Are components like WHG, EEF, Steppe, Iberomarusian, Natufian basal?

[Johnson Reed]

i.e. are they unique components that aren't just a mix of other previous populations the way modern Europeans are a mix of WHG, EEF, and Steppe?

[Russki]

Steppe = 45-65% EHG + 25-45% CHG + 5-15% EEF
EHG = 70% ANE + 30% WHG
CHG = 70% Ganj Dareh + 20% AHG/ANF-like + 10% ANE
EEF = 89-93% ANF + 7-11% WHG
Iberomaurusian = 63.5% Natufian-like + 36.5% modern SSA-like (Yoruba-like and Hadza-like)

Fragmenting WHG, ANE, ANF, Ganj Dareh and Natufian produces wonky results even in qpAdm but here are some takes:

WHG (Western Hunter-Gatherer)
Early WHG = Villabruna
Ancestors of the Villabruna cluster arrived from the Middle East in Late Upper Paleolithic (LUP).
Later WHG (North of the Alps): Villabruna WHG + lineages closely related to Goyet-Q2
Oberkassel WHG: 75% Villabruna WHG + 25% Goyet-Q2
Pre-WHG Initial Upper Paleolithic (IUP) humans are the earliest out-of-Africa Homo Sapiens in Eurasia. They carried high levels of Neanderthal admixture.
All WHG North of the Alps are a hybridization of the original Villabruna WHG and these earlier populations.

Ganj Dareh
Ganj Dareh = 52-62% ANE + 38-48% unknown lineage, presumably Basal-related or Basal-descended
ANE (Ancient North Eurasian)
ANE = 73-84% unknown West Eurasian lineage distantly related to Kostenki14 + 16-27% unknown East Eurasian lineage distantly related to Tianyuan
ANF (Anatolian Neolithic Farmer)
ANF is directly descended from AHG (Anatolian Hunter-Gatherer).
AHG = 50% WHG + 50% unknown Natufian-like lineage
Natufian
Vallini et al. (2024) modeled the amount of Basal Eurasian ancestry among Natufians at roughly 15%, with the remainder being associated with West Eurasian sources.
Daniel Shriner (2018), using modern populations as a reference, found 28% autosomal African ancestry in Natufian samples, with 21.2% related to North Africa and 6.8% related to Omotic-speaking populations in southern Ethiopia, which reveals a plausible source for haplogroup E in Natufians. The remaining 61.2% of ancestry is related to Arabs and 10.8% is related to West Asians.

Steppe = 45-65% EHG + 25-45% CHG + 5-15% EEF
EHG = 70% ANE + 30% WHG
CHG = 90% Ganj Dareh + 10% ANE
EEF = 89-93% ANF + 7-11% WHG
Iberomaurusian = 63.5% Natufian-like + 36.5% modern SSA-like (Yoruba-like and Hadza-like)

So it seems like, of the European components, WHG is the most basal of them, in that it is mostly basal Villabruna European with about 1/4 of some extinct ghost population.

I wonder why Europeans are usually modeled as WHG/Steppe/EEF if those aren't the most basal components, though.
