A draft of the Y-chromosome phylogeny, including the newly discovered basal A00 clade has been posted by FTDNA. Hopefully some progress can be made in the F portion of the tree, where currently there are subclades F1,F2,F3,G,H, and IJK. Determination of the bifurcation structure within F will doubtlessly be instrumental in informing our understanding of the dispersal of F descendants, which, according to the age of this major Eurasian haplogroup, are closely linked to the Upper Paleolithic event in Eurasia.
Investing in whole-genome sequencing of one individual from each of these clades would be very helpful in determining this structure. Of course, there are already the Complete Genomics data which include haplogroup G and various IJK descendants, so we now need to identify some F1,F2,F3, and H samples and give them the WGS treatment.
