"Like all other archaeological cultures, there is no unanimity concerning the Indo- Iranian or Indo-Aryan ethnic identification of these burials either. Lyonnet wonders why, if they had been Indo-Aryans who had provoked or appeared at the time of the collapse of the Bactria and Margiana Archaeological Complex (BMAC), Namazga, and Harappan civilizations, they did not continue to foster the links between these regions, which had previously been connected for millennia. Rather, these connections collapse at this time (Lyonnet 1993, 83). She underscores the extreme paucity of metal objects found in the graves, which "is rather odd for a culture considered to come from the Andronovo people, famous for their metallurgy" (Lyonnet 1994a, 430). Moreover, "no trace of the horse is found, there is no evidence of any social differentiation, and, altogether, the material is rather poor" (430). As far as she is concerned, "if we are dealing with intruders, as some features suggest, and if it is certain that they are not Andronovians, we do not have enough evidence to identify them as Indo-Aryans. We can only compare their movement to the textually known much later migrations of two other groups, who, coming from 'the steppes,' went through Central Asia into India." These are the Kusanas around the beginning of our era, and the White Huns in the fifth century A.D.: "All these nomads, albeit at different periods, took exactly the same path, used exactly the same areas for their cemeteries consisting of kurgans that all look alike from the outside" (430)."
