Subject: [yDNAhgI] Exciting new I2* Clade
Over the last couple days an exciting new, isolated (in both time and geography) clade of I2* has been found.
1) It is funny what excites some of us, and 2) I believe its I2*.
Present count of members consists of 6 Italians, 3 Croats, I Greek, 1 Serbian, and 1 Tyrolean? The clade, itself, looks to be only about 2000 years old to its TMRCA, but this could be biased down because such an isolated clade is likely to be found with its most conforming haplotypes first.
But here's what is so interesting: it's interclade node with other clades of I2* are ancient. Let's call this clade for now I2*-ADR; the I2* project folks may want to use a different clade nickname? Here are interclade node age estimates:
ADR-Arm 12,000 years
ADR-J 15,500 years
ADR-14 12,750 years
ADR-13 12,900 years
ADR-12 14,000 years
Arm stands for Armenian cluster; J stands for Jewish cluster. The estimated TMRCAs for Arm, J, 12, 13, 14 clades are all much, much less than 12,000 years
Ethnic clades J and Arm seem to be affiliated with I2*-14 clade. The J clade is so young it just reaches back to a historic era TMRCA.
Members for this new I2*-ADR were found in ysearch, smgf, ancestry.com, yhrd, and other geographical projects. Just the Greek has snp tests, and they point toward I2* but have not totally closed the deal yet (P38+, P37-, M223-, M253-)
There is a brand new I2* project with gung-ho administrators. I2* seems to be our deepest in time peek into the origins of y haplogroup I due to mainly to its age and pecularities of its geographical distribution in Europe and SW Asia. My own database contains hundreds of I2* haplotypes. Only a small fraction of them have joined the I2* project so far because of the newness of the project. I urge I2* folks to join that project. Some of the benefits are discounts on further STR or SNP tests. Many of these I2* haplotypes I see in my database only have a limited number of STR markers. By expanding to the full 67 plus smgf markers, you could greatly help research into the phylogenetic tree structure of I2* and learn how your line relates to it all.
Here's the address for the I2* project. Join up and let's try to find out where our haplogroup I earliest ancestors were and when?http://www.familytreedna.com/public/I2nosubcladeM170P215/default.aspx
