News for G2a2b1 persons
Sorry! Last year you were somewhere within the G2a4 group, but the G2a4 category was abolished recently. Because of the confirmation that L223 constitutes a broader super group that includes you and the men of the new G2a2a (M286) and G2a2c (L293) subgroups, your subgroup had to be moved in order to be under L223 in the tree but it remains still under L223's subgroup L91.
The overall L91 subgroup (G2a2b) was involved in the biggest news of 2011 for G persons, namely that the mummified Iceman found in the Italian Alps shares your L91 (G2a2b) mutation. Because he has been relialbly dated to a little over 5000 yrs old, this means that L91 is at least that old. Since L91 is only a tiny fraction of the European population today, this is good evidence that your early L91 cousins in Europe were not too successful in populating the continent though they seem to have brought metal tools and agriculture to Europe from the Near East. The Iceman's nearest relatives are said to be in Sardinia. This provides some evidence also that the L91 men had seafaring skills.
Within the project, the eastern boundaries of the L91 subgroup have been expanded with the addition of a sample from among the Bakhtiari of western Iran. So this tells us L91 has expanded beyond Europe, North Africa and Armenia, as was known earlier.
Two of you are listed as confirmed G2a2b1 by having the L166 and L167 mutations. It is presumed that these mutations are also found in the rest of you with the Kraus surname. No one outside the Kraus family seems to have these mutations, but no one is really close genetically to the Krauses. I leave it up to those involved in Kraus research to determine whether other Krauses should be tested for L166 and L167.
There is actually some possibility that your L166 and L167 subgroup may be abolished officially. Those who make the official charts have tightened the rules. Because of this, SNP mutations found so far only in one family would be carried now as private SNPs and separate from the tree structure. You would then revert to being part of the overall L91 group which is older than your subgroup of L91. We are hoping to get additional testing for L166 and L167 from men outside your family group in hopes of finding someone else who has these.
So, in summary, there are no recommendations at present for additional testing within your subgroup, but those who are researching your family's structure may have reasons to order L166 and L167 for additional persons.
