First, it's difficult to have a meaningful discussion about an article only you have access to.

I consider myself sacked for not having the link in hand before the referral. Not having a subscription to Nature, i'm peeling back through all of my old crap in search.

Second, you've misunderstood the study. The 50,000 year date for Y-chromosome Adam is not for the origin of Homo sapiens, but for the most recent common ancestor of all male Homo sapiens alive today. There is also a Mitochondrial Eve, the most recent common ancestor of all female Homo sapiens alive today, thought to have lived around 140,000 years ago.
The date of the most recent common ancestor is unrelated to the date of emergence of a new species. The age of Y-chromosome Adam is not the same as the age of the Homo sapien species. And neither is the age of Mitochondrial Eve, obviously not since she has a widely divergent date from Y-chromosome Adam. It would be impossible for females to have become Homo sapiens before males, though I grant it makes lots of sense from other perspectives.

Sharp as always, master P.
I didn't quite round out the point...if this had already been rehashed, i didn't want to waste anyone else's time. I agree with your date for MEve. What stands out to me at this point, in the discussion of the ascent of HSapiens, is a combination of factors. The Y-chromosome study should give us a very careful pause when we consider the timing of the development of modern HSapiens. Moving further, the concentration and abrupt appearance of a host of cultural developments (rapid proliferation and advancement of stone tools, bone/antler carvings and 'jewelry', 'pictorial' art, etc) speak very strongly of an abrupt shift in the cultural and biological makeup of HSapiens.
The other point of the study was simply to reinforce the lack of evidence for interspecie Hominid activity in this era...isolating the abrupt appearance of modern HSapiens.
It's more good, solid paleontology that doesn't support the evo paradigm. Abrupt shifts in the makeup of species or the appearance of species bring you closer to a Creator, not further.
Moreover, do you agree that the genetic diversity among current HSapiens neither resembles what we see among living ape species, nor fits what evolution must predict?
Or, you can just ignore me until i find that !$^!#$!ing link. (damn, i'm Christian...i can't swear! what the hell am i thinking!
