Signs of oldest life on Earth discovered
According to the journal Science Advances, an international group of scientists has claimed to have found the oldest signs of life on Earth in fossil rock 4280 million years old.
Using several different lines of evidence, our study strongly suggests that many types of bacteria existed on Earth between 3750 and 4280 million years ago.
This means that life could have started 300 million years after the formation of the Earth.
In geological terms, this is the fact: about one revolution of the Sun around the Milky Way," said study lead author Saint Dominique Papineau.
However, some experts questioned whether the traces, which date back about 300 million years, which are believed to be the first signs of ancient life, were biological in origin.
After further analysis in subsequent years, the team found hundreds of distorted globular structures near one side, about a centimeter long with parallel branches, as well as tubes and filaments.
The specialists estimate that some of these structures could indeed have been generated by chance chemical reactions
But the stem was most likely of biological origin, as no such structure appears to have arisen from chemistry alone, explained a statement from University College London (UK).
