The bone has provided the final piece to a project, launched in 2006 by European evolutionary anthropologist Svante Paabo, to use ancient DNA to trace the human odyssey.
In a study published in the journal Nature on Wednesday, a team reports that the bone adds hugely to genetic knowledge of our cousins, the Neanderthals, who died out around 30,000 years ago.
The scientists compared the genome against...
