Dr. King also notes an interesting correlation with a subclade of Haplogroup J2, M67, and place names in the Aegean, Balkans and Italy while citing a deeper origin for subclade M67 in Northern Syria or southern Anatolia. The age and spread of M67 seems associated with proto-greek substratum in the Aegean.
Some of the most interesting theories put forth in the chapter deal with linguistics. While noting that multiple haplogroups are likely involved in the spread of languages through the middle east, Dr. King noted a correlation between very old Middle Eastern languages of uncertain origin and Haplogroup J2 while at the same time theorizing that Haplogroup J1 may have been involved in spreading Semitic languages through the region. These old languages possibly linked to J2 are known to have existed in Mesopotamia and the Northern Levant and this substratum is sometimes referred to as "Banana" languages due to their syllabic duplication.
Underlying both these migrations, there may have been a population dating to the LGM characterized by J2 Y lineages whose set of languages is unknown but may have included syllabic reduplication in their morphology... Immediately after the LGM, southeast Anatolia, northern Syria and coastal Palestine may have provided refugia to populations marked by J2 lineages of uncertain linguistic character.
