Scientists find oldest life form ever discovered - bacteria that smell like rotten eggs

Scientists have discovered what they believe to be the oldest complete example of life on earth - but the ancient creature would have smelled strongly of rotten eggs.

The remains were discovered by American scientists from Old Dominion University, in a lump of Sandstone in Western Australia.

The ancient microbes are thought to have been either purple or brown in colour - and very smelly.

Boffins think the foul smelling colonies of bacteria may have used their sulphuric stench to communicate with each other.

Geobiologist Nora Noffke said: "Life 3.5 billion years ago was not that simple, it was already quite highly developed."
