The previous groups were able to move 2.1 billion years ago, according to a survey published on Monday explaining "the oldest fossil routes" of cultivating and reviving the debate has been going to & # 39; The first complex form of life on Earth.

"The move is a sign of specific assignment + biological +", which is described to AFP Abderrazak El Albani at the University of Poitiers, co-author of the study published in the Academy of American Sciences (PNAS) Affairs.

First life appeared on Earth around 3.5 billion years ago.

"Eukaryotic" cells are known as "eukaryotic" cells, with chromosomes kept in compactness in computer life formats, such as plants and mammals. A special scientific consensus continues to have their eukaryotes a & # 39; reach 1.8 billion years.

"We found signs of direct, oblique, horizontal, with all my respect for the bacterial world, that can not move," said the geologist. "It's usually eunkaryotes!"

To date, the oldest behavioral signs found in Australia, the United States, Canada, Africa … were 570 million years old.

Abderrazak El Albani and his colleagues had already been aware of in 2010 by announcing the solution, at the same site in Gabon, on fossils of "multi-class" organisms that are 2.1 billion years to age, that is, to 1.5 billion years earlier than scientifically at the time of publication.

"Biological promotion" has been made possible through environmental change. At that time, the land was getting out of ice age. By melting, leaving behind a large amount of oxygen and nutrition that allows life to exceed a new level of development, explains the expert.

The size of this research in 2010 gained the cover in the Scottish Natural Science magazine, although it is, "by experts," asking more questions than responded ".

Since then, with the co-ordination of the international team of researchers, Mr El Albani has always been able to find Franceville Basin, in Gaba, "a unique conservation site", a & # 39; find the "movement marks".

"It is about tubular structures, with a relatively stable measurement (several miles in size), smaller or smaller, and that crosses the laminate (sedimentary tanks), and # 39 ; CNRS statement designation.

"The study of the geometry and the chemical co-script indicates that the biological foundations are and are contemporary with sediment investment," said the statement.
