We examined internal lineages and haplotype diversity in Portuguese samples belonging to J‐M304 to improve the spatial and temporal understanding of the introduction of this haplogroup in Iberia, using the available knowledge about the phylogeography of its main branches, J1‐M267 and J2‐M172.

Middle eastern genetic legacy in the paternal and maternal gene pools of Chuetas
TLDR
The composition of their uniparentally transmitted lineages demonstrates a remarkable signature of Middle Eastern ancestry—despite some degree of host admixture—confirming Chuetas have retained over the centuries a considerable degree of ancestral genetic signature along with the cultural memory of their Jewish origin.

We analyzed the Y‐chromosome haplogroup diversity in the Kuwaiti population to gain a more complete overview of its genetic landscape.
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.
Micro‐Phylogeographic and Demographic History of Portuguese Male Lineages
TLDR
Haplogroup frequency distributions, Analysis of Molecular Variance (AMOVA) and genetic distance analyses at both Y‐SNP and Y‐STR levels revealed a general genetic homogeneity of Portuguese sub‐populations.
Y‐chromosome Lineages from Portugal, Madeira and Açores Record Elements of Sephardim and Berber Ancestry
TLDR
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.
The population genomics of archaeological transition in west Iberia: Investigation of ancient substructure using imputation and haplotype-based methods
TLDR
Genome-wide imputation of a large dataset of ancient samples enabled sensitive methods for detecting population structure and selection in ancient samples and revealed subtle genetic differentiation between the Portuguese Neolithic and Bronze Age samples suggesting a markedly reduced influx in Iberia compared to other European regions.
Origin, diffusion, and differentiation of Y-chromosome haplogroups E and J: inferences on the neolithization of Europe and later migratory events in the Mediterranean area.
TLDR
The phylogeography of Y-chromosome haplogroups E and J was investigated in >2400 subjects from 29 populations, mainly from Europe and the Mediterranean area but also from Africa and Asia, revealing spatial patterns that are consistent with a Levantine/Anatolian dispersal route to southeastern Europe.
Y-chromosome diversity in central Portugal reveals signatures of ancient maritime expansions.
TLDR
Y-STR analysis revealed in Coimbra district several haplotypes previously associated with ancient maritime Mediterranean expansions that suggest that maritime routes in the first millennium B.C. may have been important for introduction of new male lineages in Central Portugal.
J1-M267 Y lineage marks climate-driven pre-historical human displacements
TLDR
Phylogenetic analyses depicted a new genetic background consistent with climate-driven demographic dynamics occurring during two key phases of human pre-history: the spatial expansion of hunter gatherers in response to the end of the late Pleistocene cooling phases and the displacement of groups of foragers/herders following the mid-Holocene rainfall retreats across the Sahara and Arabia.
Y-chromosomal evidence of the cultural diffusion of agriculture in southeast Europe
TLDR
Balkan Mesolithic foragers with their own autochthonous genetic signatures were destined to become the earliest to adopt farming, when it was subsequently introduced by a cadre of migrating farmers from the Near East.
The emergence of Y-chromosome haplogroup J1e among Arabic-speaking populations
TLDR
The southerly pattern of decreasing expansion time estimates is consistent with the serial drift and founder effect processes, and accordingly J1e parallels the establishment of rain-fed agriculture and semi-nomadic herders throughout the Fertile Crescent.
