Sahara green and populated years ago

(ANSA) - Rome, February 27 - The Sahara was green and populated thousands of years ago, an Italian-led study said Tuesday.
    The study, led by Rome La Sapienza University's Fulvio Cruciani and published in Genome Biology, used an innovative DNA sequencing technique to reconstruct human migration in the area.
    The Sahara was covered in lush vegetation between 12,000 and 5,000 years ago, the study found.
