Hi all,

Just posted a paper online:it is meant as a sort of "Getting started genography" and covers the history of I2a2b-L38 and also that of its brother clade I2a2a-M223.
As you will notice the paper relies heavily on YFull data: https://sites.google.com/site/haplogroupil38/19-getting-started-with-i-l38
Comments are welcome ;)

Best wishes,

Hans De Beule

This is fantastic. I've noticed some similarities in distribution patterns between my branch of I2c (I think it's called I2c1a2 now, used to be I2c-"A") and I2-L38, so it's great to see such a good summary of I2-L38. I'd be fascinated to read your opinion of the distribution of other I2 subclades as well. Care to tackle I2c2? That one is bizarre, popping up in your summary by placing second in your "Table 6: The ten I2-branches with the largest delta between formation and TMRCA, in descending order," and also, as you note, popping up in Motala, Sweden 7,500+ years ago, long before its modern TMRCA. I2c2 also has a modern distribution with a big expansion among Armenians, Georgians, etc. for good measure.

Hi Sparkey. I not very little about the distribution of I2c. Will take a look at it.
Best,
Hans

Why do you believe these two haplogroups never took a strong foothold in any one particular area?
