I was recently wondering why the agricultural revolution that took place in the Middle East during the Neolithic period propelled certain "middle eastern" markers further to success into Europe than it did others. We all know that E3b arrived from North Africa to the Balkans (southeastern Europe) and at lower % in Iberia and Sicily/Sardinia/Italy. Some E3b also migrated to the Levantine region of the Middle East. E3b along with J2, where the most successfull Neolithic markers in terms of colonizing Mediterranean Europe. J2 had much distance to travel, from the fringes of the mesopotamian world (its homeland, and where it still dominates today) all the way to parts of southeastern Europe and as far as Iberia at lower % than Italy/Greece and their respective islands, of course (excluding Sardinia.) J2-M172 seems to have had very little genetic impact in North Africa; it is hardly present there. J1-M267, the more "Semitic", "southern middle eastern" subclade of J that dominates Arabia proper, seems to have left very scarce genetic trails/impact on Europe, insignificant impact in fact. But during the Middle Ages, J1 men, and the Islam they brought with them, crossed all of North Africa with their camels, affecting North Africa at about the same frequencies that J2 earlier ended up affecting Europe. J1 affects some 25% of Algerians, 10-20% Moroccans, 20-30% Tunisians, 15-20% Egyptians etc. blood from the Arabian peninsula. As for hg G, it seems to have originated farther out, more towards Central Asia, on the fringes of central Iran, from where it would later migrate to the Caucasus from where the P15 lineage would shoot through turkey, Greece, Italy, and to northern Sardinia where it would father Nuraghic culture. G, G2 in particular, affects Europeans at very low frequencies, with a high of 15-20% in Sardinia , 15% in southern Italy (9% on a national level) and some 8% of Greeks. This may be because G originated much farther out in the first place, and even then was overwhelmed by agriculturalists in the Middle East, that out competed hg G2 and T hunter-gatherers. Same for the M70 lineage, it probably originated somewhere near Afghanistan, Tajikistan and extreme eastern Iran, not directly in Mesopotamia, but farther out near Central Asia and the Pamir knot region; from there it infiltrated the Middle East/north Africa ( Egypt and Horn of Africa in particular). From the Middle East, it infiltrated Europe at very low percentages, probably due to its "origin point" distance to Europe.
