Résumé

The Youtube channel Zeste de science explores all aspects of scientific research, proving that even the most complicated scientific facts can be explained in less than 5 minutes, and that even the most seemingly trivial events of everyday life, if thoroughly studied, can contribute to the biggest technological advances.
Episode 27: What was our planet like more than 2 billion years ago? The way we envision our planet in the past tends to change with scientific discoveries and advances. Researchers from the University of Poitiers recently unearthed astonishing fossil traces in a quarry in Gabon which thus question the evolutionary chronology of life forms. After various hypotheses and analyses, these grooves seem to directly point to the existence of possibly mobile, multi-cellular life forms 2.1 billion years ago.
