Here's a dumb question

[Norfern-Ostrobothnian]

WHG definitely has Gravettian ancestry. I think they are about 30 % Gravettian, half whatever West Eurasian is in Dzudzuana without its Basal Eurasian ancestry, and a variable amount of ANE that depends per sample. Some minor Fournoul ancestry too but very very minor amounts and only really exists in Iberian hunter gatherers and not in what EHG gained.
