I don't think this says a lot.
Of course you don't. Why let pesky reality intrude into your apocalyptic fantasy world?
We have no samples of Edomite genes, to my knowledge, to perform a similar study.
That isn't the point. What I am trying to tell you is that if modern Palestinians are descended from the Edomites,
then so are the Israelis. The genetic evidence is that they are essentially the same people. Your silly argument that Palestinians are Edomites could just as easily (and just as wrongly) be applied to the Israelis, which kind of screws up the picture you are trying to paint.
Your scenario simply makes no sense if both the Palestinians and Israelis are Edomites.
