What is your theory exactly? Who indo-Europeanized Yamnaya? Indo-European language coming from their CHG heritage rather than their EHG side doesn’t make sense because their Y-DNA remained EHG and they were very patriarchal so them adopting CHG or any other language is almost 0 percent because their elite would have to have Y-DNA of the people who indo-Europenized them. Sredny Stog having an admixture of 20 percent EEF is the first sign of contact between WSH and Globular Amphora.
