Biomolecular insights into North African-related ancestry, mobility and diet in eleventh-century Al-Andalus
Abstract Historical 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 ances...
