Jaw belonged to 'oldest Briton'

Scientists have re-assessed a jawbone found at Kents Cavern in Torquay, UK, in 1927.

They have established that the specimen belonged to a modern human - Homo sapiens.

The age of the jawbone, about 42,500 years old, makes it the oldest evidence of modern humans in northwest Europe.

The study author, Dr Tom Higham from Oxford University, explained to BBC Science in Action presenter Jon Stewart how his team arrived at the new age.
