A rather bizarre map I found online. See
https://pastebin.com/ELK9qULK for an explanation of the place-names: "A lot of imagination has been used in some cases! Many nations are in different positions here and the actual timeline, and some etymologies can be a bit far-fetched..."
The caption asks "What if" the Indo-Europeans never left their original homeland and didn't displace Paleo-Eurasian, Uralic, and Turkic peoples. I don't know to what extent that is meant seriously and to what extent it is a deliberate tongue-in-cheek DBWI.
The obvious problem with the map and caption (if taken seriously for a minute) is that while some peoples like the Basques and Etruscans and the Finnish peoples may have been indigenous to Europe, to a large extent this map can be called "Map of Europe if it were inhabited by non-Indo-European peoples, many of whom are indigenous to Asia and would probably never have come to Europe if not for the Indo-European peoples already living there." The Magyars, Bulgars, Turks, Tatars, etc. on this map are obviously not in their ancestral homeland. And southern Ukraine, far from being a place where Indo-Europeans displaced Tatars, is widely regarded as part of the original Indo-European homeland...
Some of the place names, incidentally, seem to be based on the notion that "old European" river names are of pre-Indo-European origin--a notion expounded by Theo Vernnemann
https://en.wikipedia.org/wiki/Theo_Vennemann but rejected by the great majority of scholars.

Note also that the Inuit have colonized Iceland...
I can see the case that this belongs in ASB, but there are *some* real possibilities here.
