While we experience heat in Finland and people spend time in air-conditioned rooms and the secrecy keeps going on as to the Finnish Iron Age samples (which we know being analysed), I started to think what can I do. Something definitely. I can look if there is any continuation from the Baltic Bronze Age to modern populations through the Iron Age Estonia. We remember studies finding out that the Iron Age Estonia met a migration holding male haplogroup N1c. This observation keeps inside the idea of a larger migration of N1c to Latvia, Lithuania and Finland. I also picked Estonian Medieval samples carrying this particular haplogroup to extend observations about possible replacement of Bronze Age Estonians by eastern newcomers. All right, in case my tests fail to see any replacement, it doesn't mean that any replacement didn't occur, it proves only that the migration didn't change the genetic profile of Bronze Age Estonians. So I did a dStat-test comparing whether I can see notable change between Bronze Age, Iron Age and medieval Estonians compared to present-day populations. If there is any shift to the present-day it would mean that there is a continuum from a dedicated migration. If there is no notable shift it would mean that no notable eastern or any kind of notable migration existed changing present-day populations through the Iron Age Estonia.
Looking at results and using the Swedes as a threshold my conclusion is that only Latvians and Estonians show in some extent drift towards the change in Iron Age Estonia. Only Latvians and Estonians show notable shift towards Medieval Estonia (again using the Swedes as a threshold), which sounds weird, because the common idea is that this shift should be strongest is Estonia and Finland, not in Latvia. The row mauri is my result made by an imputed genome I got from 23andMe. The imputation was done by a reputable US university.
Significant results are colored.
