I find the idea that Basque would be particularly close to the FU culture to be completely ludicrous, though. The proto-culture basically never left the northern areas of Eurasia. That one splinter of it would somehow end up in the Pyrineans without a massive migration through (the populated) Europe is a huge, huge stretch.
How come there's a Georgia in the Caucasus and a Georgia in North America? Checkmate atheists
But in all seriousness a good example would be Turks in Anatolia and Turkic cultures in central asia disconnected from one another. Migrations that go through other culture groups is possible
While it's completely true that it's possible, the Turks aren't exactly cut of from the other Turkic peoples in the same way that the hypothetical FU-Basque would be cut off from the FU kern. The Turks are cut off from the Turkicore more in the way the Germanics on the Scandinavian peninsula is cut off from the Germanians in central Europe. A better example would have been the already FU Hungarians
But I retake my words of it being completely ludicrous. It's possible. It would just be very unlikely.
My personal guess is that Basque is related to ancient Iberian... there's not enough written of the latter to fully establish the similarity. But the numbers *are* practically the same. And the words I've seen seem kind of reminiscent. Not 100%, but rather vaguely reminiscent.
Do you mean the still-alive-by-Roman-times Iberians? I've always assumed they were IE, but now I realise I don't base that on anything but the assumption itself.

Let's not forget the third Georgia in the south Atlantic.
Oh and yo mama so fat she counts as a fourth Georgia
