Genetic researchers apparently believe that great genetic diversity within a population in a given area indicates that that area was a point of origin for that population. I strongly disagree. In fact, I believe that this notion has led genetic researchers to interpret the movements of genetic groups in an altogether backwards fashion. An important result of this backwards thinking is the idea that all of the descendants of Y-DNA haplogroup K, including haplogroups N, O and R, originated in eastern or southern Asia. And of course, I have reason to wonder if this isn’t intentional…

The way I see it, great genetic diversity within a population in a given area indicates that that area is a peripheral area rather than a core area. It seems to me that genetic innovations usually occur in core areas and subsequently expand outwards from that core area. This causes all previous genetic groups to move outwards. This results in the genetic innovation dominating the core area, while the periphery becomes increasingly populated by a diverse assortment of genetic groups that had previously existed.

{The observations in the previous two paragraphs relate particularly to the movements of Y-DNA haplogroups; they are not valid with respect to the distribution of mtDNA haplogroups. The reason for this is simply the inherent natural difference between men and women with respect to territoriality.

Males are naturally inclined to expel all unrelated males from their territories, thereby tending to eliminate the possibility of Y-DNA diversity within their territories, and this is just as true on the level of entire haplogroups as on more localized levels (e.g. clans). On the other hand, females are not so inclined to eliminate other mtDNA haplogroups from their territories, thereby allowing for the accumulation of mtDNA diversity.

The natural male propensity to enforce territoriality necessarily means that the existence of Y-DNA diversity in a region must indicate a peripheral area rather than a core area.}

Here is a diagram that attempts to demonstrate the way I see this.

This being said, here are some maps that show how I see the development and movements of the Y-DNA haplogroups in Eurasia.

The following 11 maps represent an attempt at showing the origins and movements of Y-DNA haplogroups in Eurasia. I must stress that these maps are largely my own guesswork. I should also add that Wikipedia was practically the only source of information that I used.

Please note that only the main center of each haplogroup is generally indicated and that expansions from these main centers generally are not indicated.

Also note that haplogroups C, F and H are no longer shown after map 7.

I have attempted to guess approximate dates for these maps. The guess for the first map is approximately 80000 years ago and the guess for the last map is approximately 30000 years ago, the maps in between being at approximately 5000-year intervals.
