Berber Genetic Identity
The prehistoric populations (Berbers) of Morocco are related to the wider group of Paleo-Mediterranean peoples. The Afroasiatic phylum probably originated in the mesolithic period, perhaps in the context of the Capsian culture.[15][16] DNA analysis has found commonalities between Berber Moroccan populations and those of the Sami people of Scandinavia showing a link dating from around 9,000 years ago.[17] By 5000 BC, the populations of Morocco are an amalgamation of Ibero-Maurisian and a minority of Capsian stock blended with a more recent intrusion associated with the Neolithic revolution.[18] Out of these populations, the proto-Berber tribes form during the Late Paleoltihic Era.[19]

[edit]First settlers
According to the leading evolutionary theory of human origins, known as the Out of Africa theory, anatomically modern humans first emerged in Africa 150,000-200,000 years ago. All non-Africans are descended from at least one group of humans who migrated out of Africa into western Asia 50,000-70,000 years ago. The first modern humans in Europe, the Cro-Magnon, arrived from North-west Africa and are believed to have completely replaced the previous inhabitants, the Neanderthals. Cro-Magnons are known as Ibero-Maurisians or Mechta-Afalou People, they were in Morocco by 45,000 years ago or Probably they were Evolved from The Aterians, the Cro-Magnon people had populated much of North Africa. There was a massive major human migration from Morocco and this paleolithic population was weakly Mixed by later Capsian migrations during the Neolithic Era, this Prehistoric Population still survived and isolated in the Atlas Mountains of Morocco known until our days as Berbers.
[edit]Y-chromosome DNA
Distribution of Y haplotype E-M81 E1b1b1b in North Africa, West Asia and Europe.
Recent studies make clear no significant genetic differences exist between Arabic and non-Arabic speaking populations, The human leukocyte antigen HLA DNA data suggest that most Moroccans are of a Berber origin and that Arabs who invaded North Africa and Spain in the 7th century did not substantially contribute to the gene pool.[20][21] The Muslim refugees from Iberia settled in the coast-towns.[22] According to a 2000 article in European Journal of Human Genetics, Moroccans from North-Western Africa were genetically closer to Iberians than to Sub-Saharan Africans of Bantu Ethnicity and Middle Easterners.[23]
The different loci studied revealed close similarity between the Berbers and other north African groups, mainly with Moroccan Arabic-speakers, which is in accord with the hypothesis that the current Moroccan population has a strong Berber background.[24]
The E1b1b1 clade is presently found in various forms in Morocco. Total E1b1b1 (E-M35) frequencies reached at 93.8% in Moroccans [25]
E1b1b1b1(E-M81), formerly E1b1b1b, E3b1b, and E3b2, is the most common Y chromosome haplogroup in Morocco, dominated by its sub-clade E-M183. This haplogroup reaches a mean frequency of 100% to 50% In North Africa, decreasing in frequency from approximately 85% or more in Moroccan Berber populations, including Saharawis, to approximately 25% to the east of this range in Egypt. Because of its prevalence among these groups and also others such as Mozabite, Riffians, Chleuhs, Middle Atlas, Kabyle and other Berber groups, it is sometimes referred to as a genetic Berber marker.
This phylogenetic tree of The Berber haplogroup subclades is based on the YCC 2008 tree and subsequent published research as summarized by ISOGG.[26][27][28]
E1b1b1b (L19, V257)
E1b1b1b1 (M81)
E1b1b1b1a (M107) Underhill et al. (2000).
E1b1b1b1b (M183) This clade is extremely dominant within E-M81. In fact, while Karafet et al. (2008) continues to describe this as a sub-clade of E-M81, and ISOGG defers to Karafet et al., all data seems to imply that it should actually be considered phylogenetically equivalent to M81[citation needed]
E1b1b1b1b1 (M165) Underhill et al. (2000).
E1b1b1b1b2 (L351) Found in two related participants in The E-M35 Phylogeny Project.
Average North African Moroccan Berbers have frequencies of E3b3 in the +80%. Alvarez et al.(2009) study shows a frequency of E3b1b of 28/33 or 84.8% in Berbers from Marrakesh. With the rest of the frequencies being 1/33=3% E3a*, 1/33=3% E3b*, 1/33 or 3% E3b1a, and 1/33 or 3% E3b1c.[25]
The most basal and rare E-M78* paragroup has been found at lower frequencies in Moroccan Arabs. The sub-clade: E1b1b1a1d (E-V65), is found in high levels in the Maghreb regions of far northern Africa. Cruciani et al. (2007) report levels of about 20% amongst Libyan Arab lineages, and about 30% amongst Morrocan Arabs. It appears to be less common amongst Berbers, but still present in levels of >10%. The authors suggest a North African origin for this lineage. In Europe, only a few individuals were found in Italy and Greece. Capelli et al. (2009) studied the beta cluster in Europe. They found small amounts in Southern Italy, but also traces in Cantabria, Portugal and Galicia, with Cantabria having the highest level in Europe in their study, at 3.1% (5 out of 161 people).
Other frequencies of E1b1b1a1c (E-V22) is reported by Cruciani et al. (2007) include Moroccan Arabs (7.27%, 55 people) and Moroccan Jews (8%, 50 people).

Concerning E-M123 without checking for the E-M34 SNP is found at small frequencies in Morocco A Low regional percentages for E-M123 was reported in Moroccan Berbers around 3%.
