Well what if I2A dinaric appeared in Carpathians and Dinaric Alps,from a mutation from another I2 ?
I mean Ken Nortvedt is saying that I2A dinaric is pretty young.
I understood that some Y DNA tests found a large variety of I2A dinaric in these two places mentioned above.
"Former I2a2a in the Y2010 tree. I2a1b1 (L69.2(=T)/S163.2) is typical of the South Slavic populations of south-eastern Europe, being highest in Bosnia-Herzegovina (>50%). Haplogroup I2a1b1 is also commonly found in north-eastern Italians. There is also a high concentration of I2a2a in north-east Romania, Moldova and western Ukraine. In 2010 has Ken Nordtvedt argued that I2a1b1 is too young not to have been a result of a sudden expansion. According to him I2a1b1 arose not earlier than 2500 years ago in Eastern Europe.
He has presumed this to be a consequence from the Slavic invasion of the Balkans, from the area north-east of the Carpathians since 500 CE. In 2011 Nordtvedt has confirmed I2a1b1 is not older than 2,800 years.
In his last comments about Haplogroup I tree and the conjectured spread map, he locates the start of the I2a1b1 lineage around the middle course of the Vistula."
(according to

I am not agreeing with the part written with italic,those are just supositions,but what is told above with the age of I2A dinaric I think it can be proved scientifically.
Now if you wonder from where the I2 from which I2A dinaric appeared by some mutation is,no ideea,but I doubt is from sarmatians or slavs.
