Using state-of-the-art computer simulations of fossils from the Ediacaran time period – approximately 565 million years ago – scientists discovered how these animals mixed the surrounding seawater. This may have affected the distribution of important resources such as food particles and could have increased local oxygen levels.
Through this process, the scientists think these early communities could have played a crucial role in shaping the initial emergence of large and complex organisms prior to a major evolutionary radiation of different forms of animal life, the so-called Cambrian ‘explosion’.
La simulation fait des miracles, et recrée le passé à partir de presque rien ? Et l’on se dit que nous résultons d’une chaîne de phénomènes hautement curieux et improbables ?
