CNRS and the University of Poitiers provided photographs of the fossil traces of the 21-million-year-old movement Abderrazak El Albani
The organization has already had the ability to move 2.1 billion years ago, according to a study describing the resurrection of debate on the first complex life on earth and the "oldest fossil evidence of the resurrection".
"Exercise is an indicator of specific + biologic elaboration," explains Abderrazak El Albani of the University of Poitiers, co-author of a study published in the American Academy of Sciences's Bulletin. (PNAS).
The first form of life appeared on Earth about 3.5 billion years ago.
Complex organisms, such as plants and mammals, have so-called "eukaryotic cells" in which the chromosomes are in the nucleus. Some scientific agreements track the emergence of eukaryotes to 1.8 billion years.
"With all the respect for the bacterial world, we have found signs of vertical movement, he can not do that," says the geologist. "It's a eukaryote!"
So far, the oldest traces of mobility found in Australia, the United States, Canada and Africa were 570 million years ago.
Abderrazak El Albani and his colleagues began a sensation in 2010 by announcing the discovery of a 2.1 billion-year-old "multicellular" organism fossil already in the same place in Gabon. 1.5 billion years earlier than scientifically proven at the time of publication
The "biological boom" was made possible by environmental changes. At that time, the Earth came out of the Ice Age. By melting, ice releases a great deal of oxygen and nutrients, so life can undergo a new dimension of evolution, the geologist explained.
The magnitude of this discovery gained the cover of the British science journal Nature in 2010. According to experts, "it has asked more questions than answers."
Since then, El Albani has been constantly searching for "a unique location in terms of conservation" at the Franceville Basin in Gabon, along with researchers from the international team, "traces of mobility".
The CNRS statement states, "This is about a relatively constant diameter (several millimeters), a somewhat flexible tubular structure, crossing a laminate (thin layer)".
"Their analysis of their geometry and their chemical composition shows that their origin is biological and they are concurrent with sediment deposition," the statement added.
