 IJ split in a typically disjunctive, almost mutually-exclusive geographical pattern, with J-M304 far more common in Arabia, and I-M170 far more common in Europe; the age of IJ and its subclades suggest that IJ probably entered Europe through the Balkans, some time before the last glacial maximum (about 26,500 years BP).The same geographic corridor (the Balkans) also supported later gene flows, including the Early Neolithic Farmers from Anatolia about 9,000 years BP.Found at low frequency in parts of Iran
