アナトリア語派
Damgaard and Wang state that the steppe-model is the dominant model, and does account for a steppe-origin of the Anatolian languages. Damgaard notes that "Among comparative linguists, a Balkan route for the introduction of Anatolian IE is generally considered more likely than a passage through the Caucasus, due, for example, to greater Anatolian IE presence and language diversity in the west." Kloekhorst argues that the Anatolian languages have preserved archaisms which are also found in proto-Uralic, providing strong evidence for a steppe-origin of PIE.
