Jewish people have a greater diversity of top-level haplogroups than almost any other ethnic/national group in Europe and the Middle East. However this diversity is illusive as for each haplogroup only some deep and very specific subclades are present among paternal Jewish lineages. The European Jewish population (Ashkenazi and Sephardi) underwent a major bottleneck during the Early Middle Ages. The purpose of this thread is to estimate when this bottleneck occurred based on the age estimates and time to most recent common ancestor (TMRCA) for each specifically Jewish deep clade.
E-Y14891 : formed 7200 ybp, TMRCA 1200 ybp
E-Y6923 : formed 5400 ybp, TMRCA 1150 ybp
G2b1b-Y12975 (aka FGC32402) : formed 5500 ybp, TMRCA 1200 ybp
J1-ZS227 (aka Y3081) : formed 5600 ybp, TMRCA 3300 ybp (Yfull) / 2270-3540 ybp (Marko T. Heinilä & Iain McDonald)
- J1-Z18271 (Y-chromosomal Aron) : formed 2750 ybp / 2625 ybp (Iain McDonald)
J1-L816 : formed 4000 ybp, TMRCA 1150 ybp (Yfull) / 1000-1520 ybp (Iain McDonald & Marko T. Heinilä)
J1-L823 : formed 1430-1570 ybp (Marko T. Heinilä & Iain McDonald)
J2-Y15223 : formed 2500 ybp, TMRCA 1200 ybp (Yfull)
J2-L254 : ?
J2-L556 : formed 6000 ybp, TMRCA 1150 ybp (Yfull)
J2-L590 : ?
Q1b-Y2200 : formed 2600 ybp, TMRCA 1550 ybp (Yfull)
R1a-Y2619 (aka Y2630) : formed 2800 ybp, TMRCA 1400 ybp (Yfull)
R1b-FGC20980 (under V88) : formed 3600 ybp, TMRCA 1050 ybp
R1b-L4 (under U152>Z56) : ?
Based on these estimates, it appears that the bottleneck took place between 1100 and 1500 years ago (i.e. between 500 and 900 CE). The only lineage that did not experience this bottleneck, perhaps because it is the only lineage in common with non-European Jews, is the Cohanim J1-ZS227.
Based on the age of those haplogroups, it looks like the original Jewish/Semitic lineages were E-M34, G2b1b, J1-P58, J2a1-M67 and J2a1-PF4888. There might have been some T1a, but I couldn't find what lineage was specifically Jewish. R1a-Z93, R1b-V88 and Q1b would have integrated Jewish/Israelite society during the Bronze Age. It is completely expected of R1a-Z93 and Q1b, which came with the Indo-Iranian invasions, but R1b-V88 has been in the Levant since the Early Neolithic. I don't understand why the Jewish clade shouldn't have an older age of formation than 3600 ybp.
