Haplogroup J (Y-DNA)
J is Originally from Eastern Anatolia, divided into the northern J2 and the southern J1. J2 is by far the most common variety in Europe.
J1 is a typically Taurid Zarzian capsian haplogroup, most common of the population of the Arabian peninsula. and among some Kushitic / Nubian Tribes and hamitic groups of sudan and ethiopia . Its highest density is observed in Khartoum Sudan (74%), its also Present in Europe, Middle East, North Africa,
he "J1* with DYS388 = 13 or 14, L136-, P58- sub-clade" is considered by Dr. Roy King of Stanford University to be one of the markers of the Caucasian-speaking Hurrians and Urartians in historic times.
While J1e (now called J1c3d) is predominantly Arab & African this branch of haplogroup J1 is more ancient than these two groups. It also contains other Near Eastern, Anatolian and Caucasus Mountain ethnic groups. Quoting Jacques Chiaroni, Roy King et al.: "The highest YSTR variance of J1e lineages is in eastern Anatolia, northern Iraq and northwest Iran... The somewhat rare J1e1-M368 provides an insight into the geographical origin of J1e. It has been reported both in the Black Sea region of Turkey and Dagestan in the northeast Caucasus. Furthermore, J1e1-M368 displays the YCAII 19-22 pattern. Although the haplogroup relationships of YCAII alleles are unstable, nevertheless in the context of haplogroup J1, they are suggestive that the prevalent YCAII 22-22 variety may have evolved from a YCAII 19-22 ancestor. The current data suggest an origin of J1e in the general area of eastern Turkey/northern Iraq associated with the Zarzian horizon, as they have similar early pre-agricultural expansions [16,000 years ago]... The timing and geographical distribution of J1e is representative of a demic expansion of agriculturalists and herder--hunters from the Pre-Pottery Neolithic B to the late Neolithic era...
J2 originated in Eastern Anatolia, and spread westward to western Anatolia and southern Europe, and eastward to Persia and India. J2 is related to the Ancient Etruscans, (Minoan) Greeks, southern Anatolians, Assyrians and Babylonians.
In Europe, J2 reaches its highest frequency in Greece (especially in Crete, Peloponese and Thrace), southern and central Italy, southern France, and southern Spain. The ancient Greeks and indu-europeans were the main driving forces behind the spread J2 around the western and southern Mediterranean.
J2 is thought to have arrived in Greece from Anatolia somtime between the (late) Neolithic and the Bronze Age.
