"Erdosy (1995a), who is prepared to find "some support" for small-scale migrations associated with the intrusive BMAC elements noted earlier, nonetheless states: "Several cultural traits with good Vedic and Avestan parallels have been found widely distributed between the southern Urals, Central Asia and the Indo-Iranian borderlands. However, even allowing for the uncertain chronology of Central Asian sites, few of these traits show the northwest-southeast gradient in chronology predicted by our linguistic models." Rather, in the manner of other traits commonly associated with the "Aryans" within South Asia, "they originate in different places at different times and circulate widely, undoubtedly through the extensive interaction networks built up in the mid-3rd to early 2nd millennia B.C." The main point is that "it is impossible, thus, to regard the widespread distribution of certain beliefs and rituals, which came to be adopted by Indo-Iranian speakers, as evidence of population movements" (12)."
