Unless there is a mistake in the K=20 data, it means that all the WHG (like in Motala and La Brana) has now become extinct in modern Europeans (who are a mix of Yamna and EEF).
Exactly. However, all cultures *following* Corded Ware do show WHG admixture. The article even clearly states that a resurge happened. Also it states that modern Europeans could be explained as half Neolithic with a WHG resurge and half Yamnaya. So did that part of WHG go extinct in the Bronze or Iron age?
Even stranger is the fact that Swedish HG show no affinity *at all* to EHG nor to American Indians. However, we know some had quite some ANE admixture. But Loschbourg actually *does* have a tad EHG as well as a tad EEF. The latter would probably mean that a part of EEF actually is connected to Loschbourg. Let's assume that WHG contributed locally to the newly arrived farmers that would make sense. Stuttgart is far closer to Luxembourg than to North Spain or Sweden. It could even explain how Stuttgart got a part EHG. But where did the Caucasus part of Stuttgart come from?
There is a blogpost at Fennoscandia where it's explained that La Brana actually left quite some traces to Basques and Sardianians. Why doesn't that show up in K=20 here?

What is odd is that from K=16 to K=19 Yamna looks half EHG (deep blue) and half Caucasian-Gedrosian (greyish green), but in K=20 Yamna suddenly becomes 80% EHG (sometimes with some WHG) and only 20% Caucasian-Gedrosian.
Yes, a thing that also happens in the ADMIXTURE runs of the first Lazardis paper. That's why I wonder if I really understand how this works.
