Widzimy, że wczesnośredniowieczni Polacy wcale nie wyglądają genetycznie jakoś szczególnie wschodniosłowiańsko/bałtycko, jak nam to wróżyli Dawid z Michałem. Nie doszło też po wczesnym średniowieczu do jakiejś ich szczególnej westernizacji pod wpływem osadnictwa niemieckiego i holenderskiego, co zapowiadał Michał. Widzimy raczej sytuację odwrotną. W porównaniu z Polakami wczesnośredniowiecznymi, współcześni są ogólnie nieco bardziej przesunięci genetycznie w kierunku Słowian Wschodnich i Bałtów. Nie ma w tym jednak nic dziwnego, albowiem w późniejszych czasach doszło do asymilacji bałtyckich Prusów, Galindów i Jadźwingów i do utworzenia Unii Polsko-Litewskiej, a po drugiej wojnie światowej miały miejsce przesiedlenia kresów wschodnich.
As stated in the blog post it's from the "merged fastq files". Individually their coverage is too poor, but you can sample SNP frequencies from the whole population.

I only tested one sample. I'll run them all but it will take some time as there are 141 files in total.

I wrote in this topic:
David:
"They will eventually, and they'll probably cluster with/near East Slavs like the three that are already there".
David, somehow I don't see it! Perhaps apart from one, none of these samples goes beyond the scope of Polish genetic variation. These samples are not particularly East Slavic. Unless on some general level, because the Western Slavs actually cluster near the Eastern Slavs.
I need to check this one more time, but Krakauer Berg seems to be a quite mixed population with a possible Baltic(-like) intrusion.
And if true these samples indicate where such people may have come from:
KRA009 - https://www.yfull.com/mtree/H13a1a1e/
VK533 - 42.2% "Finnish-like", Öland, Viking Age - H13a1a1e, N1a1a1a1a1a1a
Any update on this?
