The only study similar to this I can currently think of is the Kushite (no, not the Kerman sample) study.
They sampled
royals from king Nastasen’s tomb.

Now that I think about it since they’ve mentioned el-Kurru, it’s reasonable to say we’re talking about the same thing. You know, Nastasen being the last of Napatan Period kings and such.
I believe this is the Kushite study I mentioned in another thread. I am pretty sure Apollo had brought this up a few years ago.
We might have to wait for 2-3 years though.
But eventually the literal kangz will reveal their secrets to us.
