Why do people separate Germanic and Celtic peoples if they are almost identical genetically?

[Bogdan]

Most have separate culture and language.

Distinguishing Balts from Slavs is also very easy, except for borderland areas (like North-East Poland vs. South-West Lithuania).



Because some GEDmatch calculators suck.

what about that image? it's incorrect then?

[Peterski]

True, even in calculators who have seperate Celtic and Germanic components like in Eurogenes K36 NW Euros overlap heavily.

I've seen Irish people who score a lot (like 20%) of Norway or Netherlands, but they still score mostly Ireland.

It is not difficult to tell apart someone from Ireland or Cornwall and someone from Germanic countries.

It is much harder with South-Eastern English people though. They are more Germanic-influenced.

[Peterski]

people talk about celtic and germanic as if they was different ethnic groups apart nationalities

they have a similar genetic cluster in genetics tests

what about that image? it's incorrect then?

All these PCA graphs show is that entire Europe is a smooth genetic continuum, except for some outliers like Finland, Sardinia or Basques.

I don't see how you managed to conclude based on these graphs that Celts and Germanics together form a "separate race".

You can tell apart North Germans from Scandinavians in K36 aswell cause of the Fennoscandia component, so it's not just between Celts and Germanics.
But there are still many Swedes, Danes, Dutch etc who can score over 20% North Atlantic on K36, higher than many Irish or Welsh people.
However in lower K calculators like Eurogenes K13/K15 it's a lot harder, almost impossible. Atleast between non-Scandinavian Germanics and British Celts. But on the other hand Germanics and Slavs are very distinguished already with these low K calculators.

not a "separate race", more like a macro ethnic group

like Northwest(Celtic/Germanic), Northeast(Slavic/Baltic),Southwest(Iberian/Sardinian/Southern French) and Southeast(Italian/Balkans)

Average person in UK:

36.94% British (Anglo Saxon)
21.59% Irish (Celtic)
19.91% Western European (France/Germany)



The most British people in England are found in Yorkshire (41.17% Anglo Saxon)
The most Scandinavian people in England are in the East Midlands (10.37% Scandinavia)
The most Western European people in England are in the East of England (22.52% France/Germany)

Modern British is not Anglo-Saxon. We have Fresh-Off-The-Boat Anglo-Saxon genomes (ancient DNA) and they were not so similar to modern English people at all, because they later mixed with Celts and that's how modern English were "created".

Original Anglo-Saxons are going to get Danish or Dutch, no matter which calculator you use.

Neither are modern Irish 100% Celtic, many have significant Norwegian or English admixture.

Roman Era, Celtic gladiator, highest similarity to modern Irish and Bretons, much lower to Germanic groups:

There's like a 10 point difference for everywhere except eastern Germany

[Peterski]

The problem with statements such as "Celts are similar to Germanics" made based on modern populations, is that there are probably no pure Celts left today. All the "Celtic" populations today are mixed with something else. Even the Irish have some Germanic ancestry in addition to Celtic.

So claiming things about Celtic DNA based on modern populations is like claiming things about Spanish DNA based on Latin Americans.
