A total of 553 Y‐chromosomes were analyzed from mainland Portugal and the North Atlantic Archipelagos of Açores and Madeira, in order to characterize the genetic composition of their male gene pool. A large majority (78–83% of each population) of the male lineages could be classified as belonging to three basic Y chromosomal haplogroups, R1b, J, and E3b. While R1b, accounting for more than half of the lineages in any of the Portuguese sub‐populations, is a characteristic marker of many… Expand

Y-chromosome lineages in São Tomé e Príncipe and Cabo Verde islands: Different input of European influence
Abstract The Y-chromosome haplogroup composition of the population of Sao Tome e Principe and Cabo Verde Archipelagos was profiled by using 24 biallelic markers, and compared with populations from… Expand
Y‐chromosome variation in South Iberia: Insights into the North African contribution
TLDR
Population of Pedroches Valley, a hypothetical Berber settlement, located in the northwest portion of Córdoba province (Andalusia, Spain), had been analyzed for its Y‐chromosome diversity, showing low levels of North African E3b1b‐M81 haplogroups, which rejects the hypothesis of a gradual genetic assimilation of Berber settlers during the Islamic period. Expand
New insights on intercontinental origins of paternal lineages in Northeast Brazil
TLDR
Analysis of the major Y-chromosome lineages that form the most dynamic migratory region from the Brazilian colonial period suggests that the ongoing entry of European, Middle Eastern, and African males in the Brazilian Northeast was significantly responsible for the present-day genetic architecture of this population. Expand
Paternal lineages in southern Iberia provide time frames for gene flow from mainland Europe and the Mediterranean world
TLDR
The particular Andalusian R1b-M269 assemblage confirms the shallow topology of the clade, and the sharing of lineages with the rest of Europe indicates the impact in Iberia of an amount of pre-existing diversity, with the possible exception of R 1b-DF27. Expand
The African contribution to the present‐day population of the Azores Islands (Portugal): Analysis of the Y chromosome haplogroup E
TLDR
The present‐day representation of sub‐Saharan lineages in Azores, although reduced, is higher than in other Portuguese populations, where the demographic representation ofSub‐Saharan slaves is reported as similar. Expand
The Andalusian population from Huelva reveals a high diversification of Y-DNA paternal lineages from haplogroup E: Identifying human male movements within the Mediterranean space
TLDR
The haplogroup E among Western Andalusians revealed a complex admixture of genetic markers from the Mediterranean space, with interesting signatures of populations from the Middle East and the Balkan Peninsula and a surprisingly low influence by Berber populations compared to other areas of the Iberian Peninsula. Expand
Y chromosome genetic variation in the Italian peninsula is clinal and supports an admixture model for the Mesolithic-Neolithic encounter.
TLDR
The results support a male demic diffusion model, even if population replacement was not complete and the degree of Neolithic admixture with Mesolithic inhabitants was different in different areas of Italy. Expand
Geographical Structure of the Y‐chromosomal Genetic Landscape of the Levant: A coastal‐inland contrast
TLDR
A coastal‐inland, east‐west pattern of diversity and frequency distribution in several haplogroups within the small region of the Levant is found, likely to have arisen mainly from differential migrations, with different lineages introduced from the east and west. Expand
Uniparental Markers of Contemporary Italian Population Reveals Details on Its Pre-Roman Heritage
TLDR
From North to South, Italy shows clinal patterns that were most likely modulated during Neolithic times, although some heterogeneity exists based on different analysis and molecular markers. Expand
From Arabia to Iberia: A Y chromosome perspective.
TLDR
It is proposed that Moriscos' relocations to the north during the Reconquista, the migration of cryptic Muslims seeking refuge in a more lenient society and/or more geographic extensive pre-Islamic incursions may explain the higher frequencies and older time estimates of mutations in the north of the Peninsula.

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
Y chromosomal haplogroup J as a signature of the post-neolithic colonization of Europe
TLDR
Dating estimates confirmed the presence of a major population structuring at the time of spread of haplogroup J in Europe and a punctuation in the peopling of this continent in the post-Neolithic, compatible with the expansion of the Greek world. Expand
Diversity of mtDNA lineages in Portugal: not a genetic edge of European variation
TLDR
It is hypothesised that the recent Black African slave trade could have been the mediator of most of the L sequence inputs, while the population movement associated with the Muslim rule of Iberia has predominantly introduced U6 lineages. Expand
Excavating Y-chromosome haplotype strata in Anatolia
TLDR
This comprehensive characterization of Y-chromosome heritage addresses many multifaceted aspects of Anatolian prehistory, including: the most frequent haplogroup, J, splits into two sub-clades, one of which (J2) shows decreasing variances with increasing latitude, compatible with a northward expansion. Expand
Mitochondrial portraits of the Madeira and Açores archipelagos witness different genetic pools of its settlers
TLDR
A comparison of the genetic composition of these two archipelagos with the Canary Islands, specially taking into account that their European source population was essentially from the Iberian Peninsula, testifies the stronger impact of the North African U6 cluster in the Canaries. Expand
Phylogeographic analysis of haplogroup E3b (E-M215) y chromosomes reveals multiple migratory events within and out of Africa.
TLDR
The present study shows that earlier work based on fewer Y-chromosome markers led to rather simple historical interpretations and highlights the fact that many population-genetic analyses are not robust to a poorly resolved phylogeny and reveals signatures of several distinct processes of migrations and/or recurrent gene flow that occurred in Africa and western Eurasia over the past 25000 years. Expand
High-resolution analysis of human Y-chromosome variation shows a sharp discontinuity and limited gene flow between northwestern Africa and the Iberian Peninsula.
TLDR
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 complete) barrier to gene flow. Expand
Genetic Differentiation of the Cabo Verde Archipelago Population Analysed by STR Polymorphisms
Allele frequencies for 17 STR loci were analyzed in a sample of unrelated males from the Cabo Verde Archipelago. The samples were gathered in such a way that the origin of the subjects was perfectly… Expand
Mitochondrial DNA affinities at the Atlantic fringe of Europe.
TLDR
Mitochondrial DNA analysis of Atlantic European samples has detected significant latitudinal clines for several clusters with Paleolithic and Neolithic coalescence ages in Europe, and it is proposed that a pre-Neolithic origin for this gene flow is proposed. 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
