Scientists say ancient viruses inherited from Neanderthals have been found in modern human DNA.
Researchers at Oxford University's Department of Zoology are looking at possible links between the retroviruses, which are hard-wired into our DNA, and modern diseases such as Aids and cancer.
Around 8% of human DNA is made up of such retroviruses, which are passed from generation to generation.
It is thought they may have originated from an ancestor common to both Neanderthals and early humans more than half a million years ago.
