Scientists claim to have discovered fossils of some living things thought to have appeared on Earth about 4 billion years ago.
BBC said the small tube-like structures discovered by scientists at University College London (UK) on the rocks in Quebec, Canada. They argue that this may be the earliest evidence of life appearing on Earth.

In the work published in Nature, scientists believe these objects could be formed from about 3.77 billion to 4.28 billion years ago.
These structures are smaller than the diameter of the hair, are not visible to the naked eye and contain a significant amount of haematie (an iron oxide compound).
It is thought to be a remnant of a bacterium that grew in water, around hydrothermal vents and based on chemical reactions to accumulate iron as energy.

Researchers believe that these fossils may be evidence that opens up a view of the origin of life on Earth.
"If fossils from these cliffs are actually 4.28 billion years ago, we will soon know how life evolved after the ocean formed 4.4 billion years ago , " said the researcher. save Matthew Dodd, the author's group representative, said.
