"King Tut Related to Half of European Men? Maybe Not
But Carsten Pusch, a geneticist at Germany's University of Tubingen who was part of the team that unraveled Tut's DNA from samples taken from his mummy and mummies of his family members, said that iGENEA's claims are "simply impossible."
But that doesn't mean some Europeans aren't related. I think the money quote is here.
"The haplogroup R1b1a2, which iGENEA claims includes King Tut, arose 9,500 years ago in the Black Sea region."
If King Tut is of that haplotype (not established) he may have been related to the Minoans who are also thought to descend from the same Black Sea pliestocene population. This mass migration has been speculated to be the result of a great flood.
As was said in the thread about the Minoans, some Europeans are decended from the same population. When it comes right down to it, none of this is earth shaking but it is interesting.
From what I remember the Egyptians considered the Minoans the other civilized people with the rest of humanity being barbarians. So it is not a stretch to think that Minoan and Egyptian royals would have intermarried.
