It is a shifting landscape Vince, and no one is certain about anything. No
harm in propounding hypotheses, and even theoretic frameworks bolstered by
data from varied sources. However, even the population geneticists seem
uncertain about the timing of events. Now Michael Hammer has come on board,
along with Peter Underhill some time ago, with Zhivotovsky in terms of
dating clade ages - so multiply by 3.6 - or not. How are genetic
genealogists supposed to have confidence in any one approach when opinions
are so varied and so entrenched. I will sit on the fence but if pressed do
favor a Neolithic expansion of P312 with the rapid emergence of an array of
subclades. I don't disagree with the Western Asian source population. We
will be discussing this matter until ancient DNA or an approach not yet
conceived is able to provide something more definitive. Just the way it is.
