“She holds that the dispersal of the Indo-European languages commenced from a region somewhere in the vicinity of ancient Bactria-Sogdiana, thus bringing the scenario closer to the Indian subcontinent, but not quite there.”

“The bifurcation of Indo-Iranian is well known to be evident not only in South Asia, where all three of Indic, Nuristani and Iranian sub-branches are found, but also in ancient eastern Anatolia, where either an Indie language or undifferentiated Indo-Aryan or Indo-Iranian is evident in early Mitannian vocabulary (e.g. aika-wartanna ‘one course’, where aika is cognate to Sanskrit eka ‘one’, an Indie word) while Old Persian and Avestan are Iranian...”

“A consequence of the reconstruction offered here is that the attested distribution of IE then turns out to be no singularity but just one regular episode in a standing pattern of spreads.”

“The Iranian family, which was next to sweep across the steppe and deserts, finds its region of greatest diversity in the central Asian mountains, and its ancestral Indo-Iranian family finds its own greatest diversity in the mountain region from central Asia to northern India (i.e. Bactria- Sogdiana and parts just south).”

“No migrations are required to derive the attested IE distribution from a reconstructed homeland consisting of a locus in western central Asia and a range over the steppe and desert. Sometime in the fourth to early third millennium, PIE spread along the steppe and southern trajectories to occupy the entire reconstructed range: the steppe, the desert of wester central Asia, part of the adjacent mountains, and perhaps some of south- west Asia. At this time its distribution was continuous, and that distribution had been achieved not by migration but by expansion.”

“These principles make it possible to pinpoint the locus in space more or less accurately even for a language family as old as IE. Here it will be shown that the locus accounting for the distribution of loanwords, internal innovations, and genetic diversity within IE could only have lain well to the east of the Caspian Sea.”
