Possible time of origin	47,000-60,000
Possible place of origin	Southwest Asia
Ancestor	Haplogroup HIJK

Defining mutations	L15/S137, L16/S138, L69.1(=G)/S163.1

Haplogroup IJK is a human Y-chromosome DNA haplogroup. IJK is a primary branch of the macrohaplogroup HIJK. Its direct descendants are Haplogroup IJ and Haplogroup K.

The basal paragroup HIJK* has not been identified in living males or ancient remains.

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:

I1 found mainly in Northern Europe.

I2found mainly in Southern Europe

J1 found mainly in the Middle East.

J2 found mainly in the Middle East, Caucasus, Central Asia, South Asia and Southeast Europe.

L found mainly in Central Asia, South Asia and Western Asia.

T now concentrated in the Horn of Africa, the Arabian subcontinent, India and Eurasia.
