Haplogroup J-M304, also known as J, is a human Y-chromosome DNA haplogroup. It is believed to have evolved in the Caucasus or Iran.' The clade spread from there during the Neolithic, primarily into North Africa, the Horn of Africa, the Socotra Archipelago, Europe, Anatolia, Central Asia, South Asia, and Southeast Asia.
Haplogroup J-M304 is divided into two main subclades (branches), J-M267 and J-M172.
