It's time to come up with something to fill the blog with again, so I thought I'd take a look at what Iron Age Northern Europe looks like in the light of the G25 coordinates. The first picture shows the result after removing the Iron Age samples from the region of the modern Russia and the second one shows the results of all samples.
A few observations:
- Iron Age samples found in Sweden spread genetically eastward over a wide area. The influence of the eastern shore of the Baltic Sea can be seen on the Swedish side and many samples look like Balts, but only one shows Asian (Saami) affinity, four in lesser amount.
- the deceased in the Viking graves found in Poland are related to some influence from the eastern side of Sweden. However, the deceased from the Polish Wielbark culture are quite Central European.
- there are still no samples of the ancient Finnish population from the Finnish region, so no one can say anything for sure about their genetic profile. All speculations about the relative influences of the Finno-Ugric, Germanic and Arctic populations are pointless until we have the ancient Finnish samples available.
- an ethnic profile is the sum of many factors. It involves heredity, language and culture. This test does not aim to present an ethnic profile, but only genetic differentiation by region. It is completely pointless to claim that a Swede is this way, a Finn is that and an Estonian is that. However, by choosing historical samples from the Iron Age and younger, the test provides a good continuity with the present day compared to using older antique samples.
- there is a lot of Asian heritage in the Russian Iron Age sample set, which should be visible in coordinates of the Finns
- Eurogenes G25 data is based on global PCA coordinates and the result does not correspond to the result based on regional differences. Thus, the result does not correspond to the result obtained based on regional-specific genome data. Regional-specific genome data does not take into account the effect of population connections outside the region, G25 data does. This is a secondary PCA based on G25-coordinates.

Readers, if you want to see your location on the map, plese send your scaled G25 coordinates to the gmail address kassu220977<at> and you will receive a picture in the return mail. I will keep the address active until the end of April and send the results at the beginning of May. I do not need your personal information, only email for the reply.
