What’s up with this blob of R1b in the middle of Africa, centered along the Nigeria-Cameroon border on the Adamawa Plateau, at the headwaters of the Benue River and south west of Lake Chad?
>>
R1b came from Africa
Western Europeans are actually Central African

This. West Europeans are shitskins.

Agriculture reached North Africa before the Sahara was fully desert, and there were presumably corridors of lush land between small bodies of water
A tribe probably headed southwards and settled around Lake Chad, eventually becoming absorbed into the local Negroid populace

>R1b1c is found in northern Cameroon in west central Africa at a very high frequency, where it is considered to be caused by a pre-Islamic movement of people from Eurasia

>We observed a decline in heterozygosity in admixed Africans and found that the Eurasian admixture can bias inferences on their coalescent history and confound genetic signals from adaptation and archaic introgression.

>We found evidence of early Eurasian backflow to Africa in people speaking the unclassified isolate Laal language in southern Chad and estimate from linkage-disequilibrium decay that this occurred 4,750–7,200 years ago. It brought to Africa a Y chromosome lineage (R1b-V88) whose closest relatives are widespread in present-day Eurasia; we estimate from sequence data that the Chad R1b-V88 Y chromosomes coalesced 5,700–7,300 years ago. This migration could thus have originated among Near Eastern farmers during the African Humid Period. We also found that the previously documented Eurasian backflow into Africa, which occurred ∼3,000 years ago and was thought to be mostly limited to East Africa, had a more westward impact affecting populations in northern Chad, such as the Toubou, who have 20%–30% Eurasian ancestry today.

"No."

Does this mean that R1A are the Aryans while R1b are the Bantus ?

Yes, we're big black R1bulls

I think you mean R1b1b1c m8.

This website depresses me.

Look, all out-of-Africa haplogroups can be generalized into either DE or CF. DE mutated near Africa and E immediately back-migrated into the continent (D ended up in Asia) and CF mutated in India to spread out to the rest of the world from there. The instances of T, J, and R1b in Africa are from back-migrations.

inaccurate, weren't all those groups centered around India ~50,000 years ago?
>>

Western Europeans are niggers

Yes you.

>>3382552
To be a R1b you have to love cattle and ride horses, or at least having a tradition about that.
Infighting for petty things it's another common trait.
>>
>>3382552
It's most likely the result of a Eurasian back migration several thousand years ago. The variant they carry is called r1b-v88 which is more common in Africa and has a tmcra of around 9-4000 b.c iirc.
