It seems possible that I and J are a branch of a separate hominid lineage, perhaps a separate neanderthal lineage that doesn't have a B0006 marker. Since, what we see is that where E1b1b, I, and J, exist, there's very little B0006 marking.
Per Maciamo's analysis, what is evident is that microsattelite frequency is not giving us a descriptive frequency of neanderthal admixture since the sattelites are functioning as a measure of collectively different populations. This is also a problem i pointed out with respect to y-halogroup frequency and varience in attemtping to locate a focal point of a haplogroup's origin. It won't be accurate until a high percentage of the population is tested, and the microsattelites become more representative of geography.
It's also unusual that native americans have such a high neanderthal admixture and east asians have zero. We assume natives are of east asian origin?
I'm also skeptical that B0006 measures neanderthal admixture at all. The focal point of west india is odd.
