They are represented by tiny filaments, knobs and tubes in Canadian rocks dated to be up to 4.28 billion years old.
That is a time not long after the planet’s formation and hundreds of millions of years before what is currently accepted as evidence for the most ancient life yet found on Earth.
The researchers report their investigation in the journal Nature.
As with all such claims about ancient life, the study is contentious. But the team believes it can answer any doubts.
The scientists’ putative microbes from Quebec are one-tenth the width of a human hair and contain significant quantities of haematite – a form of iron oxide or “rust”.
Matthew Dodd, who analysed the structures at University College London, UK, claimed the discovery would shed new light on the origins of life.
“This discovery answers the biggest questions mankind has asked itself – which are: where do we come from and why we are here?

Now, a team of Berkeley-based scientists are suggesting a sort of compromise, and one based on facts and data rather than attempts to smooth over tensions. According to a recent study that will soon be published in Science, researchers suggest that the asteroid impact may have accelerated the volcano explosions, and the combined fallout from both catastrophes may have been what ultimately drove the dinosaurs extinct. It’s even possible that the asteroid impact on its own would not have been powerful enough to wipe out the dinosaurs.
Mark Dyble, the leading anthropologist on the study at University College London, said: “There is still this wider perception that hunter-gatherers are more macho or male-dominated. We’d argue it was only with the emergence of agriculture, when people could start to accumulate resources, that inequality emerged.”..
