Last-stand Neanderthals queried

We may need to look again at the idea that a late Neanderthal population existed in southern Spain as recently as 35,000 years ago, a study suggests.

Scientists using a "more reliable" form of radiocarbon dating have re-assessed fossils from the region and found them to be far older than anyone thought.

The work appears in the journal PNAS.

Its results have implications for when and where we - modern humans - might have co-existed with our evolutionary "cousins", the Neanderthals.
