Not really. Apparently there are very few ‘Egyptians’ left in Egypt. They have been replaced by Arabs.............What this article means is that the true Egyptians migrated into Europe millenia ago and became the ‘natives’...................
That’s another possibility.
It’s possible, but unlikely that the Ancient Egyptians originally came from Europe. More likely, that they came from the black sea region at the beginning of the holocene, and eventually migrated down there.
So the only contact between Europeans and Egyptians would have been a very long time ago. It all depends on which half of the British people turn out to have the Tut connection. If it’s the half that were there prior to the Romans (ie, Celtiberians, etc, then yes, it would go back to there.
If it turns up in the Roman era Britons, then that would be very cool, and would likely imply that the connection runs from Egypt to Europe. Which would be really cool.
It can mean a lot of things, but that seems like one of the less likely explanations.
It could just mean that the Egyptian royal family had a strong European strain at the time, from even a rather distant ancestor.
Cavalli-Sforza has shown that for the most part genetic variation among human populations is gradual by distance, barring isolation, except where a small pre-agricultural population was replaced by a much more numerous agricultural one - because agriculture supports orders of magnitudes more people.
Once there are millions of peasants living on the land it is quite difficult to get rid of them.
