Is there actually any part of any country that is entirely genetically separate?

[Sikeliot]

What I mean is we often hear of romanticized tales of specific regions of countries, islands, etc. being entirely separate, usually being the result of some area having avoided conquest. I have spent much time searching for them myself.

Examples are:

1. Western Ireland supposedly being separate from the rest of Ireland genetically and being Iberian-like or at least, "pure" Irish
2. Southwestern England and Wales having no Saxon input and being Iberian-like or "pure" British
3. Parts of remote Sicily or Crete being "pure" Doric Greek or "pure" Middle Eastern or "pure" Italo-Celtic or whatever
4. Some part of Iberia having almost no Moorish DNA (this does exist in Basques, but otherwise, not really)

Does such a thing even exist?

I have come to conclude that the majority of European genetic structures have been in place for thousands of years well before any conquests or settlements we'd know of, and that demographic changes were wide-reaching and rarely skipped over any areas.

If you check Esko et al 2012 you will find out there are some villages in Italy which are so drifted that they have closer FST distance to Finns than they have to each other.

These are North European shifted isolates autosomally?

No I meant that they are very extreme genetic isolates.

Bottlenecked and inbred most likely. The Griko in Calabria are an example.

Not necessarily inbred. There is a bit of misunderstanding on this

The observed level of genetic isolation in Friuli-Venezia Giulia region is more extreme according to several measures of isolation compared with Sardinians, French Basques and northern Finns, thus proving the status of an isolate.

According to Fst distances Italians from Resia are genetically closer to Finns than they are to Italians from Sauris.

Likewise Italians from Sauris are genetically closer to Finns than to Italians from Resia. According to Fst.

This is exactly why I have a little laff to folk who take Fst seriously.

If I remember correctly the people of Val Resia speak a Slovenian dialect, so they are technically Slovenians, they form a little community within the borders of Friuli, linguistically and culturally separated from the rest of the region.

Sardinians, maybe.

They are more or less ethnically Slovenians (and bottlenecked), not very surprising, since Slovenians are closer to Finns than to other more regular N.Italians.



SMC are like that as well, maybe more half IT/SI and without the founder effect i think.
