Eddie Izzard: 'I'm 2.8% Neanderthal'

20 February 2013 Last updated at 00:37 GMT

While using comedian Eddie Izzard's DNA to trace the migration of his ancestors out of Africa and into Europe, geneticist Dr Jim Wilson has discovered that Izzard is 2.8% Neanderthal. This means he has more Neanderthal genes than most people.

In 2010 scientists made a discovery that all human populations that spread out of Africa have a small amount of Neanderthal DNA in them.

A simple saliva swab and the latest DNA science are helping Eddie Izzard explore the secrets of his family history.
