Sá, Luísa; Almeida, Mafalda; Azonbakin, Simon; Matos, Erica; Franco-Duarte, Ricardo; Gómez-Carballa, Alberto; Salas, Antonio; Laleye, AnatóleDespite the importance of ancient DNA for understanding human prehistoric dispersals, poor survival means that data remain sparse for many areas in the tropics, including in Africa. In such instances, analysis of contemporary genomes remains invaluable. One promising approach is founder analysis, which identifies and dates migration events in non-recombining systems. However, it has yet to be fully exploited as...
Biomolecular insights into North African-related ancestry, mobility and diet in...
Silva, Marina; Oteo-García, Gonzalo; Martiniano, Rui; Guimarães, João; von Tersch, Matthew; Madour, Ali; Shoeib, Tarek; Fichera, AlessandroHistorical records document medieval immigration from North Africa to Iberia to create Islamic al-Andalus. Here, we present a low-coverage genome of an eleventh century CE man buried in an Islamic necropolis in Segorbe, near Valencia, Spain. Uniparental lineages indicate North African ancestry, but at the autosomal level he displays a mosaic of North African and European-like ancestries, distinct from any prese...
Mapping human dispersals into the Horn of Africa from Arabian Ice Age refugia u...
Gandini, Francesca; Achilli, Alessandro; Pala, Maria; Bodner, Martin; Brandini, Stefania; Huber, Gabriela; Egyed, Balazs; Ferretti, LucaRare mitochondrial lineages with relict distributions can sometimes be disproportionately informative about deep events in human prehistory. We have studied one such lineage, haplogroup R0a, which uniquely is most frequent in Arabia and the Horn of Africa, but is distributed much more widely, from Europe to India. We conclude that: (1) the lineage ancestral to R0a is more ancient than previously thought, with a...
