Paleontologists Have Found Traces of Multicellular Organisms Age 2.1 Billion Years
Organisms lived on the bottom of the sea 2.1 billion years ago.
Paleontologists from France and Canada discovered in Gabon traces of macroscopic organisms that lived at the bottom of shallow seas approximately 2.1 billion years ago. It is 600 million years before the time of life previous record.
It should be noted that skeptics argue that found by researchers of the samples were traces of colonies of bacteria or inorganic entities, for example, the nodules of sulphur.
The researchers conducted a series of analyses of the chemical composition of fossils, which confirmed that the organic traces of them still there, and traces of sulfur no. Moreover, scientists have discovered a series of fossils that can be interpreted as traces of crawling.
The discovery by researchers means that multicellular organisms appeared on Earth almost at the moment when its atmosphere began to contain appreciable amount of oxygen biogenic origin. However, it is likely that the detected multicellular soon became extinct and left no descendants.
