Haplogroup HIJK

HIJK branches subsequently into two direct descendants: IJK (L15/M523/PF3492/S137) and H (L901/M2939). IJK in turn splits into IJ (F-L15) and K (M9). The descendants of Haplogroup IJ are haplogroups I and J, while Haplogroup K is, ultimately, the ancestor of major haplogroups M, N, O, P, Q, R, S, L, and T.

Distribution

HIJK 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. Later study in 2023 with high quality sequencing of Magdalenian, GoyetQ-2, Gravettian, Vestonice16 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.

Males belonging to other subclades of IJK are concentrated in, for example:

• Europe and Central Asia (e. g. haplogroups I, J, N, Q and R);
• the Middle East and North East Africa (e. g. haplogroups J and T);
• South Asia (e.g. haplogroups H, J, L and R);
• Southeast Asia and East Asia (e.g. haplogroup N, O, P)
• Oceania (e. g. haplogroups P, K, M, O and S) and;
• many Native American peoples (e. g. haplogroup Q).
