In the present study we have analyzed 44 Y-chromosome biallelic polymorphisms in population samples from northwestern (NW) Africa and the Iberian Peninsula, which allowed us to place each chromosome unequivocally in a phylogenetic tree based on >150 polymorphisms. The most striking results are that contemporary NW African and Iberian populations were found to have originated from distinctly different patrilineages and that the Strait of Gibraltar seems to have acted as a strong (although not… Expand
Tracing past human male movements in northern/eastern Africa and western Eurasia: new clues from Y-chromosomal haplogroups E-M78 and J-M12.
TLDR
The geographic and quantitative analyses of haplogroup and microsatellite diversity is strongly suggestive of a northeastern African origin of E-M78, with a corridor for bidirectional migrations between northeastern and eastern Africa and trans-Mediterranean migrations directly from northern Africa to Europe. Expand
Phylogeography of Y-chromosome haplogroup I reveals distinct domains of prehistoric gene flow in europe.
TLDR
Haplogroup I, the only major clade of the Y phylogeny that is widespread over Europe but virtually absent elsewhere, is analyzed, in detail, and it is revealed that it underwent a postglacial expansion and marked the human colonization of Sardinia approximately 9,000 years ago. Expand
Reduced genetic structure of the Iberian peninsula revealed by Y-chromosome analysis: implications for population demography
TLDR
The results indicate that neither old or recent Levantine expansions nor North African contacts have influenced the current Iberian Y-chromosome diversity so that geographical patterns can be identified. Expand
A predominantly neolithic origin for Y-chromosomal DNA variation in North Africa.
TLDR
The Neolithic transition in this part of the world was accompanied by demic diffusion of Afro-Asiatic-speaking pastoralists from the Middle East, and it is suggested that the North African pattern of Y-chromosomal variation is largely of Neolithic origin. Expand
Introducing the Algerian Mitochondrial DNA and Y-Chromosome Profiles into the North African Landscape
TLDR
A sample of 240 unrelated subjects from a northwest Algeria cosmopolitan population was analyzed using mtDNA sequences and Y-chromosome biallelic polymorphisms, focusing on the fine dissection of haplogroups E and R, which are the most prevalent in North Africa and Europe respectively. Expand
Y-chromosome and mtDNA polymorphisms in Iraq, a crossroad of the early human dispersal and of post-Neolithic migrations.
TLDR
The different proportion of long-range genetic input observed for the mtDNA and the Y chromosome appears to indicate that events of gene flow to this area might have involved mainly males rather than females. Expand
Y-chromosome E haplogroups: their distribution and implication to the origin of Afro-Asiatic languages and pastoralism
TLDR
The combined analysis of 17 bi-allelic markers in 1214 Y chromosomes together with cultural background of 49 populations displayed in various metrics indicate a major contribution of East African populations to the foundation of the macrohaplogroup, suggesting a diversification that predates the appearance of some cultural traits and the subsequent expansion that is more associated with the cultural and linguistic diversity witnessed today. Expand
Separating the post-Glacial coancestry of European and Asian Y chromosomes within haplogroup R1a
TLDR
The diversity and frequency profiles of M458 suggest its origin during the early Holocene and a subsequent expansion likely related to a number of prehistoric cultural developments in the region, and the virtual absence of M 458 chromosomes outside Europe speaks against substantial patrilineal gene flow from East Europe to Asia, including to India, at least since the mid-Holocene. Expand
A back migration from Asia to sub-Saharan Africa is supported by high-resolution analysis of human Y-chromosome haplotypes.
TLDR
Phylogeographic analyses suggest that a large component of the present Khoisan gene pool is eastern African in origin and that Asia was the source of a back migration to sub-Saharan Africa. Expand
Analysis of Y-chromosome variability and its comparison with mtDNA variability reveals different demographic histories between islands in the Azores Archipelago (Portugal).
TLDR
An assessment of the NRY variability, and its comparison with mitochondrial DNA (mtDNA) variability, was further evidence of the differential composition of males during the settlement of the three groups of islands, contrary to what has been previously deduced for the female settlers using mtDNA data.

Recent male-mediated gene flow over a linguistic barrier in Iberia, suggested by analysis of a Y-chromosomal DNA polymorphism.
TLDR
Evidence for direct or indirect gene flow over the substantial linguistic barrier between the Indo-European and non-Indo-European-speaking populations of the Catalans and the Basques, during the past few thousand years is provided. Expand
Alu insertion polymorphisms in NW Africa and the Iberian Peninsula: evidence for a strong genetic boundary through the Gibraltar Straits
TLDR
Genetic distances and principal component analyses show a clear differentiation of NW African and Iberian groups of samples, suggesting a strong genetic barrier matching the geographical Mediterranean Sea barrier. Expand
Genetic diversity in the Iberian Peninsula determined from mitochondrial sequence analysis
TLDR
The timing of divergence of populations within Iberia points to a shared ancestry of all populations in the Upper Palaeolithic, and lineage diversity comparisons with European and North African populations shows the Iberian Peninsula to be more similar to other European populations, although a small number of Iberians lineages can be traced to North Africa. Expand
Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.
TLDR
These patterns retain a strong signal of expansion from the Near East but also suggest that the demographic history of Europe has been complex and influenced by other major population movements, as well as by linguistic and geographic heterogeneities and the effects of drift. Expand
Mitochondrial DNA analysis of Northwest African populations reveals genetic exchanges with European, Near‐Eastern, and sub‐Saharan populations
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
Population history of north Africa: evidence from classical genetic markers.
TLDR
The most isolated groups (Mauritanians, Tuaregs, and south Algerian Berbers) were the most differentiated and, although no clear structure can be discerned among the different Arab- and Berber-speaking groups, Arab speakers as a whole are closer to Egyptians and Libyans. Expand
Y chromosomal DNA variation and the peopling of Japan.
TLDR
Four loci mapping to the nonrecombining portion of the Y chromosome were genotyped in Japanese populations from Okinawa, the southernmost island of Japan; Shizuoka and Aomori on the main island of Honshu; and a small sample of Taiwanese, confirming the irregular distribution of this polymorphism in Asia. Expand
mtDNA analysis of the Galician population: a genetic edge of European variation
TLDR
The genetic evidence revealed by the analysis of mtDNA shows the Galician population at the edge of a demographic expansion towards Europe from the Middle East, fully compatible with a population expansion model in Europe during the Upper Paleolithic age. Expand
The geographic distribution of human Y chromosome variation.
TLDR
Variation on the nonrecombining portion of the human Y chromosome is examined to investigate human evolution during the last 200,000 years, compatible with a variety of hypotheses, including multiple human migrations and range expansions. Expand
Variation in short tandem repeats is deeply structured by genetic background on the human Y chromosome.
TLDR
Genetic variability appears to be much more structured by lineage than by population, and the deep structure of the genetic variation in old genealogical units (haplogroups) challenges a population-based perspective in the comprehension of human genome diversity. Expand
