We got back to Serednii Stih being PIA. What was the point of the CLV meme when Anatolians had Serednii Stih Y dna? I feel like we need a new study to see if any autosomal dna fits can be made with Serednii Stih. If so, then everything is simplified. IE is just a steppe language with anatolian being an early off shoot of it.
