Open AccessUnderstanding the genomic heterogeneity of North African Imazighen: from broad to microgeographical perspectives
The strategic location of North Africa has led to cultural and demographic shifts, sha** its genetic structure. Historical migrations brought different genetic components that are evident in present-day Nort...

Open AccessWhole mitogenomes reveal that NW Africa has acted both as a source and a destination for multiple human movements
Despite being enclosed between the Mediterranean Sea and the Sahara Desert, North Africa has been the scenario of multiple human migrations that have shaped the genetic structure of its present-day populations...

Open AccessY-chromosome target enrichment reveals rapid expansion of haplogroup R1b-DF27 in Iberia during the Bronze Age transition
The Y chromosome can yield a unique perspective into the study of human demographic history. However, due to the repetitive nature of part of its sequence, only a small set of regions are suitable for variant ...

Open AccessFounder lineages in the Iberian Roma mitogenomes recapitulate the Roma diaspora and show the effects of demographic bottlenecks
The Roma are the largest ethnic minority in Europe. With a Northwestern Indian origin around ~ 1.5 kya, they travelled throughout West Asia until their arrival in Europe around the eleventh century CE. Their d...

Open AccessWhole-exome analysis in Tunisian Imazighen and Arabs shows the impact of demography in functional variation
Human populations are genetically affected by their demographic history, which shapes the distribution of their functional genomic variation. However, the genetic impact of recent demography is debated. This i...

Open AccessAncient DNA of Phoenician remains indicates discontinuity in the settlement history of Ibiza
Ibiza was permanently settled around the 7th century BCE by founders arriving from west Phoenicia. The founding population grew significantly and reached its height during the 4th century BCE. We obtained nine co...

Open AccessWhole Y-chromosome sequences reveal an extremely recent origin of the most common North African paternal lineage E-M183 (M81)
E-M183 (E-M81) is the most frequent paternal lineage in North Africa and thus it must be considered to explore past historical and demographical processes. Here, by using whole Y chromosome sequences from 32 N...

Open AccessAnalysis of the R1b-DF27 haplogroup shows that a large fraction of Iberian Y-chromosome lineages originated recently in situ
Haplogroup R1b-M269 comprises most Western European Y chromosomes; of its main branches, R1b-DF27 is by far the least known, and it appears to be highly prevalent only in Iberia. We have genotyped 1072 R1b-DF2...
