Palestinians are very similar to Jews genetically, according to Haaretz, as are Druze and Bedouins.@IshChayil indeed, somevery interesting finds in Afghanistan and Pakistan recently w Muslim tribes that trace lineage and custom directly into Biblical or Judaic practice.

Which makes sense. Palestine was populated with many Jews and Jewish converts to Christianity, until the Muslims took over. For obvious reasons, large portions of the Jewish and Christian population converted to Islam, while some did not - making many of the Muslims in Palestine ethnically Jewish. Roll forward to today, and their descendants are the Palestinians. Obviously, lots of genetic mixing and migrations have occurred both in the population that stayed in Palestine and converted to Islam or Christianity, and in the population that was dispersed and retained the Jewish religion. So I'm not at all saying that every Palestinian is ethnically Jewish. But, based purely on history, supported by modern genetics, it is most reasonable to assume that a fair portion of the Palestinian population (both Muslim and Christian) is ethnically Jewish.The closest genetic neighbors to most Jewish groups were the Palestinians, Israeli Bedouins, and Druze in addition to the Southern Europeans, including Cypriots
No doubt there are people groups with Jewish ancestry in many other places all over the world. But I would expect the largest undiscovered (or rather unrecognised) population to be closer to Israel for purely historical reasons, and genetics supports that strongly.
This is a fascinating chart from a research summary. Have a look at it and see what you notice before reading my next comment:
What jumps out to me is that the Palestinians and Druze are smack between the European, North African and Yemeni Jews, and the Bedouin are right beside them. Genetically, these groups are indistinguishable from Jews if you take the Yemeni + European + N.African populations as collectively representing Jews. If you include the Ethiopian Jews, then it gets even more complex. Clearly there is an enormous amount of Jewish blood in the Palestinians.
The political ramifications of this are obviously rather enormous, but I'm just talking about the science. Ponder the politics yourself...
