The site in Sweden was being worked thousands of years before the Norse people even arrived along the Southern Coast of Scandinavia. The site in Russia is in Keralia and that part of the world is well outside of any Bronze Age. Keralia was opened up to non-Sa'ami some time in the last 1500 years but some of the stone drawings there date back to 7500 BC, and possibly earlier. The important thing to remember is that when it was opened up they went immediately from the age of stone and bone to IRON!
One site on the net refers to a warm period about 1000 BC that brought agriculturalists to the Scandinavian coastline, but that was wrapped up about 500 BC and it was another half millenium before anybody else could bring agriculture (with improved methods and animals) back to that part of the world.
This is a case where ART HISTORY is lagging way behind DNA studies that clearly establish that the earlier populations of Sa'ami were NOT (closely) related (in time) to the far more recent populations of Norse from Europe.
Reporters are just hopeless when it comes to stuff like this.
Since the term “Nordic” doesn’t appear either in the excerpt or in the full article, what you’re engaged in there is a classic straw man argument.
