Just stumbled upon this piece. This time from a Russian archaeolgoist.
M. Kelkar
"Catacomb and Pit-grave cultures have no genetic connection.
Timber-grave and Andronovo cultures have
no such connection with Catacomb culture too. Cultures of Scithian and
Sarmatian world were not forming on
the basis of the Late Bronze Age cultures placed from Dnieper river to
the Altai. So called "Andronovo culture"
is an archaeological myth. There are no features of "Steppe cultures"
in cultures of India and Iran. And there are
no Finno-Ugric borrowings in languages of Avesta and Rig Veda."
"CONCLUSION:
Let's sum up. As a result of my study, I (Grigoryev) worked out a new
historical model of origins and migrations of
Indo-European peoples, which I have tried to show in this article. The
conformity of my archaeological model to
the linguistic one, proposed by Gamkrelidze and Ivanov, permits to say
that Indo-European problem is solved,
but in general outline only. The detailed description of early
Indo-European history could done in some years, in
case of closely concerted actions of archaeologists and linguists."
