually cover, but it has a hidden gem in Figure 2, reproduced on the left, which shows a PCA plot of Indian men color-coded by religion and language.The existence of two clusters is kind of obvious, while their interpretation is not as dots of the same color appear in both clusters: a placement of these individuals in a global context might have been useful here. Things are clearer at the top cluster which shows a clear gradient anchored by Punjabi Sikh and Hindu Tamils on either end.
Also of interest is the group of isolated Muslim/Christian individuals on the left which deviate strongly from the mainstream; these probably represent exogenous elements that don't resembe the bulk of the Indian population.

most Christians are in india hindu converts,so they resemble the local hindu population say hindu tamils similar to christian tamils,marathi christians similar to marathi hindus.i think some of the outliers are anglo-indians,they are british descendants their mother tongue is english.other wise there is no chance for english-mother tongue in india.
