As I understand, Big Y is the definitive SNP confirmation stage, every Y STR testing are relatively meaningless without SNP verification and I've seen some posts on here how the halopgroup changed after performing the Big Y. Does anyone know how many persons have tested for the Big Y?
Also how many people will need to be tested in order to get a closer look to European map for, say 2000 years ago. From what I've read the estimated population in Europe at the time was around 50 million, so approximately 25 million men from which not all of them Y-DNA lines survived till now so lets say there are 10 million unique terminal SNPs from 2000 years ago which have at least 1 descendant living nowdays. With every mutation occurring every 90-120 years, does that mean there should be around 200 million final deepest subclades today in Europe alone?
More to the point, I understand experts can accurately claim the movement of people with accuracy for 10,000-6,000 years ago, but how many people need to be tested to know with at least 50% accuracy the movement map for Europe? From Eastern Europe especially since in the Dacian zone there will be very few people testing for Big Y and that area was the centre of major population movement in ancient times so without more people testing in that area how will there ever, or in a timely manner of say in our lifetime, determine the population migration routes from 2000 years ago or earlier.
