- 2026-06-21-note-07 — J-Z640, a Bronze-Age Levantine subclade of J1-P58 — Canaanite founder population, rapid Bronze-Age expansion, then post-collapse “differentiation by culture” partitioning one paternal lineage across Near Eastern ethno-religious communities (Waas et al. 2019) (2026-06-21)
- 2026-06-21-note-09 — Why J-Z640 is placed in the Levant and not Arabia — the GIS origin argument and the ruling-out of an Arabian origin (interior Arabia uninhabitable / no long-distance trade until camel domestication ~1000 BCE), plus Mesopotamia and Iberia discounted (Waas et al. 2019) (2026-06-21)
- 2026-06-21-note-10 — The Late Bronze Age world-system as the engine of J-Z640’s expansion (globalism, territorial states, trade + low-level warfare + rural displacement → population boom recorded by the cluster of ancient branches) and why the founder population best fits the Canaanites rather than Egyptians/Hittites/Mitanni/Aegeans (Waas et al. 2019) (2026-06-21)
- 2026-06-21-note-11 — The Arab branches of J-Z640 and the al-Azd tribes — ancient basal Bronze-Age lineages (oldest = J-BY74) whose carriers self-report al-Azd descent; Ulrich’s 3rd–4th c. CE Azd tribal “kingdoms”; genetics cannot confirm/disprove the link but the branch ages, STR data and number of self-identified Azd carriers indicate a long-standing tribal association (Waas et al. 2019) (2026-06-21)
- 2026-06-21-note-12 — The history of the term “Arab” and Arab ethnogenesis — Ephʿal (an external northern label for Fertile-Crescent nomads; Shalmaneser III’s 853 BCE inscription on Gindibu’s camels) and Webb (an externally imposed label that faded after the 3rd c. CE and was reimagined as an ethnoreligious identity with the rise of Islam), tied to camel-nomadism and al-Azd prominence (Waas et al. 2019) (2026-06-21)
- 2026-06-21-note-13 — J-Z640’s European reach and the single Sardinian sample from Cagliari (subclade J-Z642) as a possible genetic remnant of the Phoenician colonies (750–650 BCE) — set against the deeper Eastern-Mediterranean expansions (Zalloua) and the ~1200 BCE threshold for crossing the whole Mediterranean; rarity leaves a later arrival open (Waas et al. 2019) (2026-06-21)
- 2026-06-21-note-14 — The Sephardic/Iberian branches of J-Z640 as a genetic echo of the Golden Age of al-Andalus — exclusively Sephardic lineages (some Portuguese New Christians); the three branches of J-FGC5206 most probably emerged during the documented Jewish population boom in Iberia (25,000 c.800–900 CE → more than doubled by the 11th c → southern-Spain Jews surpassing all of Europe by the 12th) (Waas et al. 2019) (2026-06-21)
