Davidski at Eurogenes rightly pans, in a fifth installment of criticism, the recent Lazaridis, Alpaslan-Roodenberg et al. paper (that has lots of good new ancient DNA evidence from a critical area). The new paper wrongly interprets the data as supporting an Armenian or Anatolian origin of the Indo-European languages, when it is far more plausible that the Indo-European languages originate in Eastern Europe stating:
The debate over the location of the so called Indo-Anatolian homeland won't be decided by the persistence of any type of genetic ancestry in ancient Anatolia.It'll be decided by a multidisciplinary study on the interactions between the ancient peoples of the North Pontic steppe, the eastern Balkans, and western Anatolia. . . .
the authors should've given us a painstaking account of the spread of different ancient Indo-European speaking groups into Anatolia and explained how, overall, their DNA was rapidly diluted to a trace amount.However, instead they treated us to a make-believe tale about a so called Indo-Anatolian homeland in what is now Armenia.
Anatolian languages arose in Anatolia on a more elite dominance type model rather than a demic replacement model.
Also the linguistic based estimates of the Anatolian languages divergence from other Indo-European languages grossly underestimates the role of contact with a different and stronger substrate than in most of the other cases of the spread of the Indo-European languages.
