    Oldest DNA from Africa offers clues to mysterious ancient culture

    Oldest DNA from Africa offers clues to mysterious ancient culture

    About 15,000 years ago, in the oldest known cemetery in the world, people buried their dead in sitting positions with beads and animal horns, deep in a cave in what is now Morocco. These people were also found with small, sophisticated stone arrowheads and points, and 20th century archaeologists assumed they were part of an advanced European culture that had migrated across the Mediterranean Sea to North Africa. But now, their ancient DNA—the oldest ever obtained from Africans—shows that these people had no European ancestry. Instead, they were related to both Middle Easterners and sub-Saharan Africans, suggesting that more people were migrating in and out of North Africa than previously believed.

    “The findings are really exciting,” says evolutionary geneticist Sarah Tishkoff of the University of Pennsylvania, who was not part of the work. One big surprise from the DNA, she says, is that it shows that “North Africa has been an important crossroads … for a lot longer than people thought.”


    The origins of the ancient Moroccans, known as the Iberomaurusians because 20th century archaeologists thought they were connected to peoples of the Iberian Peninsula, have been a mystery ever since the Grotte des Pigeons cave was discovered near Oujda, Morocco, in 1908. Starting 22,000 or so years ago, these hunter-gatherers eschewed more primitive Middle Stone Age tools, such as larger blades used on spears, to produce microliths—small pointed bladelets that could be shot farther as projectile points or arrowheads. Similar tools show up earlier in Spain, France, and other parts of Europe, some associated with the famous Gravettian culture, known for its stone figurines of curvaceous women.
