attestation at the Andronovo site of Sintashta, Kuz'mina (1994) argues that the chariot corroborates the identification of Andronovo as Indo-Iranian. dated a chariot burial at Krivoye Lake to about 2000 BCE and a Bactria-Margiana burial that also contains a foal has recently been found, indicating further links with the steppes. Mallory acknowledges the difficulties of making a case for expansions from Andronovo to northern India, and that attempts to link the Indo-Aryans to such sites as the Beshkent and Vakhsh cultures "only gets the Indo-Iranian to Central Asia, but not as far as the seats of the Medes, Persians or Indo-Aryans". He has developed the "kulturkugel" model that has the Indo-Iranians taking over Bactria-Margiana cultural traits but preserving their language and religion while moving into Iran and India. Fred Hiebert also agrees that an expansion of the BMAC into Iran and the margin of the Indus Valley is "the best candidate for an archaeological correlate of the introduction of Indo-Iranian speakers to Iran and South Asia." According to Narasimhan et al. (2018), the expansion of the Andronovo culture towards the BMAC took place via the Inner Asia Mountain Corridor. Bactria-Margiana culture The Bactria-Margiana Culture, also called "Bactria-Margiana Archaeological Complex", was a non-Indo-European culture which influenced the Indo-Iranians. It was centered in what is nowadays northwestern Afghanistan and southern Turkmenistan. Proto-Indo-Iranian arose due to this influence. The Indo-Iranians also borrowed their distinctive religious beliefs and practices from this culture. According to Anthony, the Old Indic religion probably emerged among Indo-European immigrants in the contact zone between the Zeravshan River (present-day Uzbekistan) and (present-day) Iran. It was "a syncretic mixture of old Central Asian and new Indo-European elements", which borrowed "distinctive religious beliefs and practices" from the Bactria–Margiana culture. At least 383 non-Indo-European words were borrowed from this culture, including the god Indra and the ritual drink Soma. The characteristically Bactria-Margiana (southern Turkmenistan/northern Afghanistan) artifacts found at burials in Mehrgarh and Balochistan are explained by a movement of peoples from Central Asia to the south. The Indo-Aryan tribes may have been present in the area of the BMAC from 1700 BCE at the latest (incidentally corresponding with the decline of that culture). From the BMAC, the Indo-Aryans moved into the Indian subcontinent. According to Bryant, the Bactria-Margiana material inventory of the Mehrgarh and Baluchistan burials is "evidence of an archaeological intrusion into the subcontinent from Central Asia during the commonly accepted time
