L'apparition de la vie sur Terre - L'Esprit Sorcier, le mag avec Fred Courant

Over the past 4.5 billion years, millions of species have appeared, evolved, and ultimately disappeared. And we can only talk about the animal and plant species for which we have discovered fossils or traces! Even today, scientists identify and describe more than 15,000 species per year... and among this abundance, humans (Homo sapiens) only appeared recently, 200,000 years ago. What was the first "known" living being on Earth? When did it appear? What did it look like? What are the major stages and events of life on Earth? Fred takes us on a journey through time, in search of our origins. Find all episodes of the show on the Mon Science & Vie Junior app!
