IJK has not been reported in modern populations or in ancient human remains. Previously, basal paragroup HIJK* was reported in a
Mesolithic European (
Magdalenian), GoyetQ-2, and
Upper Paleolithic European (
Gravettian), Vestonice16. However, in a later study in 2023 with high quality sequencing of
Magdalenian, GoyetQ-2,
Gravettian, Vestonice16, the ancient human remains were assigned with
Haplogroup I. Populations with high proportions of males who belong to descendant major haplogroups of Haplogroup HIJK live across widely dispersed areas and populations. Subclades of IJK are now concentrated in males native to: •
Europe (e. g. haplogroups I, J, R and N); • the
Caucasus,
Near East and
North East Africa (e.g. haplogroups J and T); •
South Asia (e.g. haplogroups J, L and R); •
East Asia，
Southeast Asia,
Oceania, and the
Pacific (e. g. haplogroups K, M, O, P, S) •
Northern Eurasia, (e.g. haplogroups N and Q) and; •
Native American peoples (e. g. haplogroup Q and R).
