John and Greg,
I'm going to cop-out and quote my own words (see above) to end my part in
this discussion. I brought up Toba yesterday just to suggest an explanation
for the 60,000 year BP date when the 'out of Africa hypothesis' and the
modern human Y coincide. Today I was asked for a reference for the Toba
information and in providing it, I was somehow transposed into a defender of
Ambrose and the Toba Theory of Mass Extinction. That is not the right place
for me and if it was, I just don't have time to defend someone's theory.
I just got my 25 marker upgrade results back from FTDNA. My cousin and I
matched 11/12 on a 12 marker test, with a two step mutation at DYS 388. The
25 marker upgrade showed we still match on everything except DYS 388. Now we
are 24/25 through 7 transmission events.
