"...The currently irresolvable contradictions that mar the many attempts made to reconcile the linguistic and archaeological evidence (and indeed biological anthropological evidence) for the “arrival of the Aryans in India” do not mean that the supposed “original Indo-European People” emerged in India (this would pose the same problems, but in reverse), nor do they mean that “invisible migrations” did not exist in the past. It simply means that, in the current state of knowledge, none of the hypotheses forwarded can be seriously demonstrated. Given the stakes involved, extreme caution needs to be exercised when attempting to solve this issue."
