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. [2]
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:

The defining SNP L15 is located at Y chromosomal location rs9786139 with the ancestral value being A and the derived value being G .
The defining SNP L16 is at location rs9786714 with the ancestral value being G and the derived value being A.
The Aurignacian is an archaeological industry of the Upper Paleolithic associated with Early European modern humans (EEMH) lasting from 43,000 to 26,000 years ago. The Upper Paleolithic developed in Europe some time after the Levant, where the Emiran period and the Ahmarian period form the first periods of the Upper Paleolithic, corresponding to the first stages of the expansion of Homo sapiens out of Africa. They then migrated to Europe and created the first European culture of modern humans, the Aurignacian.
A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplogroup is a combination of alleles at different chromosomal regions that are closely linked and that tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes. Haplogroups pertain to a single line of descent. As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual.
Haplogroup I (M170) is a Y-chromosome DNA haplogroup. It is a subgroup of haplogroup IJ, which itself is a derivative of the haplogroup IJK. Subclades I1 and I2 can be found in most present-day European populations, with peaks in some Northern European and Southeastern European countries.
Haplogroup J-M304, also known as J, is a human Y-chromosome DNA haplogroup. It is believed to have evolved in Western Asia. The clade spread from there during the Neolithic, primarily into North Africa, the Horn of Africa, the Socotra Archipelago, the Caucasus, Europe, Western Asia, Central Asia, South Asia, and Southeast Asia.
Haplogroup C is a major Y-chromosome haplogroup, defined by UEPs M130/RPS4Y711, P184, P255, and P260, which are all SNP mutations. It is one of two primary branches of Haplogroup CF alongside Haplogroup F. Haplogroup C is found in ancient populations on every continent except Africa and is the predominant Y-DNA haplogroup among males belonging to many peoples indigenous to East Asia, Central Asia, Siberia, North America and Australia as well as a some populations in Europe, the Levant, and later Japan. The haplogroup is also found with moderate to low frequency among many present-day populations of Southeast Asia, South Asia, and Southwest Asia.
Haplogroup F, also known as F-M89 and previously as Haplogroup FT is a very common Y-chromosome haplogroup. The clade and its subclades constitute over 90% of paternal lineages outside of Africa.
Haplogroup K or K-M9 is a human Y-chromosome DNA haplogroup. A sublineage of haplogroup IJK, K-M9, and its descendant clades represent a geographically widespread and diverse haplogroup. The lineages have long been found among males on every continent except Antarctica.
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by mutations in the non-recombining portions of DNA from the male-specific Y chromosome. Many people within a haplogroup share similar numbers of short tandem repeats (STRs) and types of mutations called single-nucleotide polymorphisms (SNPs).
Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread amongst modern populations.
The genetic history of Europe deals with the formation, ethnogenesis, and other DNA-specific information about populations indigenous, or living in Europe.
Haplogroup IJ (M429/P125) is a human Y-chromosome DNA haplogroup, an immediate descendant of Haplogroup IJK. IJK is a branch of Haplogroup HIJK.
Haplogroup CT is a human Y chromosome haplogroup, defining one of the major paternal lineages of humanity.
Haplogroup R1b (R-M343), previously known as Hg1 and Eu18, is a human Y-chromosome haplogroup.
In human population genetics, Y-Chromosome haplogroups define the major lineages of direct paternal (male) lines back to a shared common ancestor in Africa. Men in the same haplogroup share a set of differences, or markers, on their Y-Chromosome, which distinguish them from men in other haplogroups. These UEPs, or markers used to define haplogroups, are SNP mutations. Y-Chromosome Haplogroups all form "family trees" or "phylogenies", with both branches or sub-clades diverging from a common haplogroup ancestor, and also with all haplogroups themselves linked into one family tree which traces back ultimately to the most recent shared male line ancestor of all men alive today, called in popular science Y Chromosome Adam.
Haplogroup Q-P89.1 is a subclade of Y-DNA Haplogroup Q-MEH2. Haplogroup Q-P89.1 is defined by the presence of the P89.1 Single Nucleotide Polymorphism (SNP). In 2010, Q-P89.1 was reclassified as "private" and removed from the haplotree.
HaplogroupGHIJK, defined by the SNPs M3658, F1329, PF2622, and YSC0001299, is a common Y-chromosome haplogroup. This macrohaplogroup and its subclades contain the vast majority of the world's existing male population.
Haplogroup HIJK, defined by the SNPs F929, M578, PF3494 and S6397, is a common Y-chromosome haplogroup. Like its parent macrohaplogroup GHIJK, Haplogroup HIJK and its subclades comprise the vast majority of the world's male population.
Haplogroup C1 also known as C-F3393, is a major Y-chromosome haplogroup. It is one of two primary branches of the broader Haplogroup C, the other being C2.
The Goyet Caves are a series of connected caves located in Wallonia in a limestone cliff about 15 m (50 ft) above the river Samson near the village of Mozet in the Gesves municipality of the Namur province, Belgium. The site is a significant locality of regional Neanderthal and European early modern human occupation, as thousands of fossils and artifacts were discovered that are all attributed to a long and contiguous stratigraphic sequence from 120,000 years ago, the Middle Palaeolithic to less than 5.000 years ago, the late Neolithic. A robust sequence of sediments was identified during extensive excavations by geologist Edouard Dupont, who undertook the first probings as early as 1867. The site was added to the Belgian National Heritage register in 1976.
In archaeogenetics, the term Western Hunter-Gatherer (WHG), West European Hunter-Gatherer, Western European Hunter-Gatherer, Villabruna cluster, or Oberkassel cluster names a distinct ancestral component of modern Europeans, representing descent from a population of Mesolithic hunter-gatherers who scattered over Western, Southern and Central Europe, from the British Isles in the west to the Carpathians in the east, following the retreat of the ice sheet of the Last Glacial Maximum.
