Balto-Slavic drift evolution : PCA

[leonardo]

After I made this PCA based on ancient north-Eurasian samples it is obvious that Balto-Slavic drift has HG source (the colours are according to the age of the sample, the pink are the youngest, the yellow are the oldest, orange -> yellow ->green ->blue ->pink ->red):



I made a new HG-BS profile extracting EEF ancestry from my last HG-EEF BSD profile.
Such profile on PCA falls exactly inside the Baltic HG cluster:

Code:

HGBSD,0.144719,0.116557,0.193513,0.209265,0.122825,0.072783,0.020628,0.042548,0.045505,-0.046339,-0.004144,-0.033363,0.059545,0.062023,-0.004989,0.016938,-0.007928,0.011088,-0.003257,0.027140,0.042204,-0.000779,-0.017460,-0.116768,0.011782,10,1666,bold,1

for all ancient samples is (the samples with HGBSD drift have blue circles proportional to HGBSD drift):



only older than 1800 BC (maximum BSD is 52% - Vatya_o):



older than 2600 BC (magnified because maximum HGBSD is 25%: NEO527, NEO551, Donkalnis7, NEO302, NEO508, Kretuonas5, Tamula1, I4110):



Modern HG-BSD distribution (the maximum is Latvian 33%) :



Every image can be opened in a new tab and magnified.

Seems as if the oldest samples fall into three camps. Would you think the epicenter is in what is now Ukraine and the earliest samples went north and south, respectively?
