L’explosion cambrienne, un mythe ?L’origine de la vie pourrait provenir non pas d’une, mais de plusieurs explosions survenues entre il y a 520 et 540 millions d’années avant notre ère

Longtemps considérée comme un "big bang" biologique, l'explosion du Cambrien suscite des débats quant à son déroulement précis. En jeu : la date et les circonstances exactes de l’apparition de la vie sur Terre.
