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.[3] Later study in 2023 with high quality sequencing of Magdalenian, GoyetQ-2, Gravettian, Vestonice16 were assigned with Haplogroup I.[4]
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:
K2* – the basal subclade is found at significant levels among indigenous Australians. Also found at Mandar and Toba Batak one of the Indigenous Tribe in Sundaland.[5]
NO* † (found only in the remains of Ust'-Ishim man,<br /> dating from 45,000 BP [7]) → NO1 (K2a)

^K-M2313*, which as yet has no phylogenetic name, has been documented in two living individuals, who have ethnic ties to India and South East Asia. In addition, K-Y28299, which appears to be a primary branch of K-M2313, has been found in three living individuals from India.
