Synthetic review on the genetic relatedness between North Africa and Arabia deduced from paternal lineage distributions S Triki-Fendri, A Rebai 2014
Abstract
-Y-chromosome single-nucleotide polymorphisms are highly used for phylogenetic construction and in the study of human migration patterns and evolution. Knowing that these genetic markers are associated with certain aspects of human culture like languages, it has been reported that some specific haplogroups characterize the Arab world. In this review, we draw the main conclusions referring to these polymorphisms in the Arab world, in order to provide an anthropological approach to the analysis of the genetic landscape of these populations. In the Middle East, the predominant categories of Y chromosomes are varieties associated with haplogroup J-M304. It has been hypothesized that the center of origin of sub-haplogroup J1-M267 would be the southern Arabian Peninsula whereas J2-M172 seems to be originating from the Fertile Crescent region. In North African populations, the distribution of E-M81, the most common haplogroup there, closely matches the present area of Berber-speaking population’s allocation on the continent, suggesting a close haplogroup-ethnic group parallelism. Remarkably, J1-M267 and J2-M172 were also encountered in North African populations but with less frequency than the Middle Eastern ones, showing an important paternal gene flow from the Middle East towards North Africa. This is in agreement with historical data such as the Phoenician migration flows, from the Fertile Crescent, and mainly to the Arab expansion during the spread of Islam and the important migration of Arabic tribes like the Hilalians that led to a large scale Arabization of North Africa.

Unbelievable that SOME authors still use "frequency" to make their argument, when there are so many more advanced techniques to determine migration routes. Even Henn did NOT use frequency. She used a more "cunning" method ie mathemetical SNP "bottle necking" that took place at the first OOA.

Just remember there's really no field consensus on many different points.

Frequency plus diversity of haplogroup is standard and valid method for suggesting origin of a haplogroup. The area including eastern Turkey and the Zagros and Taurus mountains, has been identified as a likely area of ancient J-M267 diversity

We had this argument already on J1…it is at a stalemate. J1-M267 has either an African, Yemenese or Turkey origin. My money is on African. Why? There are a few marker found in Africa that is not found in Turkey. The Soroqo Island off of Africa/Yemen was NOT included in the study. Recently I found these people have one of the highest diversity of J-M287. My 4 W’s- WHERE did they pull there samples.
Am I ever wrong? My money is on Africa.
But no one has done a truly comprehensive study. But I will off-load J2 on the Turks. Why? Because it is only found in the modern Ottoman Cities/port town in Africa.
Sides, Yemen belongs to Africa.
