Excellent info, though I'm puzzled by this statement:

A particularly intriguing case illustrating this is that of the Kurdish Jews, said to be the descendants of the Ten Tribes of Israel who were exiled in 723 BCE.

They were either descendents of the northern Ten Tribes (Israel) or the southern kingdom (Judea) by Judah or Benjamin, and hence, Jews.

The study seems to go back to before the separation to a "common ancient Israelite father".
