Did you know that ... the oldest fossils in the world date back 3.7 billion years? They were found in Greenland in 2016 as published in the journal Nature. Cyanobacteria during photosynthesis release a residue that forms these structures found in Greenland, which are called stromatolites. Stromatolites have been found elsewhere, such as Australia, dating back 3.5 billion years. The Greenland discovery has been the result of the melting of the area by climate change. Thanks to this discovery, the age at which life on earth is known has receded for 220 million years.
