There are some here who claim I is indigenous to Europe, non neolithic, while claiming that J is neolithic.
According to what I found. Haplogroup I and J were one haplogroup, haplogroup IJ. They split from eachother.. Either in the Caucasus or western Asia. Or they migrated together into Europe carried by cro magnons
European point of origin for I-M170 is generally proposed. However, the concentration of its sibling Haplogroup J (M304) in South West Asia, and the discovery in 2012 of living examples of Haplogroup IJ* in Iran, may imply that all three haplogroups originated closer to Anatolia and/or the Caucasus.[2]
"While old estimates suggested that the most recent common ancestor of haplogroup IJ could have lived 30,500 years ago, the latest estimates suggest that he lived 42,400–46,400 years before present.[1][3]
Both of the primary branches of haplogroup IJ – I-M170 and J-M304 – are found among modern populations of the Caucasus, Anatolia, and Southwest Asia. This tends to suggest that Haplogroup IJ branched from IJK in West Asia and/or the Middle East."
If haplogroup I is indigenous to Europe or if it's rather neolithic then surely so is J.
"IJ split in a typical, disjunctive, almost mutually-exclusive geographical pattern, with J-M304 far more common in the Middle East 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) is likely to have supported subsequent gene flows, including some identified with early European farmers (from about 9,000 years BP)."
Basically J is more common in the south while I is more north. But what makes J neolithic any more then I?
