Ancient R1b1 gems

[A_Wode]

I know Humanist/handschar has posted some great topics on R1b in the old DNA Forums. I can't seem to find a thread for this here, but thought it would be fitting to create one.

Over some of my (very basic) research, there are a couple sets of data I would like to share.

Currently 44% of the Kanem descent men belong to R1b1c-V88 - at least I am very certain this is the case.

A very brief overview of Kanem from Wikipedia's Kanem Bornu page.

"The origins of Kanem Empire are very unclear. Until today, historiographical debates oppose the followers of a foundation of Kanem-Bornu by populations from the ancient Near East and followers of a more local development. Some researches try to connect the creation of Kanem-Bornu with exodus from the collapsed Assyrian Empire c. 600 BC to the northeast of Lake Chad.[2] The intensity of scholar discussions around this theory proves that the question haven't been solved yet, and we must be very cautious concerning early formation of Kanem-Bornu[3]."

Of course this origin is up for discussion but I think we'd be hard pressed to consider a Central African origin of R1b - current evidence does point to somewhere in Asia, and I feel a back migration to Africa from the Levant is strong. Coupled with strong papers from Wood, this only supports the case further.

Second, doing a bit of research on YHRD it seems a small sample n=64 of Sudanese Bedouins might be 25% R1b1c. I can't seem to find the study that these are associated with, but it appears they likely belong to this group - a second possibly being T1. Unfortunately, DYS449 wasn't tested to make a stronger prediction.

Possibly I misremember, but it seems rms2 said that this haplotype is only found in Africa?  It was when I suggested a western out of africa migration for R1b?

This is incorrect.  rms2 said that it is not the oldest R1b.  What about multiple migrations out of africa?

I believe it's found in Africa, Levant (Jordan, Syria, Lebanon), Yemen, and Saudi Arabia.

It is not the oldest, which is exactly why I suggested a back-migration from Asia somewhere - but it could still be pretty near close.

No, it's not found only in Africa. It is also found in SW Asia, where I believe it is older. R-V88 is P297-, whereas most of the rest of R1b (R-V88 and R-M335 are the exceptions) is P297+.

It is extremely unlikely that R1b originated in Africa. As I mentioned before, all its closest genetic relatives are found in Asia: K, L, M, N, O, P, Q, R1, R1a, various forms of R1b, and R2 (the Super K Family).
