Prevailing archeological and genetic evidence suggests that the traditional paradigm of a massive bidirectional deportation between Samaria and Mesopotamia is apocryphal and that today's Jews and Samaritans are closely related relative to neighboring groups, having a shared descent from a Y-chromosomal Aaron dating back to the Assyrian conquest of the northern Israelites. The age of the Samaritan Pentateuch relative to the Masoretic Text and the Septuagint appears to be a subject of wide academic controversy, but its antiquity based on its deviations from each of those texts is reportedly corroborated by other manuscripts such as those of the Vitus Latina and Dead Sea Scrolls. Intermarriage with or without proselytism would have resulted in centuries of admixture between ethnic Jews from the Kingdoms of Judea and Israel and the non-Jewish denizens of surrounding kingdoms. What leads you to claim that most of their descendants renounced Judaism by the time of Jesus' birth? As far as I've found, the proportional demographic breakdown of Roman Palestine is unknown. Thank you for your enlightening analysis of the philosophies and practices of Jesus. While this evidence doesn't say anything definitive of his ancestry or racial origins, it may make it highly probable that at least some of his immediate family members were ethnically Judean. Because the scholarship knows so little about his origins however, the possibility that he or any of his ancestors were taken up and reared by another family cannot be discounted. And yes, Canaanite is an umbrella term for all indigenous inhabitants of the biblically demarcated land of Canaan, which would encompass a number of ethnic groups including nomadic peoples such as the Shasu and Habiru and possibly some assimilated Egyptians. These groups seem to have been united under a uniquely Canaanite culture in that region, which included the Canaanite religion, itself a syncretization of Akkadian and Sumerian beliefs. By the time the Yahwistic monoltry emerged, a distinct Canaanite culture had developed from the convergence of all preceding ethnic influences, a culture which wholly and directly gave rise to the first Israelite settlements.
