Are Indians descendants of Aryans? https://www.pressreader.com/india/the-hindu/20170617/281960312742363

A quote from the article: "So in a nutshell: R1a [DNA ID] is distributed all over Europe, Central Asia and South Asia; its sub-group Z282 is distributed only in Europe while another subgroup Z93 is distributed only in parts of Central Asia and South Asia; and three major subgroups of Z93 are distributed only in India, Pakistan, Afghanistan and the Himalayas. This clear picture of the distribution of R1a has finally put paid to an earlier hypothesis that this haplogroup perhaps originated in India and then spread outwards."
