Scientists have collected DNA from the fossilised eggshells of birds that died hundreds and in some cases thousands of years ago.
The oldest eggshell to yield DNA came from an Australian emu that died around 19,000 years ago. It is the first time that scientists have succeeded in extracting ancient DNA from the fossilised eggshells of a bird.
