Davidski quotes:

"So there are no other options, unless Iranian languages were spoken by BMAC people before steppe incursions into Central Asia, and Steppe_MLBA spoke some unknown language that was also spoken in Europe.

But this isn't plausible for a number of reasons, including the fact that there's no direct, unambiguous link between BMAC and European Indo-Europeans, except of course Steppe_MLBA, which influences BMAC at its tail end."



So its either that Mycenaeans didn't speak greek or Srubnayas didn't speak Indo-iranian

He isn't saying that Srubnaya was the source for these two languages, but a population genetically similar to Srubnaya (An R1a Steppe_MLBA population). Though interestingly, considering R1a is generally associated with Indo-Iranian and Balto-Slavic peoples and we have 2 satem language branches being spoken in the Balkans during the Iron Age (Dacian and Thracian), and there is a Srubnaya-like R1a-Z93 elite in late Bronze Age Bulgaria, who was probably a recent migrant. Perhaps Srubnaya was the source of the Daco-Thracian languages?

That being said I don't believe Srubnaya-like/R1a Steppe_MLBA-like population is the source of Mycenaean steppe ancestry and the Greek language. The Eastern Balkan extension of Yamnaya (Yamnaya_Bulgaria) is the most plausible imo, this intrusion is a lot earlier than Steppe_MLBA dating back to the late 4th Millennium and 3rd Millennium BC, which fits in with most estimations by linguists for the evolution of Proto-Greek. In nMonte modelling, which Dave actually showed on an earlier post actually, Mycenaeans prefer Bulgarian Yamnaya over the Srubnaya-like R1a-Z93 late Bronze Age balkanite elite as a source of steppe ancestry (http://eurogenes.blogspot.com/2018/03/main-candidates-for-precursors-of-proto.html). Additionally, R1a-Z93 in modern Greece is almost absent, there are more sensible steppe lineages such as L23 (Yamnaya lineage) or even I2a2 (like the clade found in Bulgarian Yamnaya) which appear at non-trace frequencies, and of course far higher than the virtually non-existent presence of Z93. So I'm placing my bets on the Yamnaya intrusion into the balkans as the source of the Proto-Greek language and them being mainly R1b with some I2a2.
