Abstract: For hundreds of thousands of years, humans moved across the
“Southern Arc,” the area bridging Europe through Anatolia with west
Asia. Genetic data are relevant for understanding linguistic evolution
because they can identify movement-driven opportunities for language
spread, especially during the Chalcolithic and Bronze Ages about 7000 to
3000 years ago, when Indo-Europeans with various language dialects
began to migrate across the Eurasian Continent. Changing ancestral
landscape of the Southern Arc, as reflected in DNA, corresponds to the
structure inferred by linguistics, which links Hittite and Luwian to
Indo-European, especially Greek, Armenian, Latin, and Sanskrit
languages. All ancient Indo-European speakers can be traced back to the
Southern Arc, as the DNA of the Bronze Age people of the region shows.
There seems to be a definite link connecting the
Proto-Indo-European–speaking peoples with the speakers of the languages
in the Armenian highlands.
