Population Genetics

Shomarka Keita, a biological anthropologist from Howard University, has claimed that populations in Carthage circa 200 BC and northern Algeria 1500 BC were very diverse. As a group, they plotted closest to the populations of Northern Egypt and intermediate to Northern Europeans and tropical Africans. Keita claimed that "the data supported the comments from ancient authors observed by classicists: everything from fair-skinned blonds to peoples who were dark-skinned 'Ethiopian' or part Ethiopian in appearance." Modern evidence showed a similar diversity among present North Africans. Moreover, this "diversity" of phenotypes and peoples was probably due to in situ differentiation, not foreign influxes. Of course foreign influxes certainly had an impact but they did not replace the indigenous Berber population.

The Y chromosome p49a,f TaqI Haplotype V, which corresponds to Y haplogroup (M81)(M2) —formerly E3b1b, E3b2 and colloquially referred to as the "Berber marker" along with E1b1a— has been found among 68.9% of modern Berbers in North Africa and as high as 80% in one group. It is believed to be about 5,600 years old, and to have arrived with the Neolithic expansion from the Near East. M81 is not found in Sub-Saharan Africa. This haplotype has also been observed in as high as 40% of one small group of Andalusians tested. Generally it appears at much lower frequencies among Iberian populations, and lower as distance from North Africa increases.

Y DNA haplogroup E1b1b (formerly E3b) predominates among North African populations; its E1b1b1b subgroup (M81) is identified especially with Berbers. The Vb subtype of p49a,f Haplotype V, apparently corresponding to E3b1b, has been found to occur in two-thirds of the Haplotype V Southern Iberians, that is, in about a quarter of all Andalusians tested. The frequency of Vb is at its highest among Berbers, and was found to decline rapidly from West to East among North Africans sampled. It is uncommon in France and Italy.

A 2006 mitochondrial DNA study of 12th to 13th century Islamic remains from Priego de Córdoba, Spain, indicates a higher proportion (4%) of sub-Saharan African lineages. This is attributed only partially to the period of Moorish occupation; researchers believe that more ancient migrations from Africa to Europe were more significant.
