In short, apart from the time-space expectations, there is nothing in the archaeological material that could be taken as tags for tracing the Indo-Ir… - Henri-Paul Francfort

Francfort (1989) stresses this point: "Nothing allows us to dismiss the possibility that the Andronovians of Tazabagjab are the Indo-Iranians as much as the fact that they vanish on the fringes of sedentary Central Asia and do not appear as the ephemeral invaders of India at the feet of the Hindu Kush" (453).

Consequently, in current migratory hypotheses, in the same way that the Oxus Civilization disappears upon contact with India, the culture of the Andronovo steppes vanishes upon contact with the Oxus Civilization and never crosses towards the south the line which extends from Kopet Dagh to Pamir-Karakorum, which poses serious problems for historically translating the Indo-Aryans towards the South.
