Slavic Chronology

[parastais]

So, G25 was built also to capture so called “Baltoslavic” drift. As a result 2 persons (Slavic and Germanic) might have same EEF-WHG-Yamnaya ratios, but they would plot very differently due to Slavic person having that drift.
Now we can find all Baltoslavic populations somewhere on axis from ~Balkans (HRV_IA or Hun_Late_Sarmatian, etc) to ~Baltics (LVA_BA). I wonder if it is at all theoretically possible to find out specifically “Slavic” drift?
So that modern Lithuanians that got a certain Baltic/Balkan ratio would plot different to ancient Slavic samples with same Baltic/Balkan ratio. According to most linguists Slavic split from Baltic before 1000 BCE and even if both languages stayed close and conservative up to AD, they would still have over 1000 years to develop their own micro-drift that might be unnoticeable in G25 which covers for whole Europe, but might be noticeable for some specifically built intra Baltic vs Slavic calculator.

maybe it could be detected using some more fine grained methods, like IBD sharing and chromosome painting.

this could be how Slavs looked like before absorbing the remnants of Chernyakhiv, Goths etc.

Sorry if this has been discussed a lot already, but are you implying that Slavs today (Including West and South Slavs) have Gothic-admix?

I'm not sure this was discussed much.
I explored mostly the ancient Slavic samples, which are mostly from ~1000 AD or so, and they are certainly modelled well with Chernyakhiv and Wielbark:



and these samples are very similar to modern Slavs, so they should have it too.

Whilst I agree with spirit of the post.
Bodzia guys might have had some Scandinavian admixture. I think they were Viking time burials, culturally Viking. Maybe someone can correct me if I’m wrong.

[Strider99]

Yes, from page 50 of the supplementary information of Population genomics of the Viking world:

"Equally unique were the rich grave goods, which may be linked mainly with Scandinavia and Kievan
Rus’, but also with southern and western Europe"

"Analyses of strontium isotopes and aDNA have indicated that a part of the population buried at Bodzia was not local, but was probably of Scandinavian and/or Rus-Varangian origin. A special role is played here by the tomb of a young warrior (E864/I) buried together with three young women; one of them was placed below him, in what is a two-level burial pit. In his tomb, a ceremonial sword was folded, ornamented in the Mammen style. On the strap-end there is a bident – the tamga of Prince Sviatopolk the Accursed (1015-1019 CE), who was the son of Vladimir the Great and husband of a daughter of Polish king Boleslav I (the Brave)."

E864/I is sample VK157.

they are from the Viking study, I'm not sure about the exact burial context.

As far as G25 is concerned they might as well be a mix of Slavs and Goths.
testing Viking ancestry is much harder because the Swedish and Danish Viking samples range from Finnish to French-like and beyond.

And they look ancestral to modern northern Poles, they are similar to the modern Polish_Kashubian in G25.

I do not know why this belief that early Slavs should have maximally much of the Balto-Slavic WHG? Today the Balts and the Eastern Slavs have the most of this WHG. Today's Balts moved away genetically from the Balts of the Bronze Age in the direction of the Western Slavs. In turn, the Eastern Slavs are genetically away from the Balts in the direction of the Western Slavs. So the early Slavs should look genetically rather like the West Slavs. The more that among the early Slavic samples individuals with West Slavic genetics predominate. We also officially know that the early Slavs from Poland will be genetically West Slavic.

[bce]

Today the Balts and the Eastern Slavs have the most of this WHG.

that's because they have Baltic and Finnic ancestry.
medieval east Slavs were slightly balkan-shifted and similar to some more southern Ukrainian groups.
