This article has been reviewed according to Science X's editorial process and policies . Editors have highlighted the following attributes while ensuring the content's credibility: In a study published in Science Advances, scientists have used new lithium isotope (δ7Li) data to show that continental clay export promoted organic carbon burial and thus atmospheric oxygenation during the Cambrian period. Animals depend on oxygen for respiration. Thus, the emergence and proliferation of early animals from the late Neoproterozoic to the early Paleozoic era (~600–500 million years ago or mya) has traditionally been...
