It spread around 2000 years ago period when Germanic tribes were invading Rome and migrating (I2 comes from Ostrogoths, Vandals etc..) thats why people with I2 are tall like Scandinavians and are not short like Slavs. And in countries that don't have much north African E1b and alot I2 like Slovenia and Croatia people there have colored eyes also and more Germanic look and not slavic. Even the name says I2 from Germanic I1
