When scientists search for species that lived hundreds of millions of years ago, they are not always looking for old animals. Life on Earth has changed a lot over time, but sometimes a new discovery reveals a few things that have largely remained the same.
In a new article published in Nature researchers reveal the discovery of tiny microfossils At least 900 million years old – and perhaps even up to a billion years old – prove that some species of fungi exist in Europe The history of the earth are far earlier than previously thought.
The idea that life on earth began in The oceans are something that has been widely accepted by scientists, but when life drifted off the sea ̵
The fossils found in Canada point to a much earlier time date for life on land, as the researchers thought. If mushrooms had been on land a billion years ago, there would probably have been animal life.
The fossils were embedded in rock in the form of chitin, a component of fungal cells. By dating the surrounding rock, the scientists have come across the estimated age of the mushroom fossils.
"This means that if fungi existed about 900-1000 million years ago, it should have been animals," says Corentin Loron of The University of Liège, lead author of the work, AFP . "This changes our vision of the world because these groups are still present today. Therefore, this distant past, though very different from today's, may have been much, more modern, than we thought. "
It is an interesting discovery, that of the imagination in relation to the overall picture of the landscapes leaves a lot. Life on Earth a billion years ago is still a tantalizing glimpse into the past.
