Posts about 23andMe
Perhaps ignore isn’t the right word, but, what i am trying to say is, that 23andme doesn’t seem to be working on breaking down the “eastern european” category into smaller groups.
I don’t understand why, all the other groups are broken down into smaller groups, yet 23andme calls everyone from Hungarians to Latvians “Eastern European”, even though there are definitely a few distinct separate clusters in Eastern Europe.
China was broken down into a few different groups, i believe it is time to do the same for Eastern Europe.
Below i will copy paste text from an old post of mine, giving a few suggestions, remember, these are just my thoughts, i am not claiming they’re the only correct possibility for this, if you disagree, feel free to let me know in the comments.
Finland becomes part of the Eastern European group, Finland is not in the northwest of the European continent and finns are not genetically close to Northwestern European people.
1st group: Southern/Western Russian, Belarusian and Eastern Ukrainian: People from these regions are extremely close to each other, they are all relatively pure Slavic populations and share pretty much the same ancestry, so much so that many times i've seen individuals on gedmatch or another calculator plotting with another region's average (for example a Russian scoring Belarusian as first population)
2nd group: Czech, Slovak, Slovene, Hungarian and Western Ukrainian: These are majority Slavic groups with significant non-Slavic ancestry, they all plot close to each other and can have significant overlap, i think it makes sense to group them together.
3rd group: Lithuanian and Latvian: They are pretty close to each other genetically, both Baltic people, both are almost purely Northeastern European
4th group: Finnish and Northern Russian: Both are of similar origins, they seem to be majority Eastern European populations with somewhat significant Siberian admixture, despite the fact that northern Russians speak a Slavic language they often plot close to Finns, this is because much of Northern Russia was originally Finnic speaking.
Groups i don't know how to categorize: Estonians: They have some Siberian admix but not as much as Finns and many Northern Russians, they are somewhere in between Balts and Finns, they could be grouped with either i guess.
Poles: Ok, this one is pretty tricky, apparently Poland has a lot of variety, looking at gedmatch averages it would seem like the Northeast of Poland is close to East Slavs while the South is soemwhere in between East Slavs and Czechs/Slovaks, however, having seen many individual results of Poles i think the variety is not always regional and instead kinda random, i have seen results from northeaster Poland with a western shift and results from central Poland that clustered with Belarus, i have even seen some Czech like Western Poles who were not close to the Polish averages on most calculators, i really don't know how Poland should be categorized.
Ofc, this isn’t a perfect solution, since there is a good bit of overlap between these groups, for example, some Lithuanians are genetically closer to Belarusians than to Latvians, and vice versa, some Belarusians and Russians are genetically closer to Lithuanians than to Ukrainians, so such people would likely score a mix of “Baltic” and “Russian, Belarusian & Eastern Ukrainian”, i still think however that my suggestion is far better than what 23andme currently has.
