Fossils have been found that may represent the beginning of life on Earth


A set of fossils was found in Canada, and these may be one of the oldest forms of life on planet Earth, according to a new study published this month in Nature.

This is undoubtedly news that can change the perception of the world as we know it today. A group of researchers announced they had discovered a set of fossils in Canada containing traces of an ancient bacterium, and this may be the earliest evidence of the existence of life on Earth. The tiny filaments and tubes formed by bacteria were found in a remote geological zone in eastern Canada, called the Nuvvuagittuq, which had already been explored for the first time in the 1990s.

Retained and preserved in quartz, in what is thought to be an ancient underwater hydrothermal system where the first life forms emerged, scientists believe fossils are between 3.7 and 4.4 billion years old. So, it is suggested that these emerged 340 million years after Earth was formed, explained The New York Times.

Some experts were skeptical of the findings of Mattew S.Dodd, Dominic Papineau and the rest of the team. Martin J. Van Kranendonk, a geologist at the University of New South Wales in Australia, responsible for the 3.7 billion-year fossil discovery in Greenland last August, described the pattern discovered on Canadian rocks as dubiofossils, According to an explanation to The New York Times. That is, fossil-like structures where it is not possible to prove that, somewhere in that time, there existed life.

Those responsible for the new study also ensured that they had ignored all other types of classification, thus confirming that they were indeed fossils of organisms. “Structures are composed of minerals that form from putrefaction and are well documented in geological records”, said Dominic Papineau of the University of California.

“The fact that we discovered them in one of the oldest known rock formations suggests that we have found direct evidence of one of the oldest forms of life on Earth”. In addition, fossils were formed at a time when “Mars and the Earth Liquid water to the surface, posing exciting questions about extraterrestrial life”. “So, it is to be hoped that we will find evidence of life on Mars 4 billion years ago, or, if it does not, Earth may have been an exception”, he added.
