I am interested in the X Haplotype, of which is descended from the N Haplotype.
What I find curious is the divergence of geographic location, from the N to the X. For example, the origin of the N Haplotype is generally shown in the mideast area, and the emergence of the X descendant is shown in the Scandinavian countries, and in North America in relatively small numbers and specific locations.
But doesn't that also mean that X could have been everywhere in between and just mutated into the modern haplotypes? I am sure I have seen a progression chart... maybe from you...showing earliest haplotypes, progressing to N, progressing to X, etc. It seems to me that X is just a remnant of an ancient strain that was isolated enough not to mutate, but where it wasn't isolated, may have mutated into modern day popular strains.
