Researchers from University College London have found that life appeared a very short time after the Earth formed. The authors of the study believe that this is potential evidence for the existence of extraterrestrial life. Discussions continue about the samples themselves.
The authors of a new study, published in the journal Science Advances, studied a rock found near Inukjuak in northern Quebec, Canada. It was estimated to be about 3.75 to 4.28 billion years old.
In an earlier article published in the journal Nature, researchers from University College London (UCL) suggested that the tiny threads, protrusions and tubes found in the rock were created by bacteria about 300 million years before the generally accepted date of the first signs of life on Earth... →
