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

[Peterski]

Ancient Celtic samples in Eurogenes K36 (the darker color = the higher similarity to modern populations):

Hinxton1 (Iron Age Celtic Briton 160 BC - 26 AD):



Hinxton4 (Iron Age Celtic Briton 170 BC - 80 AD):

For comparison here is a Germanic sample:

RISE174 (Early Medieval Sweden, 427-611 AD):

Who is separating them and how?

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

they have a similar genetic cluster in genetics tests

[Peterski]

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

[AphroditeWorshiper]

I'm just saying that I have no problem telling apart for example Irish or Breton ancestry from Germanic, that's it.

If you have a problem with the fact that there is no problem telling them apart, then it is your problem not mine.

In terms of haplogroups they are also different.

b... but

even haplogroups they are similar, they are basically R1b(Y) and H(Mt)

with sweden a little bit more est with I1, N1c and R1a. and maybe East Germany?

Modern Brits are a Celto-Germanic racial mix, that's why you can see some British samples plotting closer to Germanic populations.

However, the most Celtic British people plot far away from Germanic populations - on the western (right) end of this graph.

If you take British genomes from 100 AD or from 400 AD - before Germanic invasions - the difference will be even more clear-cut.

don't is a veryyyy far and different, common

like Balts and Slavs who are similar genetically, but different groups

[Peterski]

It is just like modern Mexicans, some will plot closer to Spain and some very far away from Spain.

Same with modern British people - some are more Germanic-admixed, others are still very Celtic.

let's tell that Irish and Breton are the "most" Celtic nowadays group


I see some Gedmatch results here that they get very closer to Dutch,German and Danish

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.

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