centuries in or near modern-day Romania, which was Dacian territory. He suggests that Romanian is a fully Romanised Dacian language, whereas Albanian is only partly so. Albanian and Eastern Romance also share grammatical features (see Balkan language union) and phonological features, such as the common phonemes or the rhotacism of "n". This theory however has been challenged and dismantled by other scholars. While Noel Malcolm suggests Romanian and Aromanian originated in the Southern Balkans from Romanized Illyrians Apart from the linguistic theory that Albanian is more akin to East Balkan Romance (i.e. Dacian substrate) than West Balkan Romance (i.e. Illyrian/Dalmatian substrate), Georgiev also notes that marine words in Albanian are borrowed from other languages, suggesting that Albanians were not originally a coastal people. According to Georgiev the scarcity of Greek loan words also supports a Dacian theory – if Albanians originated in the region of Illyria there would surely be a heavy Greek influence. According to historian John Van Antwerp Fine, who does define "Albanians" in his glossary as "an Indo-European people, probably descended from the ancient Illyrians", nevertheless states that "these are serious (non-chauvinistic) arguments that cannot be summarily dismissed." Romanian scholars Vatasescu and Mihaescu, using lexical analysis of Albanian, have concluded that Albanian was also heavily influenced by an extinct Romance language that was distinct from both Romanian and Dalmatian. Because the Latin words common to only Romanian and Albanian are significantly less than those that are common to only Albanian and Western Romance, Mihaescu argues that Albanian evolved in a region with much greater contact to Western Romance regions than to Romanian-speaking regions, and located this region in present-day Albania, Kosovo and Western North Macedonia, spanning east to Bitola and Pristina. An argument against a Thracian origin (which does not apply to Dacian) is that most Thracian territory was on the Greek half of the Jireček Line, aside from varied Thracian populations stretching from Thrace into Albania, passing through Paionia and Dardania and up into Moesia; it is considered that most Thracians were Hellenized in Thrace (v. Hoddinott) and Macedonia. The Dacian theory could also be consistent with the known patterns of barbarian incursions. Although there is no documentation of an Albanian migration, "during the fourth to sixth centuries the Rumanian region was heavily affected by large-scale invasion of Goths and Slavs, and the Morava valley (in Serbia) was a possible main invasion route and the site
