J1 is a cool lineage associated with the spread of Semitic languages and peoples, at least its P58 subclade.
The second major subclade is Z1842, in Caucasus and Anatolia, found recently in Bronze Age Anatolia in a city that theoretically by that time should have had Anatolian IE speakers, I wonder if the subclade is ultimately Indo-European.
Most cases of J1 in non-Mediterranean Europe is a consequence of the Roman Empire's settling its veterans in its provinces, many came from the Balkans, but also Syria, Anatolia, North Africa etc..
I think J1 predates the spread of Semitic languages and peoples. P58's TMRCA is 9,000 years old, the clade itself is 14,300 years old.
