The first J1 men lived in late Upper Palaeolithic, shortly before the end of the last glacial period. The earliest J1 sample identified to date is from Satsurblia Cave (approximately 13200 BC) in Georgia (Jones et al (2015)), placing the origins of the J1 haplogroup around the Caucasus, Zagros and eastern Anatolia during the Upper Palaeolithic.
Like many other successful lineages in the Middle East, J1 is believed to have undergone a major expansion of its population 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 the heart of Kurdistan. Eastern Anatolia and the Zagros Mountains are the region where goats and sheep were domesticated for the first time 11,000 years ago. Chiaroni et al. Have estimated that J1-P58 began to spread from there to 10,000 to 9,000 years of here with the nomadic breeders of the Fertile Crescent. Although they did not analyze the other branches of J1, it is highly probable that all the lines of J1a1b (L136) that survived until today share the same origin, descending from the goat and sheep breeders From the Taurus and Zagros mountain ranges.
