Yep, evidence keeps getting uncovered to make that appear true.
I read an interesting (for it's photos) but otherwise dreadful article on the Scythians today in a 6 year old National Geographic. The editor got most everything wrong and just couldn't bring himself to admit these Scythians were CELTS, in the exact place (north of the Black Sea), and the exact time (7th Century BC) where 5 MILLION CELTS suddenly appear in history. He even had them going in the wrong direction.
It was right there hitting him in the head and he couldn't see it. (Probably too busy thinking about another upcoming article on bugs or "global warming"...)
