The latest Z series snp test results are incorporated into “Tree for I1” pdf file at http://knordtvedt.home.bresnan.net Those historic STR-based clades which now have snp tags are shown on the tree as present evidence best suggests. Almost all the new branches of the I1 tree established from the Z snps will also include some previously I1* generics which now become generics of the new downstream subhaplogroups. The L338 branch is an interesting exception. After a couple years of extension testin of L338, every L338+ can comfortably be assigned to AS1 or AS8 --- no exceptions. The ancestral branch line leading to AS1 and AS8 must have been extremely pruned of any branches through extinctions over many centuries prior to the MRCA of AS1/AS8. You can see from the various red vertical lines in the tree, that many of the nodes have been time estimated using interclade variances. The arrowheads generally indicate the individual clade tmrca estimates using intraclade variances. Next batch of Z series snp results will most likely lead to additional tweaking or branch addons to the tree --- especially with regard to he upstream DF29 snp location. Ken
