The haplogroup J1, the ancestor of subclade M267, originates south of the Levant and was first disseminated from there into Ethiopia and Europe in Neolithic times. In Jewish populations, J1 has a rate of around 15%, with haplogroup J2 (M172) (of eight sub-Haplogroups) being almost twice as common as J1 among Jews (<29%). J1 is most common in Palestine, as well as Syria, Iraq, Algeria, and Arabia, and drops sharply at the border of non-semitic areas like Turkey and Iran. A second diffusion of the J1 marker took place in the 7th century CE when Arabians brought it from Arabia to North Africa.
