"In Nichols's Bactrian homeland, Proto-Indo-European expands out of its locus, eventually forming two basic trajectories, appearing, on a language map, like two amoebic protuberances bulging out from a protoplasmic origin. The language range initially radiates westward, engulfing the whole area around the Aral Sea from the northern steppe to the Iranian plateau. Upon reaching the Caspian, one trajectory expands around the sea to the north and over the steppes of central Asia to the Black Sea, while the other flows around the southern perimeter and into Anatolia.27 Here we have a model of a continuous distribution of Proto-Indo-European—which has been defined as being, in reality, a dialectal continuum—covering a massive range from where the later historic languages can emerge, without postulating any migrations whatsoever. By the third or second millennium B.C.E. we have the protoforms of Italic, Celtic, and perhaps Germanic in the environs of central Europe (and presumably Balto-Slavic as well), and the protoforms of Greek, Illyrian, Anatolian, and Armenian stretching from northwest Mesopotamia to the southern Balkans (Nichols 1997,134). Proto-Indo-Aryan was spread- ing into the subcontinent proper, while proto-Tocharian remained close to the original homeland in the Northeast."
