  • A single finger bone found in the Saudi Arabian desert is helping to rewrite the story of when and how modern humans left Africa. Huw Groucutt at the University of Oxford and his colleagues found the finger bone at a site called Al Wusta in what is now the Nefud desert. It is the second bone in from the fingertip. The team recognised the bone as human, and have now confirmed this by comparing it to finger bones of humans, extinct hominins such as Neanderthals, and other primates. Radiometric dating of the bone shows it is at least 85,000 years old.
