A Georgian (100% Caucasus ancestry) plots much closer to Northern Europeans on global PCA than someone who is 90% Northern European + 10% Japanese. The 10% East Asian admixture creates a far larger displacement along the primary Europe–East Asia axis than the relatively modest West Eurasian shift that separates Georgians from Northern Europeans.
This kinda of surprises me and kind of does not.
Obviousely we are closer related to Georgians than we are to Japanese and obviousely mixing does take place, naturally, at borders.
The mixing that is not natural is the one where humans travel hundreds and thousand of miles to fuck around and find out.
I think that there is also another problem that many ignore or fail to notice and that is the fact that we are all rooted to our homelands, if our ancestors have lifted there for several generations and adapted to them.
What I mean by that is the specific climate, the chemical composition of the soil, which affects the fruits and vegetables as well as animals and of course the air, air pressure etc. .
I have noticed that my body reacts negatively when I travel and drink different water and eat foreign food, even though it is the same food that I would eat at home, except that it's origin is different / too foreign.
I know for a fact that negroes and even southern Europeans have a hard time living in Germany and other northern regions because of the lack of sunlight resulting in Vitamin D defficiency.
Blacks in Europe absolutely have to supplement Vitamin D. Even Turks, Arabs etc. have to do it.
This part of the world is simply not healthy for them, whereas we would overall benefit from moving further south, because then we'd have an abundance of sunlight.
When I retire I will most likely move to Croatia to spend my last days there.
I might also move to Japan because of the nice winters there.
They have some beautiful and cozy little villages in the countryside, where it snows a lot. It is so picturesque.
But I will probably just stick to Croatia.
