Ken Nordtvedt says
"I2* has three main clades whose ancestral lines separated 8,000 years ago or so. One of them has a strong contribution from Armenia/Anatolia and elsewhere in SW Asia. And the Greek members of this clade add to its geographical uniqueness. It also has a very young Jewish sub-clade.
But two of the clades of I2* are purely European --- and northwest and central Europe to boot, although a few Italian haplotypes are included
These latter two clades of I2* have an interclade node age estimate of 7500 years."
"The more I look at the overall clade which includes the Armenian/Turkish cluster, the more I see a clade spread by a trading family or clan across the breadth from Iberia to the Caucasus and across the Mediterranean. Where it originates is hard to determine."
"The three clades of I2* separated from each other very long ago compared to their separate coalescence ages. Someday we will have SNPs to separate these clades."

From the Projects very early results Paul Givargidze (Admin Aramaic DNA Project) has kindly prepared the following diagram and tree of the I2* FTDNA 67 marker results.
