So far the Z series snps from 1000 Genomes have divided I1xL22 into five divisions: 1) Z58+ Z140+ 2) Z58+ 3) Z58+ Z139+ 4) Z63+ 5) negative for all Z snps So far the branch Z131+ claimed by 1000 Genomes has not bee found. Robust hunks of I1xL22 have fallen in each category. All these branch divisions seem to have happened more than 3000 years ago. The previously known clades of I1xL22 go cleanly with the different snp tagged branches. Some new superclades are emerging from the mist. I1-ASgenerics seem to be trickling along with each division. There are a number of additional Z series snps for the I1xL22 sector which could divide things even more, but FTDNA has not put them in their catalog. Testing has been on the light side; generics probably should do more testing. See “tree for I1” at http://knordtvedt.home.bresnan.net
