HUDDERSFIELD, ENGLAND—It had been thought that modern humans settled in southern Arabia with the development of agriculture, but a new genetic study by Francesca Gandini of the University of Huddersfield and colleagues suggests that people lived there some 20,000 years ago, during the last Ice Age. According to a report in Sci-News, the researchers focused on a rare mitochondrial DNA lineage (R0a) that is found most frequently in Arabia and the Horn of Africa. They think this lineage is older than had been previously believed, and that when the Ice Age ended some 11,000 years ago, people migrated out of Arabia and into eastern Africa, through the Middle East, and into Europe. For more, go to "New Evidence for Mankind's Earliest Migrations."
