If genetics can explain the differences and similitudes among

The chadic languages were spread by middle-eastern migrants. The particular r1b clade they belong to is a middle-eastern one.

I know this post will be flamed by afrocentrics.

Distinctions are 100% artificial.

Depending how deep you go and which ones you choose, you can get groupings of any regions you want.

Want to group only Finland and North Korea? You can.

Because haplomemes are not used for establish the genetic distance between different populations, that's autosomal DNA is for

So what do Y DNA markers provide?

R1B V88 are basically white who conquerred a part of Africa and mixed with the blacks
R1B-M269 is white who remained in Eurasia and didn't move in Africa.

Gives info to some degree about migrations. As the other guy said before what you should be looking at is autosomal DNA in determining genetic closeness. You can be for example haplogroup Q (common Siberia and American natives) but autosomally be indistinguishable from an average German.

Y-DNA never recombines, and doesn't have any affect on physical appearance.

>Western Africans and Western Europeans don't look the same

that map shows the predominance of the R1b Y chromosome marker.

Y chromosome.
