“Federovo monuments are discovered not only in the Urals but also in the south of Central Asia and Afghanistan, where Ugrians have never lived.” (p.201) Moreover, elsewhere she designates central Kazakhstan as the Fedorovo heartland: “The further one moves from central Kazakhstan, the frequency of the complex diminishes and substratum elements increase”. (p.24)

«the variety of Andronovo funeral rites finds a complete and thorough correlation in early indic texts ». (p.195)... These “hearths comprise a shallow round or oval pit… often covered with flat stone slabs on the bottom…. This hearth is described in ancient Indian texts as the domestic fire gārhapatya-, ‘fire of the master of the house’… Such hearths were used for ritual purposes: a bride would go around it, a widow would perform a ritual dance, people jumped over it during a feast.” (p.45)... [Another type of hearth] “has a rectangular form… and was made of closely adjusted rectangular stone slabs inserted into the ground on their narrow ends. Such hearths were found in the centre of a house, kept clean, and it is likely that they had a ritual function… This type of hearth corresponded to the early Indian special cult hearth āhavanīya…” (p.45)

A migration that is identified, however, is east-to-west: “a part of the Timber-grave tribes moved [from Uzbekistan or even the Amu Darya basin] to the North Caucasus because of the crisis; they had already begun appearing and settling in the Caucasus at an earlier time”. (p.454) [This must be the Scythian migration, which only added to the already existing Iranian presence near and beyond the Urals. Intermittently, groups of Iranians must have moved from Bactria to the Urals and even to Ukraine for more than a thousand years. (One of the later migrating tribes were apparently the Hrvat, now known as the Croats. Before migrating west and adopting the Slavic language of the Serbs, they belonged to the Harahvaita tribe in Afghanistan mentioned as tribute-payers to the Persian empire in an Achaemenid document.)]
