DNA analysis of a 7,000 year-old cave-dwelling human skeleton from north Spain revealed what surprising genetic feature?
Light skin radiation, they developed light skin pigmentation as an evolutionary selection acting against vitamin D depletion. Based on ancient DNA analysis conducted in 2014 on human skeletal remains from western Europe, this change from dark to light skin pigmentation likely occurred only recently for at least some Europeans. Paleogenomics researcher Carles Lalueza-Fox of the Pompeu Fabra University in Spain and his colleagues observed that a 7,000-year-old hunter-gatherer from the La Braña-Arintero labyrinthine cave in the Cantabrian Mountains (León, Spain) possessed the allele for blue eyes but not the European mutations for lighter skin pigmentation. Humans with light skin pigmentation have skin
Genetic history of North Africa fossils excavated in Punta Azul, El Hierro, Canary Islands, which are dated to the 10th century. Maternally, the specimens all belong to the H1 clade. These locally born individuals carried the H1-16260 haplotype, which is exclusive to the Canary Islands and Algeria. Analysis of their autosomal STRs indicates that they were most closely related to Moroccan Berbers. In 2018, DNA analysis of Later Stone Age individuals from the site of Taforalt (Iberomaurusian, 15 000 BP) and Early Neolithic Moroccans from the site of Ifri N' Ammar (7 000 BP) revealed that they were related to the modern North Africans and
