Indigenous North Africans are genetically quite distinct from sub-Saharan Africans ([1][1]), and this difference is reflected in their lighter skin and European/Middle Eastern physical features. We have previously suggested, on the basis of the distribution of mtDNA type M1, that North Africans are 
Moroccan mitochondrial genetic background suggests prehistoric human migrations across the Gibraltar Strait.
TLDR
After analyzing samples from North Morocco to Spain, it is shown that three fourths of the Moroccan individuals belong to Western Eurasian haplogroups and the frequencies of these are much more similar to those of the Iberian Peninsula than to Those of the Middle East. Expand
A genetic perspective on African prehistory
TLDR
This work discusses the possible origin of modern humans in southern, eastern or Central Africa; the possibility of a migration from southern to eastern Africa more than 100 ka, carrying lineages within mt DNA haplogroup L0; the evidence for a climate-change-mediated population expansion in eastern Africa involving mtDNA haplogroups L3, leading to the “out-of-Africa” migration.

Variación genética del mtDNA: De la genética poblacional a la farmacogenómica
TLDR
After analyzing samples from North Morocco to Spain, it is shown that three fourths of the Moroccan individuals belong to Western Eurasian haplogroups and the frequencies of these are much more similar to those of the Iberian Peninsula than to Those of the Middle East. Expand
High-resolution characterization of genetic markers in the Arabian Peninsula and Near East
In this work, I analysed the maternally transmitted mtDNA and biparentally inherited genome-wide polymorphisms to shed light on successive migrations into and from the Arabian Peninsula, at theExpand
Divorcing the Late Upper Palaeolithic demographic histories of mtDNA haplogroups M1 and U6 in Africa
TLDR
High-resolution phylogenetic dissection of both haplogroups and coalescent time assessments suggest that the extant main branching pattern of both Haplogroups arose and diversified in the mid-later Upper Palaeolithic, with some sub-clades concomitantly with the expansion of the Iberomaurusian industry.

Terminal Pleistocene lithic variability in the Western Negev (Israel): Is there any evidence for contacts with the Nile Valley?
At the end of the Pleistocene (25,000-15,000 BP), there is a shift to more arid conditions in the Negev and the Sinai corresponding to the Last Glacial Maximum. For the Nile Valley and the Levant,Expand
Challenges to Analysis of Ancestral Inference Using Mitochondrial DNA Hypervariable Region 1 SNP Typing
Current analyses of mtDNA with respect to Hispanics/Latinos and persons of African descent are underrepresented and researchers continue to lump them into monomorphic groups. Africans possess theExpand
The Genetic Structure and History of Africans and African Americans
TLDR
A detailed genetic analysis of most major groups of African populations is provided, suggesting that Africans represent 14 ancestral populations that correlate with self-described ethnicity and shared cultural and/or linguistic properties. Expand
African genetic diversity: implications for human demographic history, modern human origins, and complex disease mapping.
TLDR
This review summarizes patterns and the evolutionary origins of genetic diversity present in African populations, as well as their implications for the mapping of complex traits, including disease susceptibility. Expand
Following Pleistocene road signs of human dispersals across Eurasia
The present paper is an endeavor to summarize the evidence for various dispersals of hominins into Eurasia, while avoiding the commonly held assumptions that these events, whether short orExpand

TLDR
A certain mtDNA motif (16172C, 16219G), previously found in Algerian Berbers at high frequency, is apparently omnipresent in Northwest Africa and may reflect regional continuity of more than 20000 years. Expand
