Sources on genetics Hello Regarding the Cavali Sforza source do you have any concerns in addition to the work being incomplete I m not sure as to when i ll be approaching the admins but when i do i would like to forward your thoughts on it if you are going to take a wiki break In case you happen to be active i ll probably post a link to the discussion By the way i came across another source where the output is pretty clear obvious It s about the Iyengar community in general showing the affinity between two groups in the form of clusters See here Fig 1 is about the various castes of tamil nadu in the form of clusters which shows the relative similarities distances from the other groups of tamil nadu which in my opinion only gives a narrow view of the picture However Fig 2 is about 43 global populations which gives a wider insight of genomic affinites according to which Iyengars as a whole form a separate cluster with show close affinities to European Americans white caucasian americans According to Fig 2 even Iyers other high ranking non brahmins who according to Fig 1 were closer to Iyengars are distanced from the Iyengars and European Americans who seem to be forming a separate cluster Please give your thoughts on this I hope our quarrels in the past do not affect the constructive discussions at present Once you respond please try to post a talkback template linking to this discussion in my talkpage Thank you
