Key MethodIn order to attain a finer reconstruction of the peopling of southern and central-eastern Europe from the Levant, we determined the frequencies of eight lineages internal to the Y chromosomal haplogroup J, defined by biallelic markers, in 22 population samples obtained with a fine-grained sampling scheme. Our results partially resolve a major multifurcation of lineages within the haplogroup. Analyses of molecular variance show that the area covered by haplogroup J dispersal is characterized by…

Phylogeography of Y chromosomal haplogroups as reporters of Neolithic and post-Neolithic population processes in the Mediterranean area

These analyses seem to resolve the signal of recent post-Neolithic events from the noise of the main East-to-West Palaeolithic/early Neolithic migrations and confirm that, provided an appropriate level of resolution is used, patterns of diversity among chromosomes which originated outside Europe may often be recognized as the result of discontinuous processes which occurred within Europe.

A finely resolved phylogeny of Y chromosome Hg J illuminates the processes of Phoenician and Greek colonizations in the Mediterranean

A geographically structured sampling of seven subclades of haplogroup J in Turkey, Greece and Italy provided strong temporal and distributional evidence for markers of the Greek settlement of Magna Graecia and Phoenician migrations.

Paternal lineages in Libya inferred from Y-chromosome haplogroups.

Overall, the Y-haplogroup diversity in Libya and in North Africa is characterized by two genetic components, typical of Berber-speaking people (E-M81) and originating from Arabic populations (J(xJ1a,J2)-M304), in agreement with the hypothesis of an Arabic expansion from the Middle East, shaping the North African genetic landscape.

Paternal lineages in southern Iberia provide time frames for gene flow from mainland Europe and the Mediterranean world

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.

High-resolution phylogenetic analysis of southeastern Europe traces major episodes of paternal gene flow among Slavic populations.

The extent and nature of southeastern Europe (SEE) paternal genetic contribution to the European genetic landscape were explored based on a high-resolution Y chromosome analysis involving 681 males from seven populations in the region, finding that five major haplogroups comprise more than 70% of SEE total genetic variation.

The peopling of Europe and the cautionary tale of Y chromosome lineage R-M269

Analysis of frequency patterns and diversity in the largest collection of R-M269-related chromosomes yet assembled reveals no geographical trends in diversity, in contradiction to expectation under the Neolithic hypothesis, and suggests an alternative explanation for the apparent cline in diversity recently described.

Y‐chromosome Lineages from Portugal, Madeira and Açores Record Elements of Sephardim and Berber Ancestry

The present composition of the Y chromosomes in Portugal in this haplogroup likely reflects a pre‐Arab component shared with North African populations or testifies, at least in part, to the influence of Sephardic Jews.

Synthetic review on the genetic relatedness between North Africa and Arabia deduced from paternal lineage distributions

Y-chromosome single-nucleotide polymorphisms in the Arab world are drawn to provide an anthropological approach to the analysis of the genetic landscape of these populations, showing an important paternal gene flow from the Middle East towards North Africa.

Paleolithic Y-haplogroup heritage predominates in a Cretan highland plateau

The geographic stratification of the contemporary Cretan Y-chromosome gene pool was assessed by high-resolution haplotyping to investigate the potential imprints of past colonization episodes and the population substructure.



The Human Y Chromosome Haplogroup Tree: Nomenclature and Phylogeography of Its Major Divisions

The recent construction of a highly resolved tree of the nonrecombining portion of the Y chromosome (NRY), and the development of a cladistic nomenclatural system to name the resulting haplogroups support the hypothesis of an African origin of human NRY diversity.

Excavating Y-chromosome haplotype strata in Anatolia

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.

A multistep process for the dispersal of a Y chromosomal lineage in the Mediterranean area.

A microsatellite-defined Y-chromosomal lineage identified by us and reported in previous studies, whose geographic distribution and antiquity appear to be compatible with the Neolithic spread of farmers suggests that its spread was associated to a population expansion, with a high rate of male gene flow in the Turkish-Greek area.

Y chromosomal heritage of Croatian population and its island isolates

High frequency of haplogroup I in Croatian populations and the phylogeographic pattern in its background STR diversity over Europe make Adriatic coast one likely source of the recolonization of Europe following the Last Glacial Maximum.

Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.

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.

The Eurasian Heartland: A continental perspective on Y-chromosome diversity

This study reports the frequencies of 23 Y-chromosome biallelic polymorphism haplotypes in 1,935 men from 49 Eurasian populations, with a particular focus on Central Asia.

A genetic landscape reshaped by recent events: Y-chromosomal insights into central Asia.

Two particularly striking features were seen: an extremely high level of Y-chromosomal differentiation between geographically close populations, accompanied by low diversity within some populations, and the occurrence of several recent bottlenecks or founder events.

High-resolution analysis of human Y-chromosome variation shows a sharp discontinuity and limited gene flow between northwestern Africa and the Iberian Peninsula.

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.
