Susan, That is really a question for Dr. Jim Wilson.T hat is what his results are showing. I don't know how widespread the tesitng has been. He might (he does) have access to more data than just our Chromo 2 orders. Still, phylogenetic equivalency is only a state as of a point in time. It only takes one new test to come in to attest one of the SNPs is older or younger. However, the whole concepts of bottlenecks in paternal lineages seems to apply well so we should expect to find a number of branches on the Y DNA tree with multiple SNPs marking them.
