J2:
J1 Origins & History
The first J1 men lived in the Late Upper Paleolithic, shortly before the end of the last Ice Age. The oldest identified J1 sample to date comes from Satsurblia cave (c. 13200 BCE) in Georgia (Jones et al. (2015)), placing the origins of haplogroup J1 in all likelihood in the region around the Caucasus, Zagros, Taurus and eastern Anatolia during the Upper Paleolithic.
Like many other successful lineages from the Middle East, J1 is thought to have undergone a major population expansion during the Neolithic period. Chiaroni et al. (2010) found that the greatest genetic diversity of J1 haplotypes was found in eastern Anatolia, near Lake Van in central Kurdistan. Eastern Anatolia and the Zagros mountains are the region where goats and sheep were first domesticated, some 11,000 years ago. Chiaroni et al. estimated that J1-P58 started expanding 9,000 to 10,000 years ago as pastoralists from the Fertile Crescent. Although they did not analyze the other branches, it is likely that all surviving J1a1b (L136) lineages share the same origin as goat and sheep herders from the Taurus and Zagros mountains.
The mountainous terrain of the Caucasus, Anatolia and modern Iran, which wasn't suitable for early cereal farming, was an ideal ground for goat and sheep herding and catalyzed the propagation of J1 pastoralists. Having colonised most of Anatolia, J1 herders would have settled the mountainous regions of Europe, including the southern Balkans, the Carpathians, central and southern Italy (Apennines, Sicily, Sardinia), southern France (especially Auvergne), and most of the Iberian peninsula. Hotspots of J1 in northern Spain (Cantabria, Asturias) appear to be essentially lineages descended from these Southwest Asian Neolithic herders.
J2 Origins
Haplogroup J2 is thought to have appeared somewhere in the Middle East towards the end of the last glaciation, between 15,000 and 22,000 years ago. The oldest known J2a samples at present were identified in remains from the Hotu Cave in northern Iran, dating from 9100-8600 BCE (Lazaridis et al. 2016), and from Kotias Klde in Georgia, dating from 7940-7600 BCE (Jones et al. (2015)). This confirms that haplogroup J2 was already found around the Caucasus and the southern Caspian region during the Mesolithic period. The first appearance of J2 during the Neolithic came in the form of a 10,000 year-old J2b sample from Tepe Abdul Hosein in north-western Iran in what was then the Pre-Pottery Neolithic (Broushaki et al. 2016).
It says Western Asia on your links. On my map (world map of Y-DNA) it shows Arabia.
If you use simple logic you will see that the region (Middle East/West Asia) was first inhabited by migrants from the Arabian Peninsula as that was the area of the world that was first inhabited after Africa.
Just google "human migration world map" and you will see all maps show Arabia as the stepping stone to the remaining world.
Western Asia also means Arabian Peninsula. In fact this is the largest part of Western Asia.
Haplogroup J-M304 is believed to have arisen roughly 48,000 years ago in Western Asia.[1] It is most closely related to the haplogroup I-M170, as both lineages are haplogroup IJ subclades. Haplogroup IJ and haplogroup K derive from haplogroup IJK, and only at this level of classification does haplogroup IJK join with Haplogroup G-M201 and Haplogroup H as immediate descendants of Haplogroup F-M89. J-M304 is defined by the M304 genetic marker, or the equivalent 12f2.1 marker. The main current subgroups J-M267 and J-M172, which now comprise between them almost all of the haplogroup's descendant lineages, are both believed to have arisen very early, at least 10,000 years ago. Nonetheless, Y-chromosomes F-M89* and IJ-M429* were reported to have been observed in the Iranian plateau (Grugni et al. 2012).
On the other hand, it would seem to be that different episodes of populace movement had impacted southeast Europe, as well as the role of the Balkans as a long-standing corridor to Europe from the Near East is shown by the phylogenetic unification of Hgs I and J by the basal M429 mutation. This proof of common ancestry suggests that ancestral Hgs IJ-M429* probably would have entered Europe through the Balkan track sometime before the LGM. They then subsequently split into Hg J and Hg I in Middle East and Europe in a typical disjunctive phylogeographic pattern. Such a geographic hall[clarification needed] is prone to have encountered extra consequent gene streams, including the horticultural settlers. Moreover, the unification of haplogroups IJK creates evolutionary distance from F–H delegates, as well as supporting the inference that both IJ-M429 and KT-M9 arose closer to the Middle East than central or eastern Asia.[citation needed]
Haplogroup J has also been found among two ancient Egyptian mummies excavated at the Abusir el-Meleq archaeological site in Middle Egypt, which date from a period between the late New Kingdom and the Roman era.[3]

The greatest concentration is also in Arabia. This points to its origin being there. Usually the greater diversity the more likely for an founder origin. That's how Darwin conclude that humans originated from Africa due to the diversity being greater there (animal and plant life) in the world. His theory turned out to be correct.
Haplogroup J-M304 is found in its greatest concentration in the Arabian peninsula. Outside of this region, haplogroup J-M304 has a significant presence in North Africa and the Horn of Africa. It also has a moderate occurrence in Southern Europe, especially in central and southern Italy, Malta, Greece and Albania. The J-M410 subclade is mostly distributed in Anatolia, Greece and southern Italy. Additionally, J-M304 is observed in Central Asia and South Asia, particularly in the form of its subclade J-M172. J-12f2 and J-P19 are also found among the Herero (8%).[4]
The basal haplogroup J*(xJ1, J2) is found at its highest frequencies among the Soqotri (71.4%).[5]
BTW do you know how long ago 48.000 years is? Everyone back then was as Black as this person below;
White skin originates in the Sham (Levant) where farming originated.
Pale skin probably arrived in Britain with a migration of people from the Middle East around 6,000 years ago. This population had pale skin and brown eyes and absorbed populations like the ones Cheddar Man belonged to.
No-one's entirely sure why pale skin evolved in these farmers, but their cereal-based diet was probably deficient in Vitamin D. This would have required agriculturalists to absorb this essential nutrient from sunlight through their skin.
"There may be other factors that are causing lower skin pigmentation over time in the last 10,000 years. But that's the big explanation that most scientists turn to," said Prof Thomas.
I have been saying this for years as it made the most sense. Glad that my "theory" has been proven correct.
There were no "Arabs", "Iranians", "Turks" 48.000 years ago FFS.
The oldest linguistic family group (Afro-Asiatic) is not even 25.000 years old. We don't know anything about which languages people spoke 30.000 years ago. Zero information.
Somehow the BBC links is not showing.
Just google
