Origins of I2a1: Is it Slavic?

[reboun]

As far as I know, it is of Slavic origin but its existence in Sardinia makes me question my knowledge since Sardinians have almost no Slavic ancestry. What is the origin of I2a1 haplogroup?

[Dick]

Depends on the subclade. The reason for such a high percentage on Sardinia is during the last Ice age the sea levels dropped so low that the distance between Sardinia and the mainland was reduced which made crossing relatively easy. After the sea levels rose again, those cromags were stuck on the island like Gilligan.

Then came the farmer women on boats and made them their sex slaves.

yes, originally Slavic, I read a few years ago that one day Germans (R1a) started call themself Slavs, Celts (R1b) - as Germanics, and real Slavs (I2a1) ran/escaped down/south, and that's very true...
next question?!
