Yes, there ARE "dark" Hungarians, but that describes hair color!
And since they have discovered human bones, in China, that are far older than the most ancient human bones found in Africa, this whole "story", as far as I'm concerned, is suspect!
And though not names, this report claimed that "MIDDLE EUROPEAN" nations (Austria, Poland,The Czech Republic, Slovakia, and Germany all fall into this category, if Hungary does! ) are peopled by a whole lot of pale, blonde blue eyed human beings and have been for thousands of years!
Also in this report, they claim that only the ancient people of the Scandinavian nations had pale skin and hair...perhaps brought to them by INDIANS/people from the Steps of Russia? THIS JUST MAKES NO SENSE AT ALL!
There is also the process of environmental mutation where changes in the DNA can occur within a relatively short amount of time passes down directly from within ones own family.
I have to ask myself, how much of what one does personally and comes into contact within ones personal environment shapes the genes of your decendants for generations?
