King Tut appears to be Celtic. This does not mean that his ancestors lived in Ireland. It means that the same people that Tut was descended from ultimately migrated there.
Regarding the argument that "Egyptians were Africans", agriculture was first developed somewhere around Iraq. I could see people spreading out from there in search of fertile farming land, finding the Nile valley, and displacing/killing any black Africans they found. Thus, while living in Africa, they would be no more "African" than the whites of South Africa.
This does not mean that his ancestors lived in Ireland.
That was the primary conclusion but with more data they then said he was related to half of European males. I keep hoping for more European DNA studies.
Think about this-
Celts and ..... Teutons.
King Tut. King Teuton. King Teutoncommon. King Tutankhamun.
