Haplogrup F of "Oase 1" (from "Peștera cu oase", Romania), a clue to the European origin of haplogroups G, H, I, J, K ?
Oase 1 lived ~ 37,000 - 42,000 years ago. Other 29,000-year-old remains have been found in the Czech Republic and belong to the Y-haplogroup IJK. I think it can be an indication that the European population could be dominated about 40,000 years ago and more, by the haplogroup F.

Considering the time of the formation of daughter haplogroups, and the time required for their expansion, I think it is possible that G, H, I, J, K formed in Europe more than 40,000 years ago, being contemporary with "Oase 1".

F - TMRCA 48800 ybp -> GHIJK - formed 48800 ybp -> HIJK formed 48500 ybp -> IJK formed 48500 ybp

G - formed 48500 ybp

H - formed 48500 ybp

K- formed 47200 ybp

I - formed 42900 ybp

J - formed 42900 ybp

What do you think?

p.s.
Possibly during the last maximum glaciation that started ~ 33,000 years ago. These haplogroups retreated to southern Europe and Anatolia/Middle East, from where, in particular I, then great part of G and part of J returned to the end of the glaciation, with H and K spreading mainly to southern Asia.
