What lead to the resurgence of WHG ancestry and Y-dna in Neolithic Europe?

[Finn]

Ertebølle in particular was one of the forager strongholds, typically most forager strongholds were close to the sea or big rivers, like Ertebølle, Lower Don and Yellow River people. They had the demographic strength and cultural practises which made them more resilient and allowed them to adopt Neolithic innovations on their own terms. There can be little doubt that Ertebølle contributed significantly to TRB and GAC.

Yes and the range is differentiated TRB Sweden and Poland have had significant more EEF.

There are Polish individuals that look like Blatterhole.

TRB-F is from Ostorf Mecklenburg Germany, pretty much in the PWC (/ Ertebølle) corner (Pol TRB in the EEF corner).

It looks like these WHG-rich farmers around the Dutch-German-Belgian border area are not that important for modern day NW Europeans. The Swedish farmers with much lower WHG-levels are preferred.

Generally yes, but the North Dutch are a touch different:

OHW! you took the scaled one....I guess mom and I are pretty off road then!!!

It may have just been diluted over time. It was definitely important into the Beaker period and beyond. Here's some F3 outgroup affinities to Iron_Gates_HG
Steppe_EBA average ('pure' Yamnaya, Afanasievo, Poltavka, Catacomb): 0.2777
England_N: 0.2861
Scotland_Isbister_N: 0.2862
Poland_GAC: 0.2864
And those are some of the higher WHG populations of Europe at the time.

England_BellBeaker: 0.2861
Netherlands_Oostwoud_BellBeaker: 0.2873
Scotland_BellBeaker: 0.2858

They are matching that high-level of WHG affinity even despite their 50-55% Steppe ancestry. Let's subtract say 50% from England and Scotland beaker and 55% from Netherlands and you get their EEF half looking like...
England: 0.2945
Scotland: 0.2939
Netherlands: 0.2990

Germany_Blatterhohle_MN: 0.3143

Absolutely in your opinion, the Neolithic GAC also has an important genetic input from hunters and gatherers (WHG) as in the example of the people (family members) from the mass grave of Koszyce in Poland (30% WHG and 70% EEF), with TRB even 40% - 50% of WHG. Or the Narva culture in the Baltic States that lasted until the Bronze Age! (70% WHG and 30% EHG)

Indeed. In this context the Tollensee valley samples come to mind. They are Late Bronze Age and some of them harbored very high levels of WHG ancestry IIRC. I wonder what could be the source of that level of HG.
