Every day, scientists are discovering new things that give us information about Earth from the past. Recently, one of these discoveries has been made by scientists and researchers, one of which is Matthew Dodd, a researcher from University College, London. The scientists discovered a new fossil in Quebec, Canada. The fossil is evidence of bacteria that could have lived nearly about 4 billion years ago. The bacteria created tubes and filaments made of iron oxide and they lived in underwater deep sea hydro-thermal vents.

“If these rocks do indeed turn out to be 4.28 billion years old, then we are talking about the origins of life developing very soon after the oceans formed 4.4 billion years ago” said Matthew Dodd.

Scientists and researchers study these fossils and use the research to learn more about life before humans. These discoveries help scientists learn  about the history of the Earth and the organisms that lived on it from the beginning. They can help us to make sense of this history and to learn about how creatures evolved and the structures of food chains in ancient times.

Some experts, however are not convinced that the fossils represent life that long ago. “The thing that bothers me most about these structures is the fact that they all seem to be extremely oriented. They are parallel to each other and microbes don’t grow parallel to each other,” says Frances Westall, an expert on ancient fossil bacteria at the French national centre for scientific research.
