In Genetic genealogy and human genetics, Y DNA haplogroup J-M267, also commonly known as Haplogroup J1 is a subclade (branch) of Y-DNA haplogroup J-P209, (commonly known as Haplogroup J) along with its sibling clade Y DNA haplogroup J-M172 (commonly known as Haplogroup J2). (All these haplogroups have had other historical names listed below.)
Men from this lineage share a common paternal ancestor, which is demonstrated and defined by the presence of the SNP mutation referred to as M267, which was announced in (Cinnioğlu 2004). This haplogroup is found today in significant frequencies in many areas in or near the Middle East, and parts of the Caucasus, Sudan and Ethiopia. It is also found in high frequencies in parts of North Africa, Southern Europe, and amongst Jewish groups, especially those with Cohen surnames. It can also be found much less commonly, but still occasionally in significant amounts, throughout Europe and as far east as Central Asia and the Indian Subcontinent.
Since the discovery of haplogroup J-P209 it has generally been recognized that it shows signs of having originated in or near West Asia. The frequency and diversity of both its major branches, J-M267 and J-M172, in that region makes them candidates as genetic markers of the spread of farming technology during the Neolithic, which is proposed to have had a major impact upon human populations.
