[6] The population of the Srubnaya culture was among the first truly nomadic pastoralist groups, who themselves emerged in the Central Asian and Siberian steppes during the 9th century BC as a result of the cold and dry climate then prevailing in these regions.
[7] During the 9th to 8th centuries BC, a significant movement of the nomadic peoples of the Eurasian Steppe started when another nomadic Iranic tribe closely related to the Scythians from eastern Central Asia, either the Massagetae[8] or the Issedones,[9] migrated westwards, forcing the early Scythians to the west across the Araxes river.
[16] Archaeologically, the westwards migration of the Early Scythians from Central Asia into the Caspian Steppe constituted the latest of the two to three waves of expansion of the Srubnaya culture to the west of the Volga.
[32][31] The ancient Greek author Herodotus of Halicarnassus described the Androphagi as wearing Scythian-type clothing, and speaking a "peculiar language.
The Sula group of the Scythian culture which corresponded to the Androphagi was part of an area of Iranic toponymy and hydronymy.
However, traces of similar ritual cannibalism are recorded from seven earthworks of the Melanchlaeni and Budini, as well as in the Smiela kurgan 15, which was one of the earliest burials of the Tiasmyn group of the Scythian culture.
[30] Trade relations between the Androphagi and the ancient Greek colonies on the northern shores of the Black Sea had been established in the 6th century BC.
