High Frequency of Hap IJ in Iran

It is probably not the home, but near to the origins of thsat group. The distribution of IJ lets suppose, that western asia is the region in which IJ developed.

correction west not east to Iran from Afghanistan...

As I said, western Asia is probably the home of IJ, that may include Iran as well. The problem is, that research isn't able to show the exact place of origin and as well not the exact time of origin. Fact is, that till 46k BP the neanderthalians populated western Asia as findings from Shanidar in Northern Iraq let suppose.That means, that modern human populations at that time lived in Africa, on the Arabian peninsula and east of Iraq. The populations east of Iraq carried mainly haplogroup F. The existance of G in Iran e.g. and the caucasus let suppose, that Inner Iran was not the home of H/IJK, but rather the coastal strip. While later H evolved in India, IJ and KLT followed the neanderthalians after 46k.
LT is interesting, because L appears in high frequency in the Indus valley and T is strong in Mesopotamia, southern Iran, parts of Arabia and on the horn of Afrika. IJ appears with it's subgroups I and J later in Europe and western Asia. That let suppose, that IJ was the western group, while KLT was the eastern one.

So I1 isn't indigenous to Europe?

So I is indigenous to Europe, but ultimately came out of Iran where there is a 34% frequency of I and a high number of its maternal halpogroup  pair.  There is also a lot of J2 in Iran.  Considering that J is related to I and I is  viking DNA these must be where the Nordic traits paleontologists assign to both the Iranians such as the Pashtuns and also the Scandinavians.

I was wondering, why you speak about a high percentage of in Iran. You probably quote Nasidze et al. 2004, p.213, who has 34% I* for Iraniana from Teheran. More recent studies like Alshamaly et al. 2009 have for I*= 3.1% and for  I2a = 1%. This study is supported by Regueiro,Spencer Wells and Cadenas, who's data result is between % 1-3 for haplogroup I in Iran.So it is very likely, that Nasidze's result is wrong.

So in Iran there is about 3% I, 22 % J, 16% R1a, 6% R1b, 10% G, 5% E, 4% for L and Q, 2% for N and the rest is distributed among several others (27%).

As I wrote above, IJK belonged to populations in western asia, short before the westmigration of Homo sapiens to Little Asia and Europe. It belonged to other haplogroups in that era F (later G) and H. IJ spread across Little Asia and Arabia and maybe on the Arabian peninsula J differentiated from IJ and I evolved in Europe (or maybe even in Little Asia) and became common in Europe after 20-25ky BP. Here I remained on the balkans widely, because the glacial did not allow a way north into the arctic deserts of middle europe.

The area of balkanic I is as well the area of the first agricultural cultures in europe, old europe, danubian cultures. I1 evolved ca. 5000 years ago on the balkans or even already in Northern germany or danmark. It is not unlikely, that these first I people were people from the Balkan. Maybe they even introduced agriculture in the North with the funnelbeaker culture and therefor were more reproductive. This may explain as well their high percentage in Scandinavia with more than 30%.
