Hmmm....how come the different haplogroups then?
You're missing the point BB. What's with your fixation with haplogroups? The source I provided is from the article published by Uppsala University. The only reason why the DNA analysis was performed on the hair found in the book owned by Copernicus and kept at the Museum of that University, was to strengthen the case that the remains found are indeed those of Copernicus. As for proving his nationality, it's just wishful thinking on your part. I guess your selective reading will not let you understand the problem at hand.
In any case, the analysis of the hair resulted in interpretable profiles for four of the strains of hair. Of these, two of the strains have the same profile as the remains suspected to be those of Copernicus himself, as compared to the sample of hair found in the book which was owned by Copernicus. This would indicate that they are indeed those of Copernicus, but only as circumstantial evidence - not as proof positive.
The two matching samples of the hair might have as well belong to one of his relatives on his mothers side of the family, as well as the corps suspected to be those of Copernicus, this would explain the match and the two remaining samples that are not a match, could be his. This test can't prove or disprove this scenario and there's also a possibility of a random match. However this test dose prove that in all probability it's the same individual.
The point is they don't know for sure. The debate itself, still is whether or not those are the remains of Copernicus and you're jumping the gun by analysing haplogroups, stating that these are the remains of a German. They very well may be, after all we do know he comes from a mixed family, besides there are plenty of Germans buried in Poland and vice versa.
PS. The source that you provided, proves to me how desperate the Germans are to prove he's German. Without having concluded one debate, you start another. Like it's a done deal. LOL For goodness sake, let's come to an agreement whether or not those are the remains of the man in question in a first place, before opening Pandoras' box with your bombshell.
