  • Deeper ocean waters were anoxic during the Neoproterozoic. Geochemical data suggest a transition from sulphidic to iron-rich mid-depth waters about one billion years ago, coincident with increased iron influx from the supercontinent Rodinia.

  • Isotopic evidence from carbon and sulphur points to the spread of anoxia and toxic sulphide as the chief culprits in at least one of a series of crises for marine ecosystems during the nascent stages of early animal evolution. See Letter p.80

  • The Cambrian explosion of biological diversity has been associated with widespread ocean oxygenation, yet early Cambrian ocean redox conditions remain controversial. Here, the authors present a suite of molybdenum isotope data and show that the ocean was oxygenated to modern-like levels by 521 Ma.

  • The oxygenation of the Earth's deep oceans is often thought to have triggered the evolution of simple animals. A review article proposes that instead, the evolution of animal life set off a series of biogeochemical feedbacks that promoted the oxygenation of the deep sea.
