When an ancient-DNA expert gave his colleague a sample of a 40,000-year-old human finger bone from a Siberian cave, he had only one question: Was its mitochondrial DNA that of a Neandertal or a modern human? It was neither. The evolutionary geneticists have apparently identified a new lineage of ancient human, the first time that this has been done using ancient DNA and not fossil bones.
