"Not sure you are disputing what I said. The critical genetic markers at issue show that both the Jews (in general, but not in every case of every individual) and today's modern Palestinian populations are very closely related to the Kurds (the ancient Medes), and not closely related to the Arabs."

No... Read the links I cited. The Palestinian Arabs are indistinguishable from other Arabs. Arabs have a very high genetic incidence of EU Haplotype 10, which is different from other Middle Eastern populations (Jewish, Aramaic, Kurdish, Turkish, Persian, etc.):

"In comparison with data available from other relevant populations in the region, Jews were found to be more closely related to groups in the north of the Fertile Crescent (Kurds, Turks, and Armenians) than to their Arab neighbors. The two haplogroups Eu 9 and Eu 10 constitute a major part of the Y chromosome pool in the analyzed sample. Our data suggest that Eu 9 originated in the northern part, and Eu 10 in the southern part of the Fertile Crescent. Genetic dating yielded estimates of the expansion of both haplogroups that cover the Neolithic period in the region. Palestinian Arabs and Bedouin differed from the other Middle Eastern populations studied here, mainly in specific high-frequency Eu 10 haplotypes not found in the non-Arab groups. These chromosomes might have been introduced through migrations from the Arabian Peninsula during the last two millennia."

Contrary to propaganda, Arabs are not descendents of Canaanites.

Arabs invaded and conquered other countries in a series of genocidal jihads originating from Arabia in the 7th Century C.E. See the historical timeline of Arab expansion through the Middle East:
